There is no universally best VSync setting. On a fixed-refresh monitor, turn VSync on if you want to eliminate distracting screen tearing, and turn it off if the lowest possible presentation latency matters more than a perfectly clean image. On a monitor with G-SYNC, FreeSync, or Adaptive-Sync, enable VRR first, then keep the game within the monitor’s supported refresh-rate range with a frame cap or the appropriate VSync setting. If frame generation is enabled, test that combination separately because generated frames change the timing and latency trade-offs.
- Fixed-refresh display + visible tearing: VSync on.
- Competitive shooter or rhythm game: Start with VSync off if you can tolerate tearing; use a good frame limiter or VRR configuration where available.
- G-SYNC, FreeSync, or Adaptive-Sync display: Enable VRR and prevent the frame rate from regularly exceeding the display’s maximum refresh rate.
- DLSS or FSR frame generation: Follow the game or GPU vendor’s guidance and test VSync, VRR, and the frame cap together.
VSync does not make a slow GPU faster, improve texture or rendering quality, or guarantee a higher frame rate. It primarily changes when completed frames are presented to the display.

What VSync actually changes
VSync, short for vertical synchronization, synchronizes a game’s frame presentation with the display’s refresh timing. Its main purpose is to prevent the display from showing parts of two different frames during one refresh.

- The game renders a frame into a back buffer.
- The game submits that frame with a present operation.
- With traditional VSync enabled, presentation waits for an appropriate vertical-blank interval rather than updating immediately.
- The display begins showing the completed frame at the next refresh boundary.
- If the frame is late, the previous frame may remain on screen for another refresh interval.
In Microsoft’s DXGI terminology, a Present call with a sync interval of 0 presents immediately, while sync intervals from 1 through 4 synchronize presentation to one or more vertical blanks. The underlying details vary between DirectX, Vulkan, OpenGL, the game engine, the driver, and the display mode, but the important point is that VSync is fundamentally a presentation-timing choice, not merely an FPS counter limit. See Microsoft’s documentation for IDXGISwapChain::Present and DXGI presentation constants.
FPS, refresh rate, and why tearing happens
FPS is how quickly the game produces frames. Refresh rate, measured in hertz (Hz), is how often the display can begin a new refresh. These are related, but they are not the same thing.
| Display refresh rate | Approximate time per refresh |
|---|---|
| 60 Hz | 16.67 ms |
| 75 Hz | 13.33 ms |
| 120 Hz | 8.33 ms |
| 144 Hz | 6.94 ms |
| 165 Hz | 6.06 ms |
| 240 Hz | 4.17 ms |
A 60 Hz monitor can begin a new refresh every 16.67 milliseconds, but the GPU might produce frames at 40, 63, or 100 FPS. Without synchronization, the display can start scanning one frame and receive a newer frame before the scan is complete. The upper portion of the screen then belongs to one frame while the lower portion belongs to another. That horizontal discontinuity is screen tearing.
Tearing is especially obvious during a fast horizontal camera movement. It is common when FPS exceeds a fixed refresh rate, but that is not the only possible condition. Asynchronous presentation and irregular frame timing can produce tearing at other frame rates too. AMD’s frame-generation documentation describes VSync-off operation with VRR disabled as capable of tearing across the frame-rate range.
The display also may not show every frame the GPU renders. A 200-FPS counter on a 60 Hz monitor does not mean that all 200 frames are visible. Some frames may be replaced before the display completes a refresh, or may never be presented at all.
To check what Windows is actually using, open Start > Settings > System > Display > Advanced display. Select the correct monitor if more than one is connected, then inspect or change its refresh rate. The available options depend on the display, cable, GPU, resolution, and driver. Microsoft’s Windows refresh-rate instructions also cover Dynamic Refresh Rate.
VSync on versus VSync off
| Setting | Tearing | Latency | Frame-rate behavior | Good starting point for |
|---|---|---|---|---|
| VSync on | Normally prevented on a fixed-refresh display | Can increase because presentation may wait for a refresh boundary | Presentation follows the display’s cadence; missed deadlines can repeat a frame | Single-player, cinematic, or casual games where clean motion matters |
| VSync off | Possible, including during irregular presentation | Usually minimizes synchronization waiting, though queueing and other delays still matter | May run above the display’s refresh rate, unless another limiter or timing mechanism intervenes | Competitive play, benchmarking, and players who tolerate tearing |
| Adaptive VSync | Reduced above the refresh rate; may return below it | Variable | Driver behavior changes according to FPS | A fixed-refresh compromise on supported NVIDIA systems |
| VRR | Usually minimized while FPS remains within the supported range | Usually lower than traditional fixed-refresh VSync, but not zero | The display changes its refresh timing to follow frame delivery | Most modern gaming setups with a compatible monitor |
Turning VSync off does not guarantee unlimited FPS. A game’s own frame cap, a driver limiter, CPU or GPU bottlenecks, the Windows compositor, or API-specific presentation behavior can still limit the result. Microsoft explicitly notes that disabling VSync does not necessarily uncap frame rate.
What VSync does well
It prevents the most obvious form of tearing
On a fixed-refresh display, traditional VSync makes the game wait for the display’s refresh boundary before presenting a new frame. NVIDIA describes this as synchronizing application frame rate with display refresh to eliminate tearing, and Intel likewise identifies aligned frame presentation as the main benefit. VSync improves the integrity of presentation; it does not improve resolution, anti-aliasing, textures, lighting, or other rendering quality.
It can make motion look more orderly
If the game can reliably deliver frames at the display’s cadence, a sequence of complete, evenly presented frames can look smoother than a higher average FPS accompanied by irregular frame replacement. Average FPS alone does not describe frame pacing.
It can avoid needless rendering above the display ceiling
On a fixed-refresh monitor, VSync can stop the game from presenting more frames than the display can refresh. Depending on the title and implementation, that may reduce GPU power use, heat, and fan noise. It is a possible side benefit, not a guarantee: a game may continue rendering ahead, queue frames, or use a separate limiter.
The drawbacks: latency, stutter, and frame queues
Presentation can wait
With traditional VSync, a frame that finishes just after a refresh boundary may wait for the next one. Intel notes that missing a synchronization point can introduce latency. The delay is not a universal fixed number: it depends on when the frame finishes, the refresh rate, buffering, the number of frames in flight, CPU and GPU load, the graphics API, the driver, the presentation mode, and the game’s frame pacing.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesThe refresh intervals above provide useful scale. A possible missed boundary is measured in roughly 16.67 ms at 60 Hz but roughly 4.17 ms at 240 Hz. That does not mean VSync automatically adds one full refresh of input lag, only that the timing opportunity is much coarser at a lower refresh rate.
Missed deadlines can create cadence drops
If a game cannot finish a frame before the next refresh boundary, the previous frame may be displayed again. On some traditional double-buffered implementations, a workload that normally runs at 60 FPS can fall into a 30-FPS-like cadence after missing deadlines. This is a common implementation behavior, not an unavoidable property of every modern VSync system. Buffering, frame pacing, adaptive modes, and the game engine all affect the result.

NVIDIA’s Adaptive VSync was designed in part to avoid the conspicuous stutter that can occur when FPS falls below a fixed display refresh rate: it enables synchronization above the refresh rate and disables it below. It may allow tearing when FPS is below the ceiling, so it is a compromise rather than a universal replacement.
Queued frames can matter as much as VSync
VSync is only one part of end-to-end latency. If the CPU runs ahead and the game or driver allows several frames to sit in a queue, input can take longer to reach the displayed image. Microsoft warns in its Direct3D 12 swap-chain guidance that failing to limit frames in flight can create an unbounded queue and inflate input latency. A VSync-off configuration can also feel delayed if it allows excessive queueing.

Blaming every delay on VSync leads to poor tuning decisions.
VSync versus a frame limiter
These controls solve different problems:
- VSync controls when completed frames may be presented relative to the display’s refresh timing.
- A frame limiter restricts how quickly the game renders or submits frames.
- VRR allows the display’s refresh timing to vary within a supported range.
A frame limiter by itself can reduce queue buildup, power use, and heat, but it does not necessarily prevent tearing on a fixed-refresh display. VSync can prevent tearing but still suffer from missed-refresh stutter or excessive queued frames. Combining the right presentation mode with a sensible cap often gives better results than relying on either control alone.
For a VRR monitor, a cap slightly below the display’s maximum refresh rate is a practical starting point when the game regularly hits the ceiling. The exact margin depends on limiter accuracy, frame-time spikes, the game, driver, and monitor. There is no universal rule that the cap must be exactly two or three FPS below maximum. Test the result rather than treating that number as a law.
Double buffering and triple buffering
Double buffering
In a simple double-buffered arrangement, one buffer is being displayed while another is being rendered or waiting to be displayed. Traditional VSync can provide tear-free presentation, but if the next frame misses its deadline, the currently displayed frame may be repeated. That is one reason a near-constant frame rate can suddenly look like a lower cadence.
Recommended Free Tools
Triple buffering
Triple buffering adds another buffer. It can let the GPU continue rendering while one frame is displayed and another waits, reducing some forms of stutter. However, allowing more frames to queue can also increase input latency and memory use. It is not a universal fix for VSync stutter.
Be careful about what a driver checkbox actually controls:
- NVIDIA’s Control Panel Triple buffering option applies to OpenGL applications and improves performance when VSync is enabled.
- AMD documents OpenGL triple buffering as requiring VSync and applying only to OpenGL 3D applications.
- DirectX 11, DirectX 12, and Vulkan games may implement their own buffering and frame pacing. A driver’s OpenGL triple-buffering option may have no effect on them.
Game-specific buffering, flip-model swap chains, low-latency modes, and frames-in-flight limits can matter more than a similarly named driver option.
VSync versus G-SYNC, FreeSync, and Adaptive-Sync
Traditional VSync keeps the display fixed
With traditional VSync, the monitor continues refreshing at a fixed rate such as 60, 144, or 240 Hz. The application waits for fixed refresh boundaries. This can prevent tearing, but a late frame may cause a wait, a repeated frame, or additional queueing.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
VRR lets the display follow the frame rate
Variable refresh rate, or VRR, allows a compatible display to change when it starts its next refresh so that it follows the game’s frame delivery within a supported range. NVIDIA G-SYNC, AMD FreeSync, and VESA Adaptive-Sync are VRR technologies or implementations. NVIDIA describes G-SYNC as matching monitor refresh rate to GPU frame rate. AMD describes FreeSync as using DisplayPort Adaptive-Sync and HDMI variable-refresh protocols to synchronize display refresh with GPU frame delivery.
VRR can reduce tearing and unevenness without forcing every frame to wait for a fixed cadence. It is usually the best balance of smoothness and latency when the monitor, connection, GPU, driver, and game support it. It is not magic, however.
VRR has a lower range and a ceiling
A monitor may advertise a range such as 48–144 Hz. Below its minimum, some displays use Low Framerate Compensation (LFC), duplicating frames so the display remains within its operating range. AMD documents LFC as part of FreeSync behavior on supported displays.

- use a vendor mode such as NVIDIA Fast VSync or AMD Enhanced Sync where appropriate; or

G-SYNC or FreeSync therefore does not automatically solve every tearing problem at every FPS. A frame cap below the ceiling is often the cleanest approach, while the ideal VSync choice depends on the game and the latency priority.
Which setting should you choose?
| Your situation | Recommended starting point | Reason |
|---|---|---|
| Fixed-refresh monitor, obvious tearing, casual or cinematic game | VSync on | Prioritizes complete, tear-free frames. |
| Fixed-refresh monitor, competitive game, tearing tolerated | VSync off | Reduces synchronization waiting and preserves render throughput. |
| Fixed-refresh monitor, FPS often below refresh rate | Test VSync off, Adaptive VSync, or a game-specific limiter | Traditional VSync can make missed-refresh behavior more noticeable. |
| G-SYNC, FreeSync, or Adaptive-Sync display | Enable VRR and keep FPS inside its range | Usually the best compromise between smoothness and latency. |
| VRR display, FPS regularly above maximum refresh | Use a cap below the ceiling or the vendor-recommended VSync behavior | VRR cannot cover output above its maximum range. |
| DLSS or FSR frame generation enabled | Use the game or vendor-recommended combination, then test it | Generated frames change pacing, queueing, and refresh-ceiling behavior. |
| Benchmarking maximum GPU throughput | VSync off | NVIDIA’s FrameView guidance uses VSync off for measuring full performance, with tearing as the trade-off. |
| Laptop on battery | VSync or a frame cap may be preferable | Limiting unnecessary rendering can reduce power, heat, and fan noise. |
For a fixed-refresh display
Choose VSync on when tearing is clearly visible and the game can maintain the monitor’s cadence. This is a sensible default for slower-paced games, RPGs, strategy games, and cinematic single-player titles.
Choose VSync off when input responsiveness and maximum render throughput are more important than tearing, particularly in competitive shooters. If the game produces wildly fluctuating FPS, try a frame limiter or an adaptive driver mode rather than assuming that uncapped output will feel best.
For a VRR display
Enable VRR in the monitor’s on-screen display and in the relevant GPU software. Then make sure the game does not spend much time above the monitor’s maximum refresh rate. NVIDIA recommends a tear-free G-SYNC configuration using VSync with NVIDIA Reflex or Ultra Low Latency Mode; those latency features can cap FPS below the display ceiling and avoid VSync backpressure. NVIDIA notes that this has slightly higher latency than uncapped FPS with Reflex, so competitive players should compare both approaches in their game.
AMD explicitly recommends turning on VSync or capping the frame rate when FPS regularly exceeds the display’s refresh rate. On either platform, use the game’s own limiter if it is accurate and stable, or a suitable driver-level limiter. Keep in mind that a cap is a tuning tool, not a universal numeric formula.
For competitive games
Start with the highest stable Windows refresh rate, VRR if available, a sensible frame cap, and the game’s low-latency feature. Compare VSync on and off under identical conditions. If you can see tearing and it does not bother you, VSync off may minimize presentation waiting. If tearing distracts you, a VRR setup or VSync-on setup may produce a better practical result even if a latency test shows a small disadvantage.
Frame generation needs separate testing
DLSS, FSR, and other frame-generation systems create additional displayed frames between traditionally rendered frames. They can make motion look smoother, but they do not make input sampling or game simulation run at the generated frame rate. The underlying rendered frames still determine much of the game’s input-to-simulation latency.
Frame generation also changes the relationship between output FPS and monitor refresh. If generated output exceeds the display’s capacity, frames may queue or be dropped. VSync can cause additional waiting or repeated display intervals when generated output does not match the monitor’s refresh behavior.

NVIDIA’s Streamline DLSS-G programming guide documents VSync limitations involving Dynamic Multi Frame Generation, Vulkan, GeForce NOW, and Independent Flip. AMD’s FSR frame-interpolation swap-chain documentation and FSR frame-generation guidance likewise describe pacing, VSync, VRR, and latency caveats.
Practical frame-generation rule: first test with frame generation disabled so that you understand the game’s native frame pacing. Then enable it and retest the recommended VSync, VRR, Reflex or Anti-Lag, and frame-cap combination for that specific game. Do not assume a setting that works in one title will work in another.
Adaptive, Fast, Enhanced, and Smart VSync are not the same thing
Driver software uses similar names for different technologies. Do not confuse Adaptive VSync with Adaptive-Sync: the former is a synchronization behavior, while the latter is a display VRR standard or capability.
NVIDIA Adaptive VSync
NVIDIA Adaptive VSync turns VSync on when FPS is above the display’s refresh rate and off when FPS falls below it. This avoids forcing below-refresh output to remain synchronized, but tearing can return during those lower-FPS periods. It is not the same as owning a variable-refresh monitor.

NVIDIA Fast VSync
NVIDIA documents Fast VSync as a mode intended to reduce latency without introducing tearing in suitable situations. Its availability and behavior depend on the GPU, driver, application, and configuration; NVIDIA’s reference associates it with Pascal and later GPUs in single-GPU configurations. Treat it as a per-game experiment, not a universal replacement for VRR.
AMD Enhanced Sync
AMD Enhanced Sync is a driver synchronization mode intended to reduce some latency and stutter associated with traditional VSync, particularly when frame rate exceeds display refresh. AMD says it supports DirectX 9 through 12 and Vulkan, but not OpenGL. AMD also warns that it may cause flicker or undesirable behavior in multimedia applications, so use it per game rather than globally for every program.
Intel Smart VSync and Smooth Sync
Intel Arc Control includes several frame-delivery choices:
- Application Choice: use the game’s VSync setting.
- Smart VSync: enable VSync above the display refresh rate and disable it below.
- Smooth Sync: apply a dithering filter intended to make tearing less distracting on displays without VESA Adaptive-Sync. It does not turn the monitor into a VRR display.
Intel documents these options in its Arc Control frame-delivery settings guidance.
How to change VSync and refresh-rate settings
Labels and available options vary by game, Windows version, GPU, driver, API, laptop display routing, and presentation mode. Prefer a game’s own setting when it works correctly, and change one variable at a time.
Check Windows 11’s refresh rate
- Open Start > Settings.
- Go to System > Display > Advanced display.
- Select the target display.
- Check the active refresh rate and select the highest stable rate appropriate for the monitor.
- If Dynamic Refresh Rate is available, test it separately. Windows 11 DRR requires a VRR-capable display with at least 120 Hz and can limit the maximum refresh rate in some games. Disable DRR if a title behaves as though it is running at a lower refresh rate.
Change it in the game
The usual path is Settings > Graphics, Display, or Video, followed by VSync, Vertical Sync, or Wait for Vertical Refresh.
- Choose On for tear-free fixed-refresh presentation.
- Choose Off for minimum synchronization delay or maximum throughput.
- Choose Adaptive, Fast, or Smart only when you know which implementation the game or driver is using.
Restart the game after changing the setting if the title does not apply display changes immediately.
NVIDIA Control Panel
- Open NVIDIA Control Panel.
- Select Manage 3D settings.
- Open Program Settings.
- Select the game, or add its executable if it is not listed.
- Find Vertical sync.
- Choose Use the 3D application setting, On, Off, Adaptive, or Fast, depending on the desired behavior and supported hardware.
- Click Apply.

Troubleshooting VSync problems
VSync is on, but I still see tearing
- Confirm that the game is using the intended GPU and display.
- Verify that Windows is set to the monitor’s actual high-refresh mode.
- Check that the monitor’s VRR, FreeSync, or G-SYNC option is enabled in its OSD when applicable.
- Check whether the game’s VSync setting is overriding the driver, or the driver is overriding the game.
- Test the intended fullscreen or borderless mode; some driver controls apply only to particular presentation paths.
- Disable overlays, capture tools, and frame-generation features temporarily.
- On a VRR display, make sure FPS is not regularly exceeding the VRR ceiling.
VRR presentation has its own requirements. Microsoft documents that supported VRR swap chains use tearing-enabled presentation flags internally even though the intended visible result is tear-free variable refresh. If the game or display path does not support the necessary behavior, enabling a checkbox may not be enough.
VSync causes stutter
Possible causes include an unstable frame time, a missed refresh deadline, excessive buffering, a half-refresh mode, disabled VRR, FPS outside the VRR range, or frame generation producing an unsuitable output cadence.
Try this recovery order:
- Verify the monitor’s refresh rate in Windows.
- Enable VRR if the monitor supports it.
- Lower demanding graphics settings until frame times are more stable.
- Try a frame cap below the display’s maximum or below the VRR ceiling.
- Try Adaptive VSync, Fast VSync, or Enhanced Sync only if the GPU and game support the mode.
- Disable frame generation temporarily to identify whether it is the cause.
- Check overlays, recording software, and other capture tools.
VSync causes input lag
First compare VSync on and off in the same game under the same resolution, refresh rate, frame cap, and graphics settings. Use the highest stable refresh rate, avoid unnecessary frames in flight, and use the game’s limiter or vendor low-latency feature where it behaves well.

Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteTraditional VSync can add presentation waiting, but there is no universal number of milliseconds to assign to it. The result depends on timing, buffering, queue depth, frame pacing, API, presentation mode, and whether the game is CPU- or GPU-bound. A badly managed frame queue can create substantial latency independently of the basic VSync choice.
VSync locks the game to 30 FPS
Check for these causes:
- The game is missing the display’s refresh deadline.
- A half-refresh or adaptive-half-refresh option is selected.
- The monitor is running at 60 Hz instead of its intended high-refresh mode.
- The game has a separate 30-FPS cap or cinematic mode.
- Frame generation or another pacing feature is imposing a limit.
On a 60 Hz display, each refresh lasts about 16.67 ms. If a frame is not ready for one boundary, some implementations show the previous frame for another interval, producing a 30-FPS-like cadence. That is an implementation and timing behavior, not a universal rule that VSync always locks games to 30 FPS.
The driver VSync setting does nothing
The game may use an API or presentation path that the driver profile does not control. Other possibilities include windowed or borderless presentation, a hybrid laptop display path, the game’s own setting taking precedence, a profile assigned to the wrong executable, a game that needs to be restarted, or frame generation and an engine-specific swap chain changing the behavior.
Intel documents that its VSync controls may apply only to full-screen games or applications. NVIDIA also documents that some settings apply only when the display is connected to the NVIDIA GPU. Check the correct executable, GPU, display connection, and presentation mode before concluding that the setting is broken.
FreeSync or G-SYNC is missing
- Enable the feature in the monitor’s OSD.
- Use a compatible DisplayPort or HDMI connection and the appropriate cable.
- Set the monitor to its supported refresh rate.
- Update the GPU driver and monitor firmware if the manufacturer recommends it.
- Check whether a monitor preset disabled FreeSync or another VRR option.
- On a laptop, check which GPU physically drives the internal or external display.
- For NVIDIA, verify the monitor appears under Display > Set up G-SYNC.
- For AMD, verify FreeSync appears in Adrenalin’s Display settings.
FreeSync is not restricted in every case to AMD GPUs: AMD documents support for some non-AMD GPUs that support DisplayPort Adaptive-Sync, subject to the particular hardware and compatibility.
Frame generation feels sluggish or uneven
Disable frame generation and compare the game’s native frame pacing first. Then check the game developer’s recommended combination of frame generation, VSync, VRR, Reflex or Anti-Lag, and frame cap. A high displayed FPS number can improve perceived smoothness without making input and simulation respond at the same rate, and output above the monitor’s ceiling can create queueing or repeated-refresh behavior.
A practical way to test your own setup
- Identify the display: fixed refresh or VRR, and note its actual supported range.
- Set the intended Windows refresh rate: do not test VSync while Windows is accidentally using 60 Hz on a 144 Hz monitor.
- Disable frame generation temporarily: establish a baseline with native frames.
- Watch frame time, not only average FPS: inconsistent frame times can look bad even when the FPS average is high.
- Test VSync off: note tearing, responsiveness, and frame pacing.
- Test VSync on: note whether tearing disappears and whether missed-refresh stutter or delay becomes apparent.
- If you have VRR, test VRR with a stable cap: begin slightly below the monitor’s maximum refresh rate, then adjust based on actual behavior.
- Re-enable frame generation: repeat the comparison because its pacing requirements may differ.
Use the same scene, camera movement, resolution, graphics settings, and cap for each test. A configuration that looks best in a slow single-player game may not be the right choice for a competitive shooter.
Bottom line
VSync is best understood as a way to control frame presentation timing. On a fixed-refresh display, enable it for a clean, tear-free image and disable it when minimum synchronization delay matters more. On a G-SYNC, FreeSync, or Adaptive-Sync display, enable VRR and keep FPS within the supported range; use a cap or VSync as the strategy for output above the refresh ceiling. Treat frame generation as a separate tuning problem, and judge the result by tearing, frame-time consistency, and input response—not by the FPS counter alone.

Frequently Asked Questions
Does VSync lower FPS?
It can limit or synchronize presentation to the display’s refresh cadence, so the displayed or reported FPS may fall to the refresh rate or a lower cadence when frames miss deadlines. It does not make the GPU render faster, and a separate game or driver limiter can affect FPS even with VSync off.
Does VSync improve graphics quality?
No. VSync does not improve resolution, textures, lighting, anti-aliasing, or image detail. It improves presentation integrity by reducing or eliminating tearing on a fixed-refresh display.
Should VSync be on with G-SYNC or FreeSync?
Enable VRR first and keep FPS below the monitor’s maximum refresh rate with a suitable cap. Whether VSync should also be enabled depends on the GPU vendor, game, and latency target. NVIDIA recommends a tear-free G-SYNC configuration using VSync with Reflex or Ultra Low Latency Mode, while AMD recommends VSync or a frame cap when FPS regularly exceeds the display’s refresh rate.
Is Adaptive VSync the same as Adaptive-Sync?
No. Adaptive VSync is a driver synchronization behavior that can switch VSync on or off according to FPS. Adaptive-Sync is a display variable-refresh technology used by compatible monitors and GPUs.
The Bottom Line
The simple rule: fixed-refresh monitor plus distracting tearing means VSync on; latency-first competitive play means VSync off if tearing is acceptable. With G-SYNC, FreeSync, or Adaptive-Sync, use VRR and keep FPS within its range, then test the cap and VSync behavior—especially when frame generation is enabled.
