It reduces screen tearing, but may add input latency or cause stutter if a game cannot keep pace. Whether it is worth enabling depends on the game, display, graphics hardware, and how much you value tear-free visuals versus responsiveness.
How V-Sync affects FPS
V-Sync, or vertical synchronization, coordinates a game’s frame presentation with the display’s refresh rate to reduce tearing. With synchronization enabled, frames are presented in step with the display rather than as soon as the GPU finishes them. That can constrain the FPS reaching the screen to the display’s refresh cadence or a related cadence supported by the implementation. The exact behavior depends on the game, driver, display, and buffering.
If the system cannot sustain the required cadence, fixed V-Sync can produce uneven frame pacing or stutter, and some implementations may drop presentation to a lower cadence. This is not a universal percentage loss: there is no single FPS reduction that applies to every system. Intel describes V-Sync as synchronizing application frame rate with monitor refresh, while NVIDIA documents the stutter trade-off when performance falls below the V-Sync cap (Intel Support; NVIDIA Adaptive VSync).
What changes when you turn it off?
With V-Sync off, a game can render and present frames without waiting for the display’s refresh cadence, so FPS may rise beyond the display’s refresh rate. Intel calls this “virtually unlimited” FPS, but also warns that tearing, jerkiness, or stuttering may be more likely depending on the configuration (Intel Support). A higher FPS counter does not necessarily mean every frame appears cleanly: the display may show parts of multiple frames at once, creating a tear line.

V-Sync can also affect input latency because waiting to synchronize presentation may delay when a completed frame appears. The amount is not fixed across games or configurations, and the available evidence does not support a universal millisecond figure. NVIDIA’s guidance for G-SYNC setups describes a low-latency configuration using V-Sync alongside Reflex or Ultra Low Latency Mode, while noting it has slightly more latency than uncapped Reflex (NVIDIA system latency guide).
Compare the trade-offs
| Setting or approach | Tearing | Frame pacing and stutter | FPS and responsiveness | Compatibility |
|---|---|---|---|---|
| Fixed V-Sync on | Reduces tearing by synchronizing frame presentation with display refresh. | Can look uneven or stutter if the game cannot sustain the display cadence; behavior depends on implementation. | Can constrain presented FPS; synchronization may add latency. | Depends on the game, driver, display, and buffering. |
| V-Sync off | Tearing is more likely. | Jerkiness or stutter may occur depending on the setup. | Can allow FPS beyond refresh cadence and avoid synchronization waiting. | Depends on the game and display; no specific mode required. |
| Adaptive V-Sync | NVIDIA describes it as locking when performance is above the V-Sync cap, reducing tearing. | NVIDIA describes it as unlocking synchronization below the cap to reduce stuttering. | Behavior changes with performance relative to the cap. | NVIDIA driver feature; availability depends on the graphics setup. |
| Variable refresh rate (VRR), such as FreeSync | Can reduce or eliminate tearing when compatible equipment is used. | AMD says FreeSync synchronizes a compatible display’s refresh rate with graphics-card frame rate to reduce or eliminate tearing and stuttering. | Display refresh follows changing frame rates within supported operation; exact range is model-specific. | Requires compatible GPU and display; check the model’s support and VRR range. |
When to use V-Sync
Turn it on when tearing bothers you
Enable V-Sync if a visible tear line is distracting and you prefer a synchronized image to uncapped FPS. It can be a sensible starting point in slower-paced games or when performance is comfortably consistent with the display cadence. Then check the actual game for unwanted stutter or delayed-feeling controls.

Turn it off when responsiveness or uncapped FPS matters most
For competitive or fast-response play, you may prefer V-Sync off if minimizing input delay is more important than avoiding tearing. It can also suit players who want the game to render above the display’s refresh rate and are comfortable with the visual trade-off. Test in the game you play rather than assuming the same setting will feel identical everywhere.
Consider Adaptive V-Sync if fixed synchronization stutters
NVIDIA describes Adaptive V-Sync as disabling synchronization when FPS falls below the cap and enabling it again when performance recovers. This aims to reduce stuttering during dips while limiting tearing when frame rate is higher. It is a specific NVIDIA feature; do not assume another driver or display’s similarly named setting behaves the same way (NVIDIA Adaptive VSync).

Consider VRR if your GPU and monitor support it
Variable refresh rate lets a compatible display adjust its refresh rate to follow changing frame rates, rather than requiring every frame to arrive at one fixed cadence. AMD describes FreeSync as synchronizing a compatible display with the graphics card to reduce or eliminate tearing and stuttering. Confirm that your specific monitor and GPU support the same VRR mode and check the monitor’s supported range; FreeSync and fixed V-Sync are not interchangeable labels (AMD FreeSync support).
A practical way to choose
- Start with the symptom. If you see tearing and it distracts you, try V-Sync on. If controls feel less responsive or you prioritize maximum uncapped FPS, try it off.
- Play a representative section of the game. Watch for tear lines, uneven motion, and whether controls feel delayed. A change in the FPS counter alone does not settle which setting feels better.
- If V-Sync on stutters, check alternatives. Look for Adaptive V-Sync in the applicable NVIDIA driver settings, a frame-rate limiter in the game or driver, or a VRR mode supported by both the display and GPU.
- For NVIDIA G-SYNC, use configuration-specific guidance. NVIDIA’s system-latency guide discusses V-Sync with Reflex or Ultra Low Latency Mode for G-SYNC, with slightly more latency than uncapped Reflex. Treat that as guidance for the described NVIDIA ecosystem, not a universal preset (NVIDIA system latency guide).
What to check before changing hardware
You do not need to buy a variable-refresh monitor just to use V-Sync. If you are considering VRR because fixed synchronization is not giving you smooth results, verify the exact monitor model’s VRR range and compatibility with your GPU before choosing hardware. Support and behavior vary by model and configuration; AMD’s FreeSync documentation explains the compatible-equipment requirement (AMD FreeSync support).
