For most players who want competitive responsiveness without visible tearing, enable G-SYNC, enable Vertical sync in the NVIDIA Control Panel, disable in-game V-SYNC, use NVIDIA Reflex when available, and cap FPS slightly below the monitor’s maximum refresh rate. Start at three FPS below the refresh ceiling, then verify frametimes and latency in the games you actually play.
Turn G-SYNC off only when minimum possible latency matters more than tearing, your system can sustain frame rates well above the display’s refresh rate, and testing shows that the trade-off benefits you.
The best G-SYNC settings at a glance
| Setting | Recommended starting point | Why |
|---|---|---|
| Monitor refresh rate | Maximum stable refresh rate | Reduces refresh interval and gives VRR more headroom. |
| G-SYNC | On | Matches display refresh timing to GPU frame delivery within the VRR range. |
| NVIDIA Control Panel V-SYNC | On | Acts as a safeguard at the monitor’s refresh ceiling. |
| In-game V-SYNC | Off | Avoids stacking separate synchronization controls in the common G-SYNC setup. |
| NVIDIA Reflex | On, when supported | Coordinates CPU and GPU work for lower render latency. |
| Low Latency Mode | Off with Reflex; On or Ultra without Reflex, after testing | Reflex and the driver setting perform different jobs and should not be blindly stacked. |
| FPS limit | Refresh rate minus three FPS as a starting point | Helps prevent contact with the VRR ceiling. |
| Strobing | Off initially | ULMB, ELMB, DyAc and Pulsar require suitable frame rates and can introduce flicker or crosstalk. |
This is a balanced recommendation, not a universal competitive standard. A player who accepts tearing and wants the absolute lowest latency may prefer G-SYNC and V-SYNC off with very high or uncapped FPS.

A fixed-refresh monitor updates at regular intervals. If the GPU finishes a new frame while the monitor is scanning the previous one, parts of two frames can appear together as a horizontal tear. G-SYNC allows the monitor to vary its refresh timing so it can present completed frames when they are ready, provided the frame rate remains within the display’s supported variable-refresh range.
#1 Best Overall
- Samsung’s 32” Odyssey G5 QHD Gaming Monitor delivers brilliant visuals for exhilarating gameplay that’s more immersive than ever before.
- QHD resolution (2560 x 1440) boasts incredibly detailed, pin-sharp images.
- With a wide 178° viewing angle, the IPS panel consistently delivers crisp, clear hues from various viewpoints.
- 180Hz Refresh Rate and 1ms response time (GtG) allow fast reactions for ultra-smooth gaming, plus G-Sync compatibility syncs the GPU and panel to reduce choppiness, screen lag, and image tearing.
- HDR10 provides brighter highlights and nuanced shadows for added depth.
The result is generally smoother motion and less tearing when FPS changes. G-SYNC does not increase the game’s FPS, repair poor frametimes, reduce network latency, or make a slow panel respond faster.
NVIDIA’s G-SYNC setup documentation explains the relevant Control Panel configuration. The company’s monitor directory separates G-SYNC, G-SYNC Ultimate and G-SYNC Compatible products.
G-SYNC versus G-SYNC Compatible
G-SYNC monitors use an NVIDIA display module and traditionally offer a more controlled feature set, including features such as variable overdrive on supported models. G-SYNC Compatible monitors use an Adaptive-Sync implementation that NVIDIA has validated. They can work extremely well, but certification does not mean every model has identical overdrive behavior, VRR range, HDR performance, flicker characteristics or strobing support.

Two valid competitive configurations
1. Tear-free competitive play
- G-SYNC: On
- Control Panel V-SYNC: On
- In-game V-SYNC: Off
- Reflex: On when available
- FPS cap: Below the refresh ceiling
- Display mode: Exclusive fullscreen where practical; enable G-SYNC for windowed and fullscreen if using borderless mode
This configuration is usually the best starting point for players who dislike tearing, experience fluctuating FPS, or want smoother target tracking. The cap keeps the game inside the VRR range during normal operation, while driver V-SYNC provides a ceiling safeguard if the game reaches the monitor’s maximum refresh rate.
Latency can vary with the game engine, driver, presentation mode, frame limiter and Reflex implementation. “G-SYNC adds input lag” is therefore too broad. Compare the complete configurations rather than one toggle in isolation.

Exact setup path
Monitor and Windows
- Open the monitor’s on-screen display and enable Adaptive-Sync, VRR or G-SYNC, depending on its terminology.
- Temporarily disable incompatible fixed-refresh or strobing modes.
- Open Settings → System → Display → Advanced display in Windows.
- Select the correct monitor and choose its highest stable refresh rate.
- Confirm that the monitor is connected to the NVIDIA GPU rather than an integrated-graphics output.
NVIDIA Control Panel
- Right-click the desktop and open NVIDIA Control Panel.
- Go to Display → Set up G-SYNC.
- Select Enable G-SYNC, G-SYNC Compatible.
- Choose Enable for full screen mode, or choose Enable for windowed and full screen mode for borderless games.
- Select the intended monitor.
- Open Manage 3D settings → Program Settings and select the individual game.
- Set Monitor Technology to G-SYNC/G-SYNC Compatible where the option is exposed.
- Set Vertical sync to On for the tear-free configuration.
- Set Max Frame Rate to refresh rate minus three FPS if the game’s limiter is unreliable.
- Set Low Latency Mode to Off when Reflex is active. Without Reflex, try On first and test Ultra separately.
- Apply the changes and restart the game.
NVIDIA notes that the display may need to be the primary display and must use a compatible connection. If the option is missing, check the troubleshooting section below.
In-game settings
- NVIDIA Reflex: On, if available.
- V-SYNC: Off for the common driver-V-SYNC/G-SYNC configuration.
- Frame cap: Use the in-game limiter if its frametimes are stable; otherwise test the NVIDIA limiter or another reputable limiter.
- Graphics: Reduce settings that cause GPU saturation or unstable frametimes.
- Frame generation: Generally avoid for latency-focused competitive play unless you have tested the specific game and configuration carefully.
How to choose the FPS cap
The commonly used refresh-rate-minus-three rule is a starting point, not an NVIDIA guarantee or universal law.
| Refresh rate | Starting cap |
|---|---|
| 144 Hz | 141 FPS |
| 165 Hz | 162 FPS |
| 180 Hz | 177 FPS |
| 240 Hz | 237 FPS |
| 360 Hz | 357 FPS |
| 500 Hz | 497 FPS |
| 540 Hz | 537 FPS |
You may need a larger margin if the limiter overshoots, the monitor reports its ceiling inaccurately, the display is overclocked, or the game repeatedly touches the cap. Lower the limit until the frame-time graph and VRR behavior remain stable.
A stable 300 FPS can feel better than fluctuating 500 FPS on a 360 Hz display if the higher setting causes CPU spikes, thermal throttling or uneven frame delivery. Prioritize frame-time consistency, sustained FPS, input latency, image clarity and then peak benchmark FPS—in that order.
NVIDIA’s Max Frame Rate guidance discusses frame limiting, VRR operation and Low Latency Mode. Enthusiast testing and technical discussion are also available in Blur Busters’ G-SYNC 101 guide.

Reflex versus Low Latency Mode
NVIDIA Reflex is integrated into supported games and coordinates CPU and GPU work for just-in-time rendering. NVIDIA describes this pipeline in its Reflex documentation.
Low Latency Mode is a driver setting intended for games without Reflex. Start with On; test Ultra only when Reflex is unavailable and the game remains smooth. Ultra is not automatically better and can behave differently depending on whether the game is CPU- or GPU-bound.
With Reflex enabled, leave driver Low Latency Mode Off as a baseline rather than stacking two aggressive controls. Test Reflex Boost separately: it may maintain higher GPU clocks, but can increase power use, heat and fan noise.

- In NVIDIA Control Panel, enable Display → G-SYNC Indicator.
- Launch the game and confirm that the indicator appears.
- Change the FPS cap in a controlled scene and observe whether presentation follows the frame rate.
- Use a frame-time graph, not just an average FPS counter.
- Compare latency with and without G-SYNC using the same scene, cap, graphics settings and input routine.
The indicator confirms that G-SYNC is engaged, but it does not prove that the cap, V-SYNC, Reflex and presentation mode are optimal.
Refresh rate and motion clarity
A higher refresh rate shortens the interval between refreshes: 240 Hz is about 4.17 ms per refresh, while 360 Hz is about 2.78 ms. NVIDIA positions 360 Hz G-SYNC displays for competitive gaming in its 360 Hz overview. That does not mean 360 Hz makes reaction time 1.5 times faster.
The upgrade from 144 to 240 Hz is often more noticeable than the move from 360 to 500 or 600 Hz. A 600 Hz monitor running a game at 250 FPS cannot provide the full benefit of 600 Hz. Resolution, viewing distance, target size and sustained frame rate all matter.

Do not confuse:
- Refresh rate: How often the monitor can refresh.

- Pixel response: How quickly pixels change.
- Input latency: Time from input to visible response.
- Motion clarity: The combined result of refresh, response, persistence, strobing and frame pacing.
G-SYNC, ULMB, DyAc, ELMB and Pulsar
VRR smoothness and backlight-strobing clarity solve different problems. ULMB, ELMB and DyAc can make motion appear sharper by reducing visible persistence, but they generally need stable frame rates and a suitable refresh target. They may also reduce brightness, show crosstalk or flicker, and may not work simultaneously with the desired VRR mode.
NVIDIA describes G-SYNC Pulsar as variable-frequency backlight strobing intended to combine VRR smoothness with improved motion clarity. Availability and behavior depend on the monitor model. If motion looks worse, disable strobing, stabilize FPS and compare again.
Troubleshooting
G-SYNC is missing
- Connect the monitor directly to the NVIDIA GPU.
- Enable Adaptive-Sync or VRR in the monitor OSD.
- Install the correct NVIDIA driver.
- Use a compatible DisplayPort or HDMI connection.
- Set the display as primary where required.
- Check whether HDR, DSC, KVM or another monitor mode disables VRR.
- Verify that the exact monitor appears in NVIDIA’s certified directory.
The G-SYNC indicator appears, but tearing remains
- Lower the FPS cap by another 2–5 FPS.
- Use driver V-SYNC On and in-game V-SYNC Off.
- Test exclusive fullscreen.
- Disable strobing and HDR temporarily.
- Test another game to separate a game-specific issue from a display issue.
- Reset the game-specific NVIDIA profile.
What looks like tearing may instead be overdrive artifacts, strobing crosstalk or brightness pulsing.
Flicker or brightness pulsing
Large FPS swings, low-FPS operation near the bottom of the VRR range, OLED near-black behavior, HDR/VRR interaction and unstable overdrive can all contribute. Try a steadier cap, lower GPU-heavy settings, another overdrive mode and updated monitor firmware. If the issue persists, compare fixed refresh or another display.
Stutter after enabling G-SYNC
- Use one primary frame limiter instead of stacking several.
- Disable driver Low Latency Mode when Reflex is active.
- Lower CPU-heavy settings such as view distance, effects or simulation quality.
- Test a lower stable cap.
- Compare fullscreen and borderless modes.
- Consider shader compilation, asset streaming, overlays and capture tools as separate causes.
Black screens or borderless problems
Test exclusive fullscreen, confirm the selected GPU and refresh rate, and temporarily disable HDR, DSC, KVM and monitor strobing. If G-SYNC works fullscreen but not borderless, enable G-SYNC for windowed and full screen mode and check whether the game is using a different presentation path.
Recommended Free Tools
How to test your own best configuration
- Choose one repeatable game scene, training range or aim drill.
- Keep resolution, graphics, driver version, monitor mode and mouse settings unchanged.
- Compare G-SYNC On with a below-ceiling cap, G-SYNC Off with a high or uncapped frame rate, and any strobing mode separately.
- Record frame-time graphs, sustained FPS and visible artifacts.
- Repeat the same aim drill several times instead of judging one momentary impression.
- If available, use Reflex Analyzer with a compatible mouse, monitor and supported game configuration. NVIDIA’s Reflex Analyzer guide explains its requirements.
Reflex Analyzer measures the supported click-to-photon path; it is not a universal measurement of every source of system latency. An FPS counter also cannot reveal queueing, scanout timing, 1% lows or shader stutter by itself.

Monitor buying guidance
High-refresh G-SYNC Compatible monitor
This is the practical choice for most players. Evaluate the actual VRR range, response behavior, overdrive, input processing and warranty rather than assuming every certified model behaves alike.
240 or 360 Hz competitive sweet spot
These refresh rates offer a strong balance of latency, attainable FPS and image quality. They suit players who can sustain roughly the relevant frame rate in their main games without sacrificing too much resolution or visual quality.
500, 540, 600 or 610 Hz esports specialist
These displays make sense for dedicated FPS players with hardware capable of sustaining several hundred FPS and who prioritize motion clarity over resolution, HDR and general-purpose image quality. They are poor value if the game regularly runs below the target refresh rate.
Dual-mode OLED
A dual-mode OLED can offer high-resolution gaming alongside a lower-resolution, extremely high-refresh competitive mode. It is attractive for players who want one display for both competitive FPS and general gaming, but consider OLED burn-in policies, brightness behavior and price.
For current product discovery, use NVIDIA’s certified monitor directory. Manufacturer listings can change, and a monitor advertised with VRR is not automatically a hardware G-SYNC display. Dedicated esports alternatives such as ZOWIE’s XL2586X+ may prioritize high-refresh TN motion clarity without being G-SYNC products. Likewise, a dual-mode OLED such as ASUS’s ROG Swift PG27AQWP-G should be judged by its complete feature set, not only its G-SYNC Compatible listing.
The bottom line
For the best all-around competitive experience, use G-SYNC with driver V-SYNC On, in-game V-SYNC Off, Reflex On when supported, and a stable FPS cap below the monitor’s refresh ceiling. If tearing is acceptable and you can sustain FPS well above refresh, disable G-SYNC and synchronization for the lowest-latency alternative. The right choice is the one that produces stable frametimes, clear motion and better results in your own game—not the one with the most extreme setting.
