Configure G-SYNC for MSFS 2024 with the correct NVIDIA V-Sync, display mode and FPS cap, plus fixes for tearing, flicker and stutter.
To configure G-SYNC for Microsoft Flight Simulator 2024, enable Adaptive-Sync on the monitor, enable G-SYNC for windowed and full-screen applications in NVIDIA Control Panel, set driver V-Sync to On, leave the simulator’s V-Sync Off, and cap frame rate two or three FPS below the display’s maximum refresh rate.
This configuration applies to the Windows PC version running through an NVIDIA GPU and a G-SYNC or compatible Adaptive-Sync display. Console VRR and VR-headset refresh control work differently and are not configured through NVIDIA Control Panel.
How do I set up G-SYNC for MSFS 2024?
- Enable Adaptive-Sync on the display. Open the monitor or television’s on-screen menu and enable its Adaptive-Sync, Variable Refresh Rate or G-SYNC Compatible option. Connect it to a GPU port that supports VRR at the required resolution and refresh rate.
- Select the highest refresh rate in Windows. Open Windows display settings, choose the MSFS monitor under advanced display settings and select its intended maximum refresh rate. A 144 Hz monitor left at 60 Hz gives G-SYNC a 60 Hz ceiling.
- Enable G-SYNC in NVIDIA Control Panel. Under
Display > Set up G-SYNC, tickEnable G-SYNC, G-SYNC Compatible. SelectEnable for windowed and full screen mode, choose the correct monitor and enable settings for that display if the additional checkbox appears. The windowed option matters because MSFS 2024 can operate through a borderless-style full-screen presentation. - Create or select the MSFS 2024 profile. Open
Manage 3D settings > Program Settingsand select Microsoft Flight Simulator 2024. SetMonitor Technologyto G-SYNC or G-SYNC Compatible if shown,Preferred refresh rateto Highest available,Vertical syncto On andMax Frame Rateto an appropriate cap. Avoid changing Global Settings unless every game should inherit these values. Our recommended NVIDIA profile values for MSFS cover the surrounding options without applying unnecessary overrides. - Turn off V-Sync inside MSFS 2024. Use the simulator’s normal full-screen or borderless display mode on the G-SYNC monitor, but leave its own V-Sync disabled. If Frame Generation makes that control unavailable, keep the NVIDIA driver’s V-Sync setting enabled instead.
- Restart the simulator. Driver-profile changes are most reliable when MSFS 2024 is closed and reopened. A Windows restart is not normally required.
What FPS cap should I use with G-SYNC?
Set the cap two or three FPS below the top of the monitor’s variable-refresh range, preventing MSFS 2024 from repeatedly striking the fixed-refresh ceiling. These values are sensible starting points:
| Display refresh rate | Starting FPS cap |
|---|---|
| 60 Hz | 57–58 FPS |
| 75 Hz | 72–73 FPS |
| 120 Hz | 117–118 FPS |
| 144 Hz | 141–142 FPS |
| 165 Hz | 162–163 FPS |
| 240 Hz | 237–238 FPS |
If the monitor has a lower documented VRR ceiling than its nominal refresh rate, base the cap on that ceiling. If output still touches the maximum during light scenes or menus, lower the limit by another one or two FPS. We explain the available driver and simulator methods in our MSFS 2024 frame-rate limiting guide.
Frame Generation can make FPS counters confusing because the generated output rate is higher than the base rendering rate. Judge the cap against displayed output FPS. If NVIDIA Reflex already holds the output safely below the refresh ceiling, do not stack another limiter on top; competing limiters can create uneven frame pacing.
Should V-Sync be on or off with G-SYNC?
Use V-Sync On in NVIDIA Control Panel and Off inside MSFS 2024. While frame rate remains below the cap, G-SYNC controls the display timing; driver V-Sync acts as a safety net at the upper boundary and prevents tearing if the ceiling is reached.
Do not select Fast Sync for this arrangement. Leaving V-Sync off in both places can produce a tear near the bottom of the screen, while enabling it in the simulator can add an unnecessary second layer of frame control. Our detailed explanation of MSFS V-Sync behaviour covers cases where G-SYNC is not being used.
How can I tell whether G-SYNC is working?
The clearest check is NVIDIA Control Panel’s temporary G-SYNC Indicator, available from its Display menu on supported configurations. Launch MSFS 2024, focus the simulator window and confirm that the indicator appears.
A monitor with a live refresh-rate readout offers another useful check: its reported refresh should move with the simulator’s delivered frame rate instead of remaining fixed. Smooth camera movement without a horizontal tear is supporting evidence, but it is not conclusive because an ordinary V-Sync configuration can also hide tearing.
Why does MSFS 2024 still tear, flicker or stutter?
G-SYNC corrects refresh mismatches; it does not remove every source of poor frame pacing in Microsoft Flight Simulator 2024.
| Symptom | Likely cause and fix |
|---|---|
| The G-SYNC setup page is missing | Enable Adaptive-Sync in the display menu, verify that the cable and port support VRR, and confirm that the display is connected to the NVIDIA GPU. On a laptop, an internal screen routed through integrated graphics may require a supported dGPU-only or MUX mode. |
| Tearing near the refresh ceiling | Confirm that driver V-Sync is On, lower the FPS cap slightly and check that MSFS is running on the G-SYNC display rather than a second monitor. |
| The indicator does not appear | Select windowed and full-screen G-SYNC, confirm the correct display and application profile, then restart MSFS. Test with the simulator window focused. |
| Brightness flicker | Some displays flicker when frame times fluctuate around the lower VRR boundary. Reduce demanding settings to keep FPS steadier, try full-screen-only G-SYNC, or disable G-SYNC for MSFS if the panel’s behaviour remains distracting. |
| Stutter without tearing | CPU main-thread limits, scenery loading and abrupt frame-time spikes remain visible through G-SYNC. If Developer Mode reports a CPU bottleneck, use our steps for reducing main-thread limitation rather than changing VRR settings. |
| Frame rate is stuck at 30 or 60 FPS | Check for an in-game V-Sync limit, a second frame limiter or a Windows refresh rate left at 60 Hz. Keep only one intentional FPS cap. |
Below the display’s minimum VRR rate, compatible monitors may use low-framerate compensation by repeating frames. That can preserve synchronisation, but it cannot make a low or unstable base frame rate feel like genuinely smooth rendering.
