Does Iracing Support Gsync

Answers ‘does iracing support gsync’ for iRacing drivers. See if G-SYNC works, why issues occur, and quick steps to enable or troubleshoot for tear-free racing.

If you’re asking “does iracing support gsync”, short answer: yes — iRacing works with G-SYNC, but you must enable it in your GPU/monitor settings and avoid conflicting sync options inside the sim. You’re in the right place to fix tearing fast.

Quick Answer: does iracing support gsync

Yes. G-SYNC is a monitor/driver feature (NVIDIA) and iRacing will benefit from it. For best results run iRacing in exclusive fullscreen or enable G-SYNC for windowed mode, turn off in-sim V‑Sync, and cap FPS appropriately.

What’s really going on

G-SYNC is a variable refresh-rate technology from NVIDIA that syncs your monitor’s refresh rate to the frames your GPU outputs. Games don’t need to “support” it directly — they just need to let the GPU/monitor control timing. iRacing will display frames normally, but problems appear when iRacing and your driver both try to enforce vertical sync (V‑Sync) or when frame rate exceeds your monitor’s range. That’s why you can have tearing or stutter even when G‑SYNC is available.

Step-by-step fix

  1. Update drivers and firmware: install the latest NVIDIA drivers and update your monitor’s firmware if available.
  2. Enable G-SYNC in NVIDIA Control Panel: open NVIDIA Control Panel → Display → Set up G-SYNC → enable for full screen (and check “windowed and full screen” if you use borderless). Apply.
  3. Set iRacing to exclusive fullscreen: in iRacing options use Fullscreen mode (not borderless/windowed) for the most reliable behavior.
  4. Turn off iRacing V‑Sync: in iRacing graphics settings disable any Vertical Sync option to avoid double-syncing.
  5. Cap your framerate: set a frame limit at or slightly below your monitor’s max refresh (e.g., 1–2 FPS under 144Hz) to prevent hitting the top end where G‑SYNC hands off to V‑Sync and causes stutter. Use iRacing’s frame limiter or an NVIDIA limiter.
  6. Test on-track: run a few laps and look for tearing or stutter. If you still see issues, repeat step 2 but enable G‑SYNC for windowed mode and switch to borderless if you prefer overlays.

Extra tips / checklist

  • If using AMD FreeSync, the same idea applies—FreeSync works but enable it in Radeon settings.
  • Avoid enabling both G‑SYNC and in-sim V‑Sync — that causes extra input lag or micro-stutters.
  • If you use motion smoothing tools (NVIDIA Reflex, LC, or 3rd-party frame limiters), check interactions — disable extras while troubleshooting.
  • If your FPS drops below monitor’s G‑SYNC range, you’ll still get stutter; aim for steady FPS or use a slightly higher refresh monitor.
  • Use an on-screen FPS counter (Steam, RTSS, or iRacing) to confirm frame rate and fine-tune the cap.

FAQs

Q: Will G‑SYNC add input lag in iRacing?
A: Properly configured, no noticeable extra lag. Avoid double V‑Sync and use exclusive fullscreen for lowest latency.

Q: I use borderless windowed on a second monitor — will G‑SYNC work?
A: Only if you enable “G‑SYNC for windowed and full screen” in NVIDIA Control Panel. Fullscreen is still more consistent.

Q: Does iRacing require any special setting to enable G‑SYNC?
A: No special iRacing setting. Just disable iRacing V‑Sync, enable G‑SYNC in NVIDIA settings, and cap FPS as needed.

Q: What if I still see tearing at high FPS?
A: Cap your FPS a couple frames below the monitor refresh or enable V‑Sync only after capping (less ideal). Update drivers and try exclusive fullscreen.

Wrap-up

G‑SYNC works with iRacing — it’s a GPU/monitor feature you enable outside the sim. Update drivers, enable G‑SYNC, run fullscreen, disable in‑sim V‑Sync, and cap FPS. If problems persist, toggle “windowed” G‑SYNC in NVIDIA Control Panel and re-test.
