How to Configure Graphics in Iracing

Learn how to configure graphics in iRacing for stable FPS and crisp visuals. Fast, step-by-step settings, GPU driver tweaks, and quick fixes to stop stutter.

If you want to know how to configure graphics in iracing, the short answer is: set resolution/fullscreen, pick a render quality that gives you stable FPS, then dial back expensive effects (shadows, reflections, MSAA) until your frame rate is steady. You’re in the right place to fix it fast.

Quick Answer — how to configure graphics in iracing

Start in iRacing’s Options → Graphics. Choose your display and resolution, set Fullscreen, then adjust Render Quality (percent) until you hit a steady FPS close to your monitor refresh. Turn off or lower shadows, reflections, and anti-aliasing if you don’t have enough GPU power.

What’s really going on

iRacing renders each frame to your graphics card. If settings are too high for your GPU or video memory, you’ll get low FPS, stutter, or inconsistent frame times. “Render Quality” scales how detailed the scene is. High settings look better but cost more performance. Your goal is consistent frame timing — smooth, predictable frames — not the absolute highest detail.

Step-by-step fix

  1. Update GPU drivers first. Use NVIDIA GeForce Experience or AMD Radeon Software and reboot.
  2. Open iRacing → Options → Graphics. Select your primary monitor and set the native resolution. Use Fullscreen (not Windowed) for lowest input lag.
  3. Set Render Quality to 100% to test baseline. Start a practice session and note FPS with the in-game FPS counter (press F9 if needed).
  4. If FPS is below your target (usually 60 or your monitor’s refresh), lower Render Quality in 10% steps and retest until stable.
  5. Reduce heavy effects: Shadows → Low/Off, Reflections → Low, Anti-Aliasing (MSAA) → Off or 2x. Texture and car detail can stay higher if VRAM allows.
  6. Cap your framerate: set iRacing’s max frame rate to your monitor refresh or slightly below (e.g., 144 → 143) to avoid micro-stutter. Leave V-Sync off if you have G-Sync/FreeSync.
  7. Tweak GPU control panel: set power management to “Prefer maximum performance,” turn off driver-level V-Sync if using adaptive sync, and enable low-latency/“Ultra” options if available.

Extra tips / checklist

  • Use the iRacing FPS overlay to check consistency (not just peak FPS).
  • For multi-monitor or triple-screen rigs, lower Render Quality first — resolution eats VRAM.
  • VR users: prioritize frame rate over look — drop shadows, reflections, and post-processing.
  • If you still stutter, check CPU usage; a weak CPU can bottleneck even a strong GPU.
  • Consider a clean reinstall of GPU drivers (Display Driver Uninstaller) if strange artifacts persist.

FAQs

Q: What Render Quality should I use for 60 FPS?
A: Start at 100% and lower by 10% until you get stable 60 FPS. Many mid-range GPUs need 70–90% at high resolutions.

Q: Should I use fullscreen or borderless window?
A: Fullscreen gives the best performance and lowest input lag. Use borderless only if you frequently alt-tab.

Q: Why does iRacing stutter even with good FPS?
A: Stutter can come from inconsistent frame times, CPU hiccups, background apps, or driver issues. Close background apps and check frame time graph.

Q: Is MSAA worth it?
A: MSAA smooths edges but is costly. Try FXAA (in-game post-processing) or a low MSAA level if you need clarity without big performance loss.

Short wrap-up

The fastest fix is: update drivers, use Fullscreen, set resolution to native, then lower Render Quality and expensive effects until your FPS is steady. Test in practice, tweak settings a little each session, and you’ll find the balance between visuals and smoothness.
