In-Game VR Settings
| Setting | Value | Notes |
|---|---|---|
| VR Mode | Foveated | Uses eye tracking to render periphery at lower res — massive perf gain |
| MSAA | 4x | Good balance of clarity vs performance |
| Number of Lights | 0 | Disables dynamic car lights — big FPS saver in night races |
| Runtime | OpenXR | Set Pimax as OpenXR runtime in Pimax Play |
Why Foveated + Eye Tracking
iRacing's foveated rendering uses your eye position (from the headset's eye tracker) to:
- Render full resolution only where you're looking
- Reduce resolution in peripheral vision (where you won't notice)
This cuts GPU load significantly without perceptible quality loss. Requires eye tracking enabled in Pimax Play but Quad Views disabled — they don't play nice together.
With foveated rendering enabled, 90 Hz is achievable without heavy tweaking — unlike AMS2 which struggles at that refresh rate.
OpenXR Toolkit
Used only for performance overlay (FPS + GPU/CPU bound indicator). No visual tweaks enabled.
