- Enable Eye Tracking in PimaxClient.
- Calibrate Eye Tracking in PimaxClient.
- Enable “PimaxXR” in “PimaxXR - OpenXR Control Center”.
- “Allow use Eye Tracker” in PimaxXR - OpenXR Control Center.
- Enable Eye Tracking in in-sim menu of OpenXR Toolkit.
- Enable Foveated Rendering in in-sim menu of OpenXR Toolkit.
- Play with OpenXR Toolkit Foveated Rendering Presets.
- Expect circa 10% FPS increase due to Foveated Rendering (no matter Fixed or Dynamic) in MSFS.
- Expect some shimmering at the edges of DFR circles.
- Don’t expect DCS/QuadViews-level FPS increase.
With 4090, enabling FFR gave me 10% FPS increase. Switching from FFR to DFR alone provides no FPS increase. DFR theoretically allows usage of more aggressive FR settings in OXRT for 4% more FPS increase, but I returned to FFR due to shimmer at the edges of the FR circles, visible when the FR circles are moving with the gaze (ET).
