Anti-Aliasing (Performance Trick)
| Setting | Location | Value |
|---|---|---|
| MSAA | In-game | Low |
| MFAA | NVIDIA Control Panel (game profile) | Enabled |
Result: Visual quality comparable to MSAA Medium, performance cost of MSAA Low.
How it works
MFAA (Multi-Frame Anti-Aliasing) alternates AA sample patterns across consecutive frames. When combined with in-game MSAA, it effectively doubles the apparent sample count without doubling the rendering cost. The temporal nature of MFAA smooths edges across frames.
NVIDIA Control Panel Setup
- Open NVIDIA Control Panel
- Manage 3D Settings → Program Settings
- Select or add
AMS2AVX.exe - Set "Multi-Frame Sampled AA (MFAA)" → On
Refresh Rate & Display Settings
| Setting | Location | Value | Notes |
|---|---|---|---|
| Refresh Rate | Pimax Play | 72 Hz | Prioritizes stable frametimes over high refresh |
| Brightness | Pimax Play | -1 | Reduces eye strain on OLED panel |
| Contrast | Pimax Play | -1 | Better dark detail, less crushing |
| Exposure Compensation | In-game (Video Settings) | 0.90 | Tames overblown highlights |
Graphics Settings (72 Hz @ 6200×6200)
These settings target stable 72 Hz at full 50PPD resolution.
| Setting | Value | Notes |
|---|---|---|
| Shadows | Medium | Major performance saver |
| Reflections | Medium | Minor visual loss, big FPS gain |
| Particle Density | Medium | No noticeable difference in VR, frees headroom |
| Grass | High | Can drop to Low for 90 Hz |
| Everything else | High–Ultra | Mix to taste |
Running 90 Hz at 6200×6200 is brutal. Drop Grass and Particle Effects to Low first — they're the biggest gains with least visual impact in VR.
Particle and grass settings still being fine-tuned. Your mileage may vary depending on track/weather.
Other Recommended Settings
| Setting | Value | Notes |
|---|---|---|
| Render resolution | Native (6200×6200) | Let Pimax handle supersampling |
| Motion Smoothing | Off | AMS2 handles reprojection poorly |
| Runtime | OpenXR via OpenComposite | AMS2 is OpenVR-native; use OpenComposite to translate to OpenXR |
OpenComposite Setup
AMS2 uses OpenVR (SteamVR) natively, not OpenXR. To bypass SteamVR and run directly on Pimax's OpenXR runtime, use OpenComposite:
- Download OpenComposite (64-bit DLL)
- Extract to AMS2 install folder
- Run
OpenComposite.exeor copy the DLL override
OpenComposite translates OpenVR calls → OpenXR, giving you the performance benefits of native OpenXR without SteamVR overhead.
Used only for performance overlay (FPS + GPU/CPU bound indicator). No visual tweaks enabled — no sharpening, no Toolkit foveated rendering.
