| Cause | Explanation | |-------|-------------| | | Driver fails to respond within Windows timeout (2 seconds), compositor loses sync. | | Overclock/undervolt instability | GPU or VRAM overclocks cause micro-instability, breaking the real-time compositor loop. | | Corrupted SteamVR config files | steamvr.vrsettings or compositor.json have invalid entries (e.g., wrong resolution, legacy GPU settings). | | Conflicting background apps | Overlays (MSI Afterburner, RivaTuner, Discord overlay, NVIDIA ShadowPlay) hook into D3D and disrupt compositor. | | Multiple GPU / iGPU conflict | SteamVR tries to run on integrated GPU instead of dedicated GPU. | | Windows Mixed Reality (WMR) quirk | On WMR headsets (Reverb G2, Odyssey+), error 475 can appear after Windows update changes driver signing. | | Beta branch mismatch | SteamVR beta + graphics driver beta = unstable IPC handshake. |
