SteamVR is Valve’s platform for running virtual reality applications on PC. It provides hardware-agnostic runtime services, device drivers, and developer tools so VR headsets, motion controllers, and tracked peripherals can work with VR games and apps.
Key points:
- Compatibility: Works with many headsets (Valve Index, HTC Vive, Meta/Oculus via OpenXR, Windows Mixed Reality, and others) through Steam and OpenXR support.
- Runtime & compositor: Manages VR rendering, headset tracking, asynchronous reprojection, and the compositor that submits frames to the headset.
- OpenXR support: Modern SteamVR versions support OpenXR, the cross-vendor VR API standard, so apps written to OpenXR work across headsets.
- SteamVR Home and Dashboard: Provides a customizable home environment and an in-VR overlay/dashboard for launching apps, settings, and notifications.
- Input system: SteamVR Input lets developers map controller bindings to actions, supporting many controller types without per-device code.
- Room-scale & tracking: Supports seated, standing, and room-scale experiences using Lighthouse base stations, inside-out tracking, or external trackers.
- Performance tools: Includes reprojection, motion smoothing, and tools like SteamVR Performance Test and frame timing graphs to help diagnose performance issues.
- Developer tools: SteamVR SDKs, sample scenes, and support in engines like Unity and Unreal for building VR apps.
