SteamVR:

• Added per-app settings for overriding automatic throttling and prediction behavior. This is useful for applications with particularly poor performance that benefit instead from a fixed lower framerate for an overall smoother experience (e.g. sims). Note: These settings are only available to headsets which use SteamVR’s compositor (e.g. Index, Vive).
  
• Allow motion smoothing to apply up to six frames of extrapolation (was three). Note: This also only applies to SteamVR’s compositor.
  
• Disabled the HTTP request to check for updates when SteamVR is running without Steam.
  

OpenXR:

• SteamVR now passes all OpenXR 1.0 conformance tests on Windows for Vulkan, OpenGL, D3D11, and D3D12.

Note: Some users with NVIDIA GPUs are experiencing dropped frames with SteamVR 1.15. If you encounter this issue on a 10xx or 20xx card, consider rolling back your GPU drivers to 446.14. This resolved the issue for many people.
