The open source measurement tool on github OCAT turned version 1.2 and supports now all major VR devices with an overlay in HMDs.

Anybody into measuring performance of VR should have a look at OCAT and give it a try. System requirements are Windows 7/10 in 64bit.

  • Statistics support for WMR applications via PresentMon
  • Custom ETW logging for SteamVR and Oculus compositor providers
  • New configuration to disable event logging for VR compositors
    • Read Capture Config
