SteamVR Beta Receives New Update

SteamVR Beta received another update yesterday to help developers working with the software and the Oculus Rift head-mounted display (HMD). A number of small updates have been launched for the platform over the past few weeks and this recent update is solely for the Oculus Rift.

OculusRift_7

Listed below are the current logs for the update:

Oculus driver:

  • Updated to OVR SDK 0.6.0.1
  • Hooked up Oculus compositor in direct mode when going through SteamVR’s compositor interface.

Known issues with Oculus direct mode:

  • The OVR service often does not give focus properly. In this case, the headset will display a black screen, but the companion window tracking will appear fine (or perhaps updating really slowly). The most reliable workaround appears to be launching the Demo Scene from the Oculus Configuration Utility and then closing it once it comes up.
  • CPU/GPU parallelism is lost.
  • Frame timing display shows solid-blue. Switching to raw reveals blocking on ‘distort cpu’. This is from the call to ovrSubmitFrame and is what is killing the cpu/gpu parallelism.
  • Uses considerably more gpu memory as everything is double buffered.
  • ‘distort gpu’ is a bit higher as it includes a bit more functionality (e.g. timewarp, overdrive, etc.).
  • Grid is missing its horizontal lines.
  • High quality overlay is not supported (falls back to rasterized quad mode).

VRFocus will continue to follow any further news on the SteamVR platform and report back.
