CtrlAltStudio updates to Oculus SDK 0.6

CAS-logoOn Saturday, October 3rd, the Oculus Rift supporting CtrlAltStudio viewer updated on Windows to version 1.2.5.43397.

The release sees the viewer reach parity with the Oculus SDK 0.6. However, it is not at this point being regarded as a “formal” release, as David Rowe, the viewer’s developer, notes that it requires additional user testing.

David lists the other changes of note with the release as being:

  • The viewer works in both direct and extended Rift display modes
    • If using extended mode you no longer need to drag the viewer onto the Rift’s screen before toggling into Riftlook view
    • If you switch between direct and extended Rift display modes, you’ll need to restart the Oculus Configuration Utility and the Oculus VR Runtime Service.
  • Advanced Lighting Model no longer needs to be enabled in order for Riftlook to work
  • The hardware cursor used in previous versions has been replaced with a basic cross hair software cursor. It may not look pretty but it should still work as before
  • There’s a new “Mirror Rift display to desktop” option in Preferences > Graphics > Display Output
  • The scale of the UI depth Display Output option has been altered to work with the updated Rift rendering
  • A “Mirror Rift display to desktop” Display Output option has been added
  • The following Display Output options, which are no longer available in the Rift SDK,have been removed from the viewer: Timewarp, Timewarp waits, V sync, and Pixel overdrive
  • If you install over the top of a previous version you’ll probably want to press the “Reset” button for the “UI depth” Display Output option.
The 1.2.5.43397 updates sees the removal of the Timewarp, Timewarp waits, V sync, and Pixel overdrive from Preferences > Graphics > Display Output, and the addition of a new Mirror Rift display to desktop option
The 1.2.5.43397 updates sees the removal of the Timewarp, Timewarp waits, V sync, and Pixel overdrive from Preferences > Graphics > Display Output, and the addition of a new Mirror Rift display to desktop option

As always, for a full list of changes and updates, please refer to the release notes.

David also goes on to note:

I can achieve a pretty smooth 75 FPS experience on the Rift if the scene’s not too complex, though only if I have my main monitor set to 120Hz. If I set it to 60Hz I only get a somewhat juddery 65 FPS on the Rift. I haven’t looked into this yet and am keen to hear how other people get on. Note: You can use Ctrl+Shift+1 to display a statistics window in Riftlook.

The release doesn’t see the viewer updates to a more recent Firestorm code base than 4.6.9, and there is no corresponding Mac release at this time.
