This article contains some helpful tips about how to use Oculus Rift with Doomsday.
The Apply Desktop Settings button will restore desktop default settings.
Oculus Rift is supported in the binary packages for Windows and OS X. On other platforms, you'll have to compile Doomsday yourself using the Oculus SDK. (Set
LIBOVR_DIR in your qmake config or config_user.pri.)
(LibOVR 0.4.2) Doomsday works best (only?) in the “extended desktop” mode. The game window is automatically moved to the HMD screen when the Oculus Rift VR mode is enabled. The game window is moved back to a regular monitor when the VR mode is changed back to “no stereo”.
You must move the game window to the HMD screen manually. The easiest way to do this is to use the duplicate monitor mode. Make sure the window is in fullscreen mode (F11).
In version_1.15, the UI adapts automatically to be a good size for Oculus Rift.
In version_1.13, there is no support for alternative UI styles, so you'll have to manually adjust the font sizes to suit Oculus Rift. The best way is to increase font sizes with the command line option:
While Oculus Rift is connected, an auto-configuration button (“Apply Rift Settings”) is shown in the 3D & VR Settings dialog. This will set a bunch of cvars to values that work better on the Rift. Most importantly, the auto-configuration will ensure you have the appropriate head tracking input bindings:
bindcontrol lookpitch head-pitch bindcontrol yawbody head-yaw
For a good experience on the Oculus Rift, make sure you'll keep the FPS at 60.
Disabling the Bloom effect helps a lot if your GPU is struggling with fill rate.
In version_1.15, you can adjust the Oculus Rift frame buffer pixel density in the 3D & VR Settings dialog. Reducing density will improve rendering performance, however this will reduce image quality.
