Stereoscopic rendering - 3D
Stereoscopic 3D is included in Racer v0.9.0RC6. It is currently limited to nVidia Quadro cards (unless AMD cards can take over transparently). 3D Vision (from nVidia) may follow later, possibly. Also interesting and hopefully easy to implement is support for the Oculus Rift, which should be more immersive than watching a (severely FOV-limited) monitor.
Currently only nVidia Quadro's are supported. This is really a choice from nVidia, to not support it on Geforce (consumer) type cards. This is not expected to change anytime soon. The nVidia cards can operate in quad-buffer, meaning 2 front and 2 back buffers are available. Racer renders 2 slightly different views for each eye. The graphics card does the swapping and synchronizing of the (active) shutter glasses.
nVidia seems to have the following stereo technologies:
Next to this, for 3D Vision (any variant) you'll need an approved 120Hz monitor, which can be found on the nVidia website (click to visit their webpage). 3D Vision 2 monitors support LightBoost, which tries to overcome the fact that most 3D glasses make the image darker. For quad-buffer, you can use any 120Hz monitor, it seems. Even 60Hz monitors will do, but as you only get 30Hz per eye, it's not pretty to watch. However, it can be used for testing purposes. Expect a lot of ghosting in that case though.
These settings in racer.ini affect stereoscopic rendering:
