I'm attempting to follow the instructions to get my TF2 to work with my Oculus rift. I've added "-vr" to the launch command line, and it splits the screen in half when I start a game. However not in the 2 fish-eye views that are expected with the Oculus. The "vr_configuration" command appears as an option in the console but typing it in while on the main menu does nothing. The console also does not appear to recognize many of the convars listed on the user guide.
