So, for example, to run Portal 2 without the Razer Hydra, I have to run it from the command line and specify -nosixense there.
For Team Fortress 2, running from the command line gives you an error about the game txt file. So it's not possible to specify -vr there either.
The only way I could get TF2 to run with command line options (and thus to enable VR), was to make a shortcut like this:
Code: Select all
C:\steam\Steam.exe -applaunch 440 -nointro -vr
I don't know if anyone else's steam is bugged like that. But if it is, maybe that will help you.
