I also play Automobilista 2 and use the oculus mode as you’ve started.
However I can still use oculus mode though with a different method.
create a shortcut to C:\Program Files\Pimax\Plugin\OCSupport\OVR_Launcher_x64.exe
and then add the following argument to the target:
G:\Steam\steamapps\common\Automobilista 2\AMS2AVX.exe -useoculussdk
Obviously change the G:\ to wherever your steam installation is
So in my case the Target will read:
“C:\Program Files\Pimax\Plugin\OCSupport\OVR_Launcher_x64.exe” G:\Steam\steamapps\common\Automobilista 2\AMS2AVX.exe -useoculussdk
that’s all in 1 line with a space between the …64.exe" and the G:\steam…etc
