Hey N8128 thanks for the hints
I found on my side that when i use the stereo on in console command the light on my headset (dk2) is turning yellow and the screen is not responding it freezing what the hell !??
edit: By the way… in vr preview it work well.
Other thing… is there a way to make the hmdwarp s=13 cmd to be fonctionnal in the 4.9 ? Can’t seem to work consoledev on or hmdwarp 1=1 either.
