WiVRn with xrizer: All I had to do was set the headset resolution down to about 85% and then tweak some in game graphical settings and it looks and plays fantastic. Proton GE 10-10 WiVRn on envision with xrizer. The one problem I do see is that the inputs do not display properly. They just show a yellow exclamation mark triangle. playing with wivrn without xrizer resulted in buttons not working at all.
overall it is a fantastic experience on WiVRN
ALVR: I do not know what it is with ALVR on this game but I ticked the resolution and graphics down to the same as WiVRn however it just runs so much slower. I am sure with a bit more tinkering on my end I can get it there, but I feel it might be at some graphical costs.
