Yes I am. I appreciate the help though. It seems pretty clear that it's failing to recognize the gamescope argument because even if I use it barebones without any resolutions or FSR arguments it still fails to launch. Wish I could see thr output somewhere so I could know what to look into.
That said, I have since looked into Nobara and Bazzite and they look really promising. They should have all this stuff I'm trying to do baked right in. The point still stands though that these are extra complications that I wouldn't have on Windows with a full driver suite.
