Found this in another thread and it worked :
Just found a workaround for the time being. On the game page in your library, click on the cog icon, then properties, then down in launch options, paste this.
force_compat_profile=true %command%
With this, I can get past the first logo into gameplay. There was a popup in the top left about some kind of warning, don’t really know, but it went away after a bit so I didn’t really pay much attention to it.
I just bought it, booted with proton experimental, on the SD, didn’t work… crashes every time. Original one works like a charm.
I’m going to pick up reflex thank you!
Sounds easy enough, I’ll give it a try tonight! Thanks!
