So I'm getting this error while trying to play Mechwarrior 5 on Steam. I'm on Ubuntu, running a GTX 980, and my current driver according to Nvidia Server X is 525.85.05.
I have tried with Proton Experimental, Proton 7.0, and GE Proton 7.50.
The only way I've made it to the main menu is using the "PROTON_USE_WINED3D %command%" launch command, but the game runs at a painful 1fps in the menu for a few seconds, and then it crashes.
Any help would be appreciated!
