Had to lower the resolution to stop menu flickering and lower graphical settings to not run out of video memory when loading a new game.

I never got the opengl error that everybody mentions concerning this game engine so a patched version of proton seems unnecessary with the newest version. With the default game settings the game would flicker a lot and wouldn't load a new game. Lowering the resolution seemed to fix that but when loading a new game the program would crash with an error complaining about having run out of video memory. The error may be due to the weak integrated GPU but lowering the graphical settings fixed the problem and I am now able to launch a new game.

Judging from the steam reviews of the game it is running remarkably well on this little potato but since this is my first CM game I have absolutely no idea how to play the actual game so there is always a chance I missed some minor anomoly.
