I recently found about about Proton aka Steam Play, which is basically Valve's custom fork of WINE with built-in support from the Steam UI, so I thought I'd give SiS a try on my Ubuntu-MATE 18.04 system. Aside from red giants not displaying correctly, it seems to work pretty well!



The only issue I encountered was that red giants seem to render strangely. Everything else seems to work fine, though I haven't seen all of the weapon effects in combat yet. Coilgun/laser/missiles effects seem to display fine, so I don't see why any of the others would have issues, but you never know.

Cool. What's your graphics adapter?

I'm using a Radeon HD 6520G.

Edit: I should probably add that I'm using the Mesa open-source driver. I've tried the official AMD drivers for Linux and I've had nothing but problems with them. Well, more problems than I've had with Mesa, but I suppose that's the best I can ask for when it comes to Linux graphics support :/
