Hi! Absolutely none game with Steam Proton doesn't works! But when I use Wine-GE with Lutris (or just use Wine-GE instead of Steam Proton) - everything works fine! Where's the issue may be? 🤔

But for example I've try to launch a game through Steam Proton 8.0-5 via Steam from Flatpak now. How can I find here required libraries?

OHH you're using flatpak!

Have you configured flatseal to allow steam access to your "/usr/lib/*"?

I didn't notice any libraries failing to pull but you should give steam access there anyway to help get your Linux native games running easier. Allowing steam access outside its own container should fix most issues, but it doesn't look like it will fix this one.

Additionally, I noticed issues with msaa happening, are you using an Nvidia GPU by chance? If so, I recommend Opening the Nvidia x-config app and overriding antialiasing and forcing 4x or 8x fxaa instead of msaa. Msaa is borked on Nvidia, renders basically any game using it unplayable.

Took me weeks to get Cities Skylines 2 working until I stumbled upon that accidentally.

Yeap!
