I try to play "Empyrion" on Linux via Steam. I have tried other games like "Satisfactory" without any issues and with a better performance as on Windows. But with Empyrion i get a max of 10 - 13 fps, where i have ~60fps on Windows on the same laptop. Graphic adapter is a nVidia 1050 GTX and OS is Arch Linux. If i remember correctly, Empyrion is a Unity game.
Yes, of course. But nothing helped really. There is a small difference between the used Proton version. With 8.25 GE i get 13 fps and with 6.4 GE1 i get 19 fps. Using PROTON_USE_WINED3D11=1
makes it more worse than ever, with only 5 fps.
Okay, I hadn't seen it mentioned in the post and was hoping that was all it would take. I have played it before, and I can't say I noticed any major issues like you're describing. I run an AMD card though, so that may make the difference on Linux.
I wish I had some other ideas, but ideas I've found on ProtonDB were always my best option. I will say that I've noticed performance issues on some Unity games previously. Whether it's from the engine or bad optimization I don't know though.
