Space Engineers 1 mostly just worked. Not great sim speed, even on a decently powerful system, but as long as the world didn’t get too complicated it was fine. Restarting the game from time to time helped.

SE2 on the other hand, I was unable to get to run.

Edit: I got my copy through Steam.

Edit 2 (2026-02-10): I solved the performance issues with SE on my system. I found non-Valve compatability tool called Proton GE. Runs pretty much perfect now using version 10-29. Installing the tool was pretty straight forward. Still no joy with SE2.
