NOTES: Warhammer 40K Space Marine Master Crafted Edition does not launch on SteamOS with any Proton or configuration I tried and would result in a BugSplat error message whenever I launched the game.

We can play the game on Dual Boot Windows, although the game performance is not very good and barely manages to keep 30FPS at times.

I highly recommend playing the original Space Marine which runs at 90FPS Max settings on the Steam Deck OLED instead of this Remaster in it’s current state.
