Looks like Warzone is one of the unfortunate ones, the kernel level anti cheat currently stops it from working on Linux.

Reka (added to my wishlist 😄) seems to run well. If it will run straight out the box or not seems to be a little hit and miss. You can check any troubleshooting steps on protondb. This shows Linux isn’t quite at the “it just works” stage. But for this title if you do run into an issue it seems like an easy fix.

Cyberpunk runs really well. I haven’t had to tweak anything for my install.
