Awh, doesn't work, even under Proton-GE on Linux
Sure does—just need to install some required DLL files using protontricks. Specific list in this Reddit thread: https://reddit.com/r/SteamDeck/s/Hu6X0Y9hR6
Wild. The Linux version didn't work because it's openly missing some linked libraries that they forgot to ship, I'm surprised that proton won't auto-figure the need for d3d*, likewise it's frustrating that the PROTON_LOG doesn't scream about this. Regardless, thanks anyway. I had basically given up on getting this running.
