Despite this port/remaster being of low quality, it does play just fine on Proton with only video playback being an issue.
The game's video won't play on either stock Proton 9 or Proton Experimental.
This game has a Linux version as well. Both version work just fine, but the Linux version's performance suffered quite a bit at high resolutions.
This is the very first game I've played since Proton 7 where I was unable to get video playback working either on vanilla or Experimental Proton. Very strange. I opten for the latest version of GE Proton (version 9-13), and that fixed the issue. There aren't that many videos in the game, so it's not a huge issue, but it was still odd to see.
Works fine without problems with default Steam configuration.
You need to know how to use protontricks or use an alternative version of proton as proton GE
I use Steam base, not Tinker.
AMD RX 6xxx users: is necessary to have a kernel > 5.9 and updated Mesa libraries (ppa:oibaf maintains sufficiently updated libraries).
Current amd divers do not work with proton 5.13-4 and I have used proton 5.0-10 compatibility with protontrick for dotnet40 or just Proton-5.21-GE-1(recomended)
