1 year agoCompatibility with old games on linux is great, much better than it is for newer games. Those 2010 and earlier (all the way back to windows 95 or so) games that have trouble on Windows 10 generally work better on Linux than on Windows 10.
For dos games you’d use dosbox on both Windows and Linux so the experience is mostly identical.
You also get quality of life stuff such as: if a game starts at 640x480 on your 4k monitor, it doesn’t change your desktop resolution to 640x480, it just gets scaled up to the full screen.
Specifically check out the Lutris software: it has integrations to install and run your old games from GOG or the original discs onto Linux.
if you are having weird bugs when playing via Proton, report the issue on the Proton GitHub page. If it’s a graphical glitch you can also report it to proton-vkd3d or DXVK depending on which one is being used by the game. If unsure just report it only to Proton.
The Proton developers and the developers of associated projects (DXVK, vkd3d, etc) will often add workarounds into the various parts of the Proton platform to get a game to work correctly, even if the problem you are seeing is a game bug or driver bug.
