Luxtorpeda doesn’t support many games, but it’s pretty great for all the games it works for.

For anyone unfamiliar with the project, you can select it as an alternative to proton for a game, and for any supported games it will download open source projects that replace the original engine/client for the game. For example selecting it for Morrowind will run Morrowind through the OpenMW project, which gives a much better experience than the original game engine.

Here’s a list of all the supported games. There’s also sister projects Boxtron for running DOSbox games, and Roberta for running adventure games through ScummVM. All should be available to download through ProtonUP-qt, which is available on the discover store.
