Luxtorpeda is a very interesting project. It's a compatibility layer (like Proton) but designed to help you run Native Linux game engines for various Steam games.
Why? Well, quite a number of games on Steam actually have much more modern community-made game engines, that can give all sorts of quality enhancements. Luxtorpeda allows you to easily download these and run them directly through Steam.
Version 63 was recently released and here's the main technical changes:
- Switch to using Steam Linux Runtime - Sniper for the built engines. This provides newer tooling for builds, which should make future development easier, for example being able to build qt 5.15 and have gcc 10 available. The 100+ engines have been re-built. Note that previous clients should still work on the older soldier, but any new updates will only happen to sniper (this client and above). If you run into any issues with the engines, please open a new issue in the packages repo.
- Rust panics, if they occur, should now be caught and displayed in the Godot UI.
- [dreamer] Use steamlocate v2 alpha
- Bump h2 from 0.3.15 to 0.3.17
Aside from that, there's been numerous upgrades to the various game engines it offers up to help you get the most out of your gaming. You can see a full list of supported titles here, along with any notes on the supported status of each one and there's quite a lot now.
I previously did a guide on how to use it, and while focused on the Steam Deck the same applies to using it on a Linux desktop:
