For those who don’t know, Luxtorpeda is a compatibility tool that can take the place of proton for supported games. Proton works by letting windows games run on Linux, but Luxtorpeda instead works by downloading replacement linux engines for the games and running them through that instead.
For example, the game Morrowind has an excellent engine replacement called openMW that works natively on Linux. You can download Morrowind on steam, set the compatibility tool to be Luxtorpeda, and when you first launch the game it will download and install openMW. After that it will run the game through openMW with all the benefits that brings.
It’s especially nice on platforms like steam deck because it can make it easy to get these alternative engines setup without having to do it manually.
Luxtorpeda can be downloaded directly, but the easiest way to install it is through tools like ProtonUp-Qt that let you manage and install different proton versions.
Here’s a list of supported games
edit: I accidentally linked the list of supported games for the in-development version, which is much shorter than the full list for the stable version. It’s fixed now, sorry for any confusion.
This will be nice, but it’s pretty much a “You only need it when you need it” kindof tool, due to being pretty highly specialized.
Plus I know some engine remakes are still not quite there, like the Theme Hospital One (mostly presentation, gameplay mechanics are all there) and the Warcraft 1 and 2 ones (again mainly presentation, especially when it comes to Audio which is just run in soundtrack mode and includes menu music)
I’d imagine they could add ScummVM as well, but it’d take a lot of time to figure out how to get all the files into the right places probably, since I doubt every ScummVM game does it the same.
I accidentally linked an incomplete list of supported games. The full list is here, and does support scummvm.
