For those who don’t know, Proton is the tool that the deck uses to run windows games on Linux. GE-proton is an alternative build of proton that includes extra fixes for games, media codecs to fix video playback, and more. You can easily install GE-Proton by going to the discover store in desktop mode, installing ProtonUp-qt, and then selecting GE-proton from there.

The way that GE-proton is improving mod support here is by recognizing common mod launcher .exe files such as skse_loader.exe. If it sees a mod launcher executable in the game folder it will use that instead of the original game launcher.
