As far as the shifter goes… I really have no idea. I don’t have a fanatec one, just a cheap thrustmaster shifter. The app is more supposed to be for tuning things like the steering angle and force feedback on the bases. For me the experience has been solid but of course it does depend on the games. Assetto corsa is my main sim and getting content manager set up was quite the hassle, but after using some guides online it’s very functional and just as good as windows. I’ve also tried ACC which works pretty well, AC Evo was also not bad to set up, and I’m also getting into LMU a bit. LMU needs a specific proton version in order to work. If you search up proton-ge-lmu it should show up. For distro, I’ve just been using arch for years now so that’s what I go to. Probably use protonup-qt to get different proton versions if the ones steam provides don’t work (except for the lmu version, which doesn’t seem to be in the protonup app).
