The tutorial posted by the devs dont say anything about runners in lutris which is very important for gaming. GloriousEggroll releases modified proton to run in lutris.
Posted that in post 2 from my topic. The devs should write that as well in their tutorial and not talk about adding steam in lutris. Why would you use lutris for steam anyway ??? Does not make much sense to me.
You can see their latest version -> Wine-GE-Proton7-35
