I've never used proton, that was just heresay feom my gamer friends using steam decks. I remember having problems with wine in the late 90s but the single data point of that xml app was really good. I guess I just got lucky. Running a windows vm in linux has never worked as well as the ither way around, but it does work. And for people with critical software that runs on w95 or some version of dos it isn't unusual to keep it in a vm with extremely limited connectivity. Do you think that might be a reasonable approach for the gp?
