The frame stutter issue that progresses throughout a session until it renders the game unplayable can apparently only be fixed by downgrading steam to a version from 2024?? crazy that that sort of thing can just happen and there’s no recourse. Although maybe if I play it on a powerful enough machine I can just brute force past it?
Oh I played through about 80% of the game on my steam deck but never encountered this issue as far as I could tell.
Unless you’re talking about the issue with the steam frame limiter. If you have it on at all (even at 60fps) the game runs like absolute trash, but I never had much issue running the game without it, even at a limited TDP.
If that’s not it maybe playing around with the proton versions could help? I never had to do it but unless I just have a weirdly golden install of the game you might just want to reinstall the game (back up save files!) and see if that helps at all.
Going offline has actually worked in my limited testing, which is curious
