I have been loving it, and haven’t noticed any issue. I used the default settings. I heard the third act can be taxing, but I’m not there yet. I think people who complain about the performance haven’t actually played it.

played through it on release, act 1 and act 2 were fine, occasional dips below 30fps.

act 3 had a lot off texture pop in and walls that would only appear after some seconds, but the game received performance patches after i finished it, so probably better now.

I’ve been playing BG3 for about 70h on the steam deck. Performance isn’t perfect, but it’s definitely playable on 30fps and low graphics. I’ve just got to Baldurs Gate city and I noticed the audio stutters slightly in busy areas. That’s the only noticeable performance issue I’ve had.

I have only played it on the steam deck so I have nothing to compare it against however. I’d love to play it on something more powerful so I don’t have to see it in potato-level graphics tho 😅
