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 😅
