So I have a pretty beefy system (Ryzen 5800x3D, 6900XT…) and just to let you know Guild Wars 2 tends to run bad even on those systems in certain situations. Most of the time those are situations where a lot of players come together, WvW, Meta Events or Lions Arch in general.
What really helps is setting the Character Model Quality and Character Model Limit to low (not the lowest!) and as a killer feature also put Shadows on Low.
I don’t have the feeling that I loose a lot of visual fidelity and on the other hand I gain a huge performance boost so that even heavy meta events run well above 60fps and feel a lot smoother. Maybe this helps you a little bit.
