Low/Unstable fps with good specs?

I’ll use Duskwood as a reference, as its an older zone and thus expected to run better, though similar experience in new zones.

My fps wildy springs between 90-350fps all the time, i dont have anything i would call a stable fps, but that would likely be around 110fps.

It’s a fresh install, fresh PC, all drivers updated an running.

Specs:
r7 9800x3d
rtx 5080
32gb ram

Naturally my settings are maxed out, but it doesnt change much if i go up and down settings wise, and i’m usin 1440p.

I’d hope for a more stable and smooth experience with such specs, so perhaps something is wrong?
