FPS issues with mid end pc

I have an RTX 4060 and i5-10400f and 16gb DDR4 with my graphics settings on an already low-poly game set to basically the absolute minimum while still running native 1920x1080. In the hub I get 30-40 fps at most, 7-10 with any kind of GUI open. Dungeons is 20-30 while clearing rooms. Anyone know how to get better FPS on this game, because it’s borderline unplayable right now
