Part of the reason it felt like it was chugging for me is that there was some jank in how the mouse controls work combined with the fact that the class I was playing seems to have some animation issues. The running animation doesn’t loop smoothly, there’s a jarring gap at the end where it 'pops" back to the start of the run animation, if that makes sense. The two of those things combined to make it feel like it was chugging along pretty poorly, when it wasn’t actual frames being dropped (just looked like!).
That being said, it still didn’t run great, and this is on a 1080. I’d honestly hold off to see what they have to show in May. Right now I think the game has potential, but if it shipped right now I wouldn’t really recommend it. It feels very light for a $50 game.
