For me, performances is good. It defaulted to "High" settings so I left it there.
3700x, 2070 Super, and at 1440p I'm averaging fps in the 70s and 80s. No complaints about performance.
The bugs, though, are numerous. Too many to list. No one bug by itself is that bad, but all together it's pretty shoddy. The rain freezing in place was especially stupid. A couple times, my LB ability (to heal myself, I think?), despite it being ready, just wouldn't trigger no matter how much I jammed on the LB button. A lot of UI items in the menus just aren't showing up.
No crashes yet, though.
