Game is literally unplayable after today’s patch. Freezes within seconds or minutes of start. I assume this is the trick portion of trick or treat.
Edit:
Game is now playable again after newest patch, even with couch co-op. There is still some stuttering in Kurast, which I assume is related to texture optimizations or something.
Edit: So, only mostly playable. Game will freeze on map transitions ~10% of the time and still randomly elsewhere, though much less frequently than before.
