I managed to play a couple of the training levels last night and I love what I see so far. My only complaint is that the game stutters whenever I move my head around. The framerate is fine if I'm still, but as soon as I move my head it skips all over the place.
Is this an optimization thing affecting the beta for anyone else?
I think theres a whole discussion on the forum about some Nvidia drivers that cause stuttering in VR.
I haven't updated my drivers since then, and just got in to the Beta today, so I'll try a test when i get home later to see if I get any stutter in the Tutorial.
