Diablo IV beta unplayable

I was in the early access weekend and it was OK, but choppy. But now I can’t take a step without the screen freezing or otherwise moving like I was in stop motion animation. I lowered all of the visual settings but it still freezes or moves jerkily.

I have an Intel Core 2.6 with 16G and a GeForce GTX 960M on Windows 10. Certainly not top of the line stuff, but I can play WoW on max setting without issue, so it seemed odd to me that I can’t even get the basics to operate on D4. I guess it could just be beta issues, but it seems like many other people are playing without a problem, if the length of queues is any indication.
