I played about two hours of this yesterday and streamed it.

It's awesome of course. Still, framerates are terrible like RO2. I'm running a 670, and I'm trying to figure out why my FPS only sits at 30-50.
Weird, 2-3 months of patching RO2 I got a solid 60 with everything maxed on my 6950 and I'm having no trouble getting 60 with my 680 now. Turn down post processing to low, that supposedly helps.
I tried adding 4xMSAA and 2xSGSSAA with the Nvidia inspector settings on the last page. But I seem to get some crazy graphic glitches with it. Character models stretching over the entire screen and stuff.
