The framerate is pretty bad...like across the board. Dark Souls was only bad really in Blight Town. No idea why the performance has taken such a hit.
I noticed this too, it never hits the lows of Dark Souls, but it seems to be constantly struggling in a way Dark Souls never did. That said, I went to Redbox and picked up the 360 version and woah! I'd swear the framerate is almost double what it is on the PS3 at all times. It sucks because I think the souls series works so much better on a Dualshock controller.
Yeah it never gets truly awful like Blight Town did, but it happens way more often. The hub area is a good example of this. Maybe all the lighting and the water and stuff. I'm also on the PS3 and have heard that's the version with the frame problems, whereas 360 has worse tearing or something.
I can deal with it, but it also hurts my eyes for some reason.
So slightly off topic, but for those that have tried the Twitch streaming...is there anyway to adjust the camera properly on your face in the settings, or do I just have to manually move my Kinect around? I figured it would just zoom in on my face automatically, but instead it's cut off. >_>
