Locked on PS3 and 360 pretty much at 30 all the time on the original. The demo on XBL of the new game is most definitely not hitting 30 very often.
Okay; I knew something felt off.
I know that the demo for the first game had a lot of framerate issues (that were mostly sorted out in the final version of the game).
Here's to hoping that the final game will be an improvement.
