I have found if I minimize the game (alt-tab) and then restore it back (alt-tab) the sudden drop in framerate goes away as well after talking to Petru. So definitely a bit buggy.

I have the demo maxed out at my native res of 1920x1080 with no AA enabled and it has silky smooth framerates on my dual-GPU EVGA GTX 295 FTW, but it is when I enter Lower Raven's Rill and start talking to the NPCs I run into trouble. If I talk to the trader in the middle of town named Petru and then exit the conversation my dual-GPU's usage jumps from about 50% to 72% for no reason and the framerate is very jerky. If I exit to the options screen and change a video setting like shadows from high to low and apply and then change it back again to high and apply then go back to the game the framerate goes back to normal (silky smooth) and my GPUs go back to about 58-62%. Definitely buggy for me. Using latest NVidia driver 275.33 Vista 32. If I just play the demo the game runs perfect. It is only after coming out of a conversation with an NPC I seem to have trouble and need to do what I described above. Petru being the most repeatable problem.
