Here's DFC at 35fps:
The scale is different because I liked to see the detail a bit better. What I can say is that it was better, but still stutters very bad.
There is something wrong here, that's for sure. The stuttering is worse on the first run and even then it gets better near the end. The second run is better from the start, but still not even remotely smooth. It's not universal though, Heaven and Crysis 2 are as smooth as they can.
