Here, I made quick video. That's Titan X @ 1440p with 4xAA. I don't really play Sacred 2, I didn't have another spot to test it, but looks like all these leaves are physx-accelerated. Lowest FPS I saw is 56, and I don't think that was due to physx. It was still caching new area as I was running. The whole time GPU usage was around 50%, I don't think Titan would have any problems keeping 60 FPS in this game with physx on.
