I have the newest version of physX, and I also can see the same message.
I have different problems with the game:
- The neverending loading screen (just before leaving the first Village) Sometimes I can resolv this when pushing ESC in the dialogue.
- The optimization is too bad. Fps in forest is very low (20-38). Inside the building it works better. (50-60 fps)
Need a Patch now!!!!!!
