Hello, first of all, my computer specs: Pentium IV 3,6 Ghz 1 GB RAM Asus X800XT I have a resolution set at 1600x1200. When I play the game (I'm at the beginning of the Peragus level), something strange happens: The FPS and performance is good. But: when I walk (run) with my character, he gets slower and slower with every minute I walk, until my walking looks like slow-motion. Please note that the FPS (frames per second) is still great, only my characters movement animation is too slow. I hope you understand what I mean. Please help. I tried everything like changing the resolution etc. Thanks, Frank
