Thanks _Core_, that is all I wanted to know for now laugh

And yes, shadermodel 3.0 is needed for those shadows. But you anyways wouldn´t get an acceptable performence with an graphics card without shadermodel 3.0 support.

Edit: Tai, those are shadows. highquality shadowmapping is just VERY demanding for hardware. In any modern game, you will notice a big fps difference between enabled and disabled shadows. That has nothing to do with gamestudio (at least not that much).
