Okay, you probably have lost interest by now, but I managed to find the two options which solve the whole lighting crisis in the game Starship Troopers with new video cards. Terrain shadows must be turned off, and shader quality must be set to low. I am running this on a new radeon 6950 at 1600x1200/32bit@60hz and the fps is unbelievable. Everything else is set to the highest settings.
If you are operating in a language you cannot read, it is the second menu option and the tenth.
