I don't need help, but in case anyone would find this info slightly useful:
After reading the suggestion to lower the FPS to 30, I had no luck using my Nvidia Control Panel to do that; it made no effect.
I notice that in the game installation folder, there's a subfolder called NVI which contains "shadows.nip", probably the Nvidia profile mentioned above. I don't know how to edit this but I wonder if this was overriding the Nvidia Control Panel. The NVI folder also has an "Inspector" program that automatically closes a few seconds after opening, at least on my pC.
Some gamers might like to try to figure out how to tinker with these, if the Gall Spaceport level, its flawed physics, and the loopy controls are causing too much trouble. Or...just use the "R Testers ROCK" cheats to skip the level or blast your way through! :P
UPDATE: I wasn't able to try them, but Pg. 5 of this thread has some advanced methods that might fix things for you.
