Set your refresh to 60hz and make sure vsync is on. If not the game goes wacky and the physics are very off. Also the clock utility in the "downloads" section can be helpful. But try the wrapper first w/vsync on @60hz and see if it makes a difference.
Seems neither glide wrapper is working for me. I'll keep on it. Voodoo just doesn't seem to do anything and the first one we tried, artifacts the graphics and the AI still bugs out. Virtual Machine, here I come.
