One of to things I can think of that might be of help. Ok u have an integrated S3 ProSavage with 32 megs ram, do u know if u board as an brown colored slot on it or an empty white slot. It should be close to the cpu but not knowing the layout of an HP mainboard I not to sure. If u do I would get a little bit newer agp or pci video card in and see whats hapepens. If u can't do those reinstall XP without the SP and see if ur framerate goes up
