i agree, since i dont think GPUs are suited to the task.
as for multi cores, I installed vista 64 over the weekend on my quad-core. i noticed the 100% usage of Core 1. After changing the core
affinity for BS in Task Manager for all cores, BS utilised Core 1 and 2, doubling the FPS. I was not able to utilise all cores, most likely because there is only so much one can do with a limited number of threads in the game.
