Just for a laugh I copied Q3 over to a 330MHz BPPC system with Voodoo 3. It works about half the time (the other half throw WarpOS exceptions) but only runs at about 5 fps tops! Pretty close to getting the beers in between frames, Cowcat!
PS this system has 192Mb in it which is the absolute min. Less than 20 megs free when it's running.
