Well, I have been saying it for a long time, but now it looks like I am in good company. In an interview with Boot Daily for a piece on Intel’s Core 2 QX6850 chip, John Carmack said, “I am not a believer in dedicated PPUs. Multiple CPU cores will be much more useful in general, but when GPUs finally get reasonably fine grained context switching and scheduling, some tasks will work well there.” Well said John, there is really no reason that GPUs and multi-core CPUs won’t be able to do all the work needed for physics in future games.
