Interesting read. Basically it's not the game playing they say requires 64-bit, but the game authoring. That I can certainly believe. On the other hand it mentions reports of 30% speed-ups on 64-bit platforms from the Counter Strike developers. But apparently that has nothing to do with having a 64-bit address space, but rather because the x86-64 architecture has more registers and because the 64-bit CPUs at the time of writing (c. 2002) had some other performance features that were missing from the x86-32 CPUs of the time. I'm guessing all but the difference in # of regs has leveled out by now. Wonder what % boost that gives these days. --bb
