While it's a crying shame that Sony's PlayStation Move won't have full four-player support, at least the technology is efficient; our buddies at Joystiq are reporting that the camera-and-wand based motion control game system will only minimally impact game performance. Quizzing Sony's David Coombes, they found out that the advanced image processing required to make sense of your wild, flailing movements will take only 1-2 MB of RAM. Of course, when you consider that the PS3 has only 256MB of fast XDR memory to begin with, that 2MB isn't as "insignificant" as Sony would have you believe, but coupled with the company's claim that the whole shebang takes "under a frame" of the Cell CPU's processing time, we're inclined to think it won't be much of an issue for the end user. Assuming they fix that nasty lag, of course. Check out our full PlayStation Move guide for more details.
