Playstation Move Doesn't Have Much Of An Affect On The PS3's Performance.

Perhaps opening the door for "optional" Playstation Move controls in a range of different content, and certainly suggesting that Playstation Move games can look as good as their DualShock counterparts, Sony has announced that Move takes just 1-2mb of the PS3's memory to run.

The tiny amount of processing was announced as part of Sony's tech presentation of the hardware during GDC. Sony also announced that the hardware takes "less than a frame" to translate motion controls into the gaming experience. In short: you can make really, really good looking Playstation Move games with motion controls as responsive as a standard controller.
