An OS memory hog is a thing to fear, especially in a system where memory is fixed, like the PlayStation 3 (PS3). Sony initially gobbled up 120MB of the available memory, spread across both the XDR and DDR ram, which was later reduced to 96MB. But that still looked pretty chunky in comparison to the Xbox’s OS svelte 32MB. Oink, oink.
Sony’s put the PS3 OS on an even stricter diet, and has reduced the memory footprint to 50MB, at the same time Sony has upgraded the OS’s capability. Now game developers have 70MB of memory more to play about with than when the PS3 was first introduced, and the PS3 is a more capable console--a win-win.
Mark Wilson at Gizmodo likes seeing the OS trimmed down, and handing over to developers what’s best left under their control. But, he doesn’t see this as remaking the PS3 into something it already isn’t. Wilson says about the best that will come from this are “slightly nicer lighting effect[s]”. Still, it's a start.
