PlayStation University discovered back in December that optimizations in the PS3 OS has led to a reduction of its memory footprint – down from 120MB to 96MB to now just 50MB. Even with this massive reduction though Xbox 360 is beating Sony in memory footprints with the 360 OS only using 32MB.
Now SCEA’s Patrick Seybold has reported to Joystiq.com that this memory can now be used by developers for their games. This means there is 70MB more RAM to work with than there was at launch. This combined with the optimization developers have leaned over the past couple years will mean that games may now look better and run faster.
