One of PS3′s original memory weaknesses was its large Operating
System memory footprint, but it has once again been slashed. The
console originally had an OS footprint of around 120MB’s spread
accross both the XDR and DDR Ram, which was soon reduced to 96MB
(64MB on XDR and 32MB on DDR). Compared to the Xbox 360′s total
32MBs used for its OS, the PS3′s was incredibly bloated. And
lets face it, PS3 developers needed as much as memory as they
could get. However, according to Sony’s latest documents, the
PS3 is now only using 50MBs for its OS, despite the addition of
many new features, such as the in-game XMB. 7MBs of local memory
is used, alongside 43MBs main memory. So how have they been able
to reduce the memoy usage while also adding features? The answer
is actually in that very question. Unlike Microsoft, who knew
what features they were going to use their memory for, Sony was
still in the deveopment stages when they launched the PS3.
Therefore, they reserved a big bunch of memory for future
