Me either. Just a guess. But I have read that in the past. The snow/rain/fog/embers is the only thing the 6th processor uses.
No, they use all 6 SPUs for various stuff (anti-aliasing, physics, lighting, particle effects etc.)
Check this out:
The only problems I'm having on Fort is the framerate.
It seems to be much much less then in any other map, maybe it's just me or maybe it's because of the rain but I can certainly notice it.
Oh yeah, this reminds about a funny glitch that happened few weeks ago. I was playing Co-op in Fort with randoms and I noticed that Drake had some "issues" with his left hand.
Everytime I started moving, his hand just suddenly became very rag doll-ish (you know, wobbling, shaking, stuff like that), and if I stood still, his left hand went inside him and he looked like he was missing the whole arm! Hilarious!
I wish I owned a recording device.
We REALLY need cinema for Co-op.
