quote TTP:

"Just got the *preview* code and spent some time with it in the
comfort of my sofa and I must say the frame rate is all over the
place.

Didn't give me this impression at all at E3, but here, in a more
intimate environment, me and him alone, the times where it stays at
30fps are so few they don't even matter.

Factor 5 either screwed big time or this version is as old as baby
Gesus"

once again, the choice that Sony made to use a lowend Nvidia GPU in
PS3, the RSX, which is based on a DOWNGRADED NV47 / G70 ~ GF 7800 or
G71 ~ GF 7900 with miserable fillrate performance ( 2 Gpixels/s with
4x anti-aliasing) combined with low graphics memory bandwidth (22.4 GB/
sec to GGR3) combined with low triangle setup rate performance (about
250M vs 500M on X360) results in PS3 games with ****ty framerates when
overtaxed by 1080p resolution and too much graphics detail.

it's bad enough that console GPUs are set in stone for the 5-6 year
life of the system, it's worse when a GPU *starts* out being lowend
**** at the *beginning* of the console's lifecycle.
