Wait a second, wouldn't the textures be better on the PS3 version? Since every PS3 has a hard drive, and not all 360's do (doesn't this allow Rockstar to cache shits on the PS3 version). So in the end, wouldn't the 360 version get pop-up textures while the PS3 one is much more smooth?
I honestly don't know, but from what I've heard this was the case.
dont forget that PS3 have an 3.2 GHz Cell Broadband Engine with 1 PPE & 7 SPEs
GPU NVIDIA-SCEI "RSX"
Media Blu-ray Disc
DVD
Compact Disc
Super Audio CD (20 GB, 60 GB, 80 GB models)
System storage 2.5" SATA hard drive
(20 GB, 40 GB, 60 GB, or 80 GB included)
