XBox doesn\'t have any VRAM.
Neither does PS2.
XBox can, however, do 8x texture layers in a single pass with no hit on performance, as well as 8x (S3) texture compression.
Are you sure that\'s not the reason XBox can do better textures?
In fact, the PS2 would probably be
worse if it had a lot of VRAM (or in reality, embedded texture cache) as it would likely encourage (lazy) developers to store textures, rather than stream (which is what the PS2 was designed to do).
Then again.. those lazy developers aren\'t exactly taking advantage of the PS2\'s texture streaming capabilities as is, so maybe it would be a good thing
