Crikey you're determined to prove me wrong but I'm afraid this is not the case.

Textures still need to pass through the system RAM and be stored there, they don't just jump from the hard drive/media to the video RAM. They get decompressed to the video RAM and that's why so much video RAM is needed for a scene for example, one reason anyway.

Anything that is in video RAM has been in system RAM at some point.

Even game worlds that are streamed have to pass through system RAM to be processed.

But at any one time the PS3 can have around 200MB worth of system data and 256MB of video data in memory.


As already explained, that 256MB of video data cannot hold a "game world", it's only for rendering the scene.

I think we've reached full circle here :p

The GPU renders the scene, VRAM stores textures and such, which are part of the game world too. Switch of the PS3's VRAM and your game just got a hell of lot less... well, video. ;)
