I mean I don't know all that much about doing anything on the PS3. But VRAM is basically used to store textured which are later shown on the scren, the less VRAM the less texturing you can have. Edit: To compare, I'll use WoW. Checking "High Resolution Textures" takes up 1.2 gigs of RAM plus whatever it uses on my 1 gig video card. Going to Low Resolutoin Textures, it drops to 950MB plus whatever got freed from my 1 gig video card. |
Indeed, the video memory is quite a trouble for consoles and fps are among the worst offenders because they allow for exteme close-ups of surfaces, so you need more LOD steps.
I'd like to add, though, that those are actual in-game shots of KZ2, a game that chose other image quality features over crispness: the object-based motion blur does wonders against framerate dips in critical moments, but it doesn't really do screenshots much favour. The same could be seen in GoWIII demo/final comparisons, where the final screenshots sometimes appeared more blurry than the demo ones because of the added motion blur, though if you watched it in motion the improved texture and per-pixel lighting detail was evident.
On the other hand the Crysis 2 shots are extra crispy. They are probably using a dedicated "screenshot" rendering mode with extra detail and special treatment of AA and blur - something that I doubt we'll see in real time if not on meaty PCs, if they want to keep the image quality high when in motion.
