Also, on another note, is that not what the RAM is for? I mean as

nothing else is needing that RAM, isn't that ok?
Here are the Crysis minimum requirements: Note that Vista requires a
CPU that is almost 15% faster and 50% more RAM. I guess that puts
the "Vista is just as fast as XP" theory to rest.
No, it really doesn't address it at all. Vista (assuming the card is DX10)
will be running the game under the DX10 codepath, while XP will be running
the DX9 codepath. It could very well be the case that the DX10 codepath is
doing more or different things that simply require more host resources.
While the Crysis requirements could have been segmented in Vista for DX10
and DX9 if that is in fact the case, it's generally best not to complicate
them more than absolutely necessary.
