I think this is more about the allocation of virtual memory rather than the way your RAM is being addressed, and it's probably aimed at allowing more of that virtual memory to be available for the game when you're running a 64 bit system. Or something like that. Someone will be along who knows about these things, or hopefully will be ;-) FWIW I can't say I've noticed anything, but that could very well be because I don't know what to look out for...
