"All that RAM" means as much as you quoted, you twit. Since Vista Windows has loaded up your RAM with shit while you're on the desktop, but as soon as you launch memory-hogging software it ditches all that shit and runs on a much lower memory footprint. This is pretty standard knowledge.
Yeah, Windows is just gonna 'disappear' once you launch a game.
Please shoot yourself in the mouth.
