Yes Vista uses a lot of ram, and yes I understand it's meant to.
drewjustforyou, if the game is lagging that badly, it's probably not your ram. Having 2 gigs free is plenty. You probably want to try resolving the driver update issue first. You might have dl'd the wrong version of the driver, e.g. not the vista 32bit. OR it could have been a corrupted download. In any case, try downloading that again. Make sure that...
1. you download it from nvidia's site
2. that you get the correct driver. (there's a bunch of lists there, just choose the right ones. e.g. the graphics card you have, the os you have.)
"As a result of all this hardship, dirt, thirst, and wombats, you would expect Australians to be a sour lot. Instead, they are genial, jolly, cheerful, and always willing to share a kind word with a stranger, unless they are an American." -- Douglas Adams
