1. You're in task manager, so your system isn't even handling constant game data flow right now.
2. You're using 73% of all system memory available. How much memory does your system have by the way? I'm guessing at least 3GB? Is he supposed to wipe everything short of Windows Explorer before he plays a game?
Great, you've just confirmed my suspicions that you don't have a clue how both Vista and W7 handle memory. I can safely ignore this silly argument now, cheers.
Back on topic, Unreal 2K4 is a good recommendation, still got a sizeable community, craploads of cutom maps, mods and the like, it'll run well on your machine and its only $10 DRM free from gog.com. Get to it.
Trackmania scales pretty well, download the free version off Steam and see if you like it, there's craploads of content but the upgrade to the full version is worth it.
