I came across it on BHM looking for new games to play obviously. I couldn't play it on my first emachines because of the physics being too much or my on-board couldn't handle, or both.
I ended up building a hodgepodge of a p4 1.7, 6200 and 1gb of assorted ram and running that allowed me to finally race and drive without problems.
I probably liked it because it felt similar to Viper Racing, but better graphics and way easier mulitplayer.
