I've actually been interested in trying this out as well. What are people's system specs, and how well does it run on your computer? (e.g. any parts of the track where it suddenly gets laggy, any problems with having multiple cars running, etc.) I've read up on the Minimum and Recommended system specifications, but my experience is that I usually have to take those with a grain of salt, since I am pretty much running on a 6 year old machine. (Specs below.)
AMD Athlon XP-M 2500+ (1867 MHz) o/c @ 2520 MHz
Gigabyte GA-7nnXP nForce 2
1 GB Mushkin Black PC3200 DDR
BFG GeForce 6800 OC 128MB AGP
Anyone running a similar setup? Any hiccups while trying to race? Your thoughts are appreciated!
