Just wanted to let you guys know in case you didnt. This game is alot of fun. Its more of an "authentic" off road game. More slow paced, and a really cool physics engine. It runs great with a voodoo 5500 card too. Its from around the same era. Another one of "those" games that might not look the best, but is alot of fun and has great gameplay. Heres a link to the demo. Im not sure how the demo runs though, I bought the full version off of egay. The main problem I had was controller issues, but that was fixed with a patch I found on the net.
