Not sure what the last guy is on complaining about bumps on a track from 1967. That's kinda how they were. It's perfectly playable and as someone who still plays GPL, it feels just right unlike GPL where you couldn't model bumps. The only issue I have is the AI with the GPL mod, not sure if it's the track or the car mod but the are hopelessly uncompetitive, I'm not that good and lapped the entire field in a 20 lap race I just finished.
