Really really good fps even with my barely decent laptop. I personally love the fact that there are no barriers because I think that helps with the smoother fps and leaves less things to crash weld into.
I find it fun to try to run different styles of vehicles and try to beat my best time driving up and down with each car. One for example a roamer tuned to drive like an overpowered stadium supertruck (three wheeling and all,) vs a 4wd Race Pesima with rally suspension and James 2102's 4-AGE ^_^
Map is a basic one road hill climb with a lot of switch backs and varying grade changes, some of which are very steep. Might cause problems for some vehicles trying to climb those grades. Also, some of the changes between those grades can be a bit rough, cause your car to jump and so on, but I don't think that's a bad thing if that's what you're looking for.
