How is this game for beginners but also the "most track-hardened racers" with 30fps? If you are really a race junkie who cares about every millisecond you have to have 60fps and not the best looking trees.
Nothing wrong if they care more about that but I don't think that this sounds like a perfect idea for these track-hardened racers. Most other people won't care about it and will be fine with better graphics instead.
