Congratulations indeed!
Graphics : very very good feeling of immesion! Lighting, reflections, objects textures, effects,detailed cockpit, all very nice, it's visible lots of effort has been put in here. Only this is well worth the 20$. Track IR working flawlessly.
AI: also good, they seem to react well, traffic is ok, still I believe momentum should be stronger, the movements of traffic participants should be smoother.
Physics: good enough for the game's purpose. It would be nice to have more realustic tyre behavior, especially in the wet, but this may be a difficult thing to do.
Map: Nice, for a while, but I really hope you will keep adding new pieces to it.
Wheel implementation and feedback: here I have some problems. Although there is friction, there is no spring to center when in movement, the wheel feeling too flimsy and giving a feel of lack of control that one has in real life. Is there some setup I missed? I dont want to do it from the wheel profiler because it is stupid to have it all the time. It shoud appear only in movement.
System requirements: well I have a decent video card (GT9600) card and a E8500 dual core at 3.4 ghz and even on medium settings I would feel better with a higher framerate. (btw, can we have it displayed?)
Thanks again,
