Ouch, thats not good. Is there no plans at all to bring other threads in?, this seems to be a silly thing for the developers to have done, after all they must know their physics engine and damage model is already maxing a single core, you add more racers AI and you talking major slow down, from the cpu bottleneck.
Is there no talk of adding dual/quad support? , nightmare!.
I mean what rig can run this with lods up and 20 A.I cars, with a smooth grid, looking at other games like GTR2 etc they manage it.
I though this game would be eaten by my computer, only to find it does'nt use half of it.
