considerably slower. The reason I play WC as opposed to Indycar is
because WC is so much smoother. Yes, I do have a 486/66 w 8 megs.
More important then the realism factor is the fun factor. A game has to
be fun. To much graphics overhead will just complicate things.
Put more effort into the features of the game, and don't worry about
changing the graphics to much.
Just my 2 cents.
