I have read a lot about the difficulty in obtaining decent fps and performance for the obviously good graphics the game can offer. However, I have the following spec and run full details @ 1240 x 1024 with only heat haze and video walls off.
Processor occupancy is less than 100 on grid and never above 150.
K7s5a mobo
512 DDR
Athlon 1800 XP
Creative Ge Force 3 ti 500
Belinea 15" monitor
Hard disk fully defragged
Cachemen freeing up over 400 mb memory for game
Game is a treat to watch, if only I could get the installation of updated cars right! (see post below for help please!)
