hey I am running 800x600 resolution, getting average of 23fps. 
I have all visual specs on min,  
30 view distance 
30 detail distance 
14 car density 
0 shadow density. 
I am using a pc with 
2.6ghx dual core amp cpu 
512mb nvidia 8500GT 
5.5gb ddr2 ram. 
Windows vista ultimate 64bit 
What can I do to get more fps (preferably 30+) 
I have gone to nvidia control panel and made the max pre-rendered frames 8.
