I'd like to be able to play with 47 to 59 AI opponents. I've found out the hardway rFactor & Assetto Corsa are very reliant on single core performance. Even with 28 opponents in rFactor, there's an unbearable amount of stuttering with AI vehicles. Reducing visible cars to 20, doesn't seem to help on Nordschleife. Cpu occupancy was at 90 to 100% I'm hoping to get a used processor and mobo in the $150 to $200 bracket, and overclock it, since a ryzen with new mobo and ddr4 ram will cost over $450 This video seems promising, as 24 car grid in AC on my Phenom II, displays CPU occupancy errors at top of monitor's screen, but still a bit more playable than rFactor 2.
