Is it a CPU issue?

post #1 of 20
Thread Starter 
hello guys, i installed colin mcrae dirt yesterday and i notices something, when there is AI cars with me even 1 or six cars the game begins to drip frame rate to about 10fps, without AI players it run very smoothly, my hardware is pentium D (dual core)@3.4mhz 2mb L2 cachex2 800fsb, 2 gega ram, bfg8800gts 320mb, i'm running the game on ultra settings (except shadows on high) and it runs smoothly without the AI, but why this huge fps drop when the AI are in the race even if i put the lowest settings with 640x480 resolution its still have the same problem, could it be a CPU problem? should i overclock it ? somebody help please, and btw i have the latest drivers and i tried the game both on vista and xp still the same performance problem...

well, ai does take a lot of processing power so i'd say the weakest link in your system would be the pentium d at 3.4 Ghz

if you have stock cooling I wouldn't advise that but you can look at the overclocking guide here

looking at the system requirements for the game, im doubtful it is a cpu issue you are haveing. i have a PentD 3.2ghz, and im positive i could run it on my system with no problem. it sounds like either a driver issue, or there is a process running in the background that is taking up resources. whenever i game,i shut down every non essential process i can. you can do this manually, or use a program like fsautostart. i use fsautostart, it is free and very user friendly. normally i have about 40 processe running, when i game, it is cut down to about 20. i would try this before i spent any unnecesary cash.
