Does the CPU normally affect gameplay?

I've just upgraded from an e7200 to an i5-750 and i quickly noticed that the formerly perfect drivers suddenly forgetting how to drive. On the e7200, they would always obey the traffic rules (using blinkers to change lanes, stay on the right side of the road, avoid collisions, etc.). I do occasionally see swerving vehicles or other glitches, but they are extremely rare.
When i changed to an i5-750, the AI suddenly became erratic.
I have a video made from before i upgraded and watching it again reinforced that something in the AI broke. Cars are now swerving, stalling for no reason, spawning into incoming traffic, driving off the road, etc. I even ran into an invisible police car *twice* in one hitchhike mission. I now stay a good distance behind any traffic, coz when the car in front of me stalls (which now happens often) and i swerve to avoid it, there's also a good chance that the car in the other lane will also stall.
Thinking about what happened here, when you consider that enemy AI's can now go through their decision loops a lot more often, will it change the way they react to you?
EDIT: Forgot to specify the game. It's Test Drive Unlimited.

Only thing that I can think of is if the AI is frame based instead of time based.

Looks like you're right.
I just tried recording a race to make some comparison videos. Fraps pretty much kept the frame rate below 60fps, and the glitches disappeared! Just to make sure, i re-tried the race without recording (fraps says i'm holding well above 100fps throughout the race) and the glitches came back!

What game is that? Or did I miss out something?
