I get micro stutters maybe once per race... but nothing that lasts longer than maybe... geez... 0.2 seconds? My hypothesis is that it happens when something catastrophic happens somewhere on the track and your client has to all of a sudden do a physic simulation of what all the cars involved should look like when they smash into each other or into barriers or whatever. Just a guess, though.

I've also read that that kind of freezing can be caused by various in game apps that are probably not handling something optimally. Of course, narrowing that down is going to be a tall order given the infrequency of the issue. :|
