Stuttering - workaround to avoid

In short: after the game has loaded the "track scene", go into the options menu:
Graphics (standard) / V-Sync
and switch it off and immediately on again.
That's it: start or continue the race and enjoy how smooth it runs now.
Disadvantage: you have to do this each time a "track scene" has been loaded.
@Codemasters:
Do you think you could implement switching V-Sync off and on each time a "track scene" has been loaded in a new patch?

Would be much appreciated!!!

Long version: The patch notes of version 1.5.1. said they solved the stuttering in case V-Sync is switched on. But in my case the stuttering did not disappear. So I wanted to see if it would disappear if I switch V-Sync off. No, it did not disappear. But after I switched V-Sync on again (during a race!) the stuttering was gone!
It is a completly different feeling to see how smooth it runs now! OK, the trick has to be done each time, a "track scene" has been loaded, but it takes just a few seconds and it is really worth it.
