Since the day 1 patch, I have been experiencing severe stuttering, while this happens in all racing situations (I have not noticed it during cutscenes or menus but it may not be apparent) it seems unaffected by the graphics settings - I ran benchmarks on both max settings and the medium pre-sets and the large drops in frames were when the stuttering happened and you can see there is no corresponding drop in either gpu or cpu framerate.
I am running high end hardware and have the latest NVIDIA drivers.
