Koln To Koblenz Route - Need Help With Stuttering

I've been running some career scenarios on Koln To Koblenz.
There's consistent stuttering, even when there's no AI in the area. I presume this is from the overhead wires.
If anybody has suggestions for optimal video settings when running this route, would be appreciated.
Computer Specs:
Core I3 Sandy Bridge
8 GB Ram
WD Velociraptor
EVGA GTX 750ti
Thanks,
Rob
