This usually shows a sign of a CPU bottleneck.
But cpu usage is not at 100% most of the times only when driving really fast.
This is why you don't go by % of usage but by benchmarks. Have you checked the FPS you are getting in the game? Is it about the same as benchmarks for the 1060 card? Just looking at % of CPU or video card will not give you much unless you actually have issues and not just looking at the usage numbers. If your FPS is say 20 for a good system, then you look at where the issue is. If you are at 50 FPS on max settings, then % use does not matter, the system is running as it should.
