Pcars seems to use more the CPU than the GPU in my i5 4590 and GTX970. CPU occupancy stays on 80% average, while GPU uses around 50%. Racing in Le Mans, 55 cars, Thunderstorm at night. No Vsync. In replays GPU use rises to 80% average. The CPU is bottlenecking the GPU or is bad optimization of the game? (driver problems maybe?) P.S.: Have this issue with AC if i lock framerate, but otherwise GPU hits full use.
