It seems huge CPU consumption under Windows makes v.10.1 on NVIDIA rigs with low-end processors useless. I have 5x1060 GTX and Athlon X2 240 CPU. Only two cards are able to produce 5 CPD each and 100% CPU load. All five cards produce 10 CPD. Definitely we need fix

Have you tried to edit cpuload setting @config.txt?
He's right. On nvidia cards cpu load is high then on amd.

2500k@4.5Ghz is not enough for 1080ti - one thread is loading 25%... I wanted buy ryzen for this my main pc, after that i'm thinking about new coffee lake.
