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?
Yes, but effect was minimal. Each Nvidia card takes 100% of one cpu core.
