Is there a possibility your GPU is throttling, due to heat buildup? I have three 1080Tis, all of which typically process a 10496 work unit at about 1M PPD. I have overclocked the GPUs, but only at a minimal 100MHz core boost. They stay relatively cool, typically at about 65 to 70C core temp.
Keep in mind also that a 1080Ti working a 10496 WU pumps a lot of data through PCIe bus. If there are multiple video cards Folding on the same motherboard, it can very easily saturate the bus.
