I am seeing tasks (GPU), that when started are using very little of the gpu.
Usually the GPU utilization is about 98%.
With these tasks they are at or near 0% and they take a lot longer to finish.
Something is not right.
Could someone please look at this?
I have not made any changes, and it was running very nicely for weeks on end.

most likely fragmented wu causing your problem.saw a post today about they are rerunning a bunch of the fragmented stuff.just grin and bear it.was a little worried myself,cause mine started acting up today as well.just let'em run,and sooner or later we will get back to the good stuff.
