3.44 is out with higher priority for the CPU side of the GPU tasks and the scheduler was updated to use 0.01 CPUs. Both are to try to sort out some of the low GPU utilization or stuck/hung/idle GPUs. If these don't do the trick then there is at least one other change we will try reversing.

All feedback is helpful! Whether good or bad esp on: desktop latency, cpu usage, gpu utilization, etc.
