Hardware Accelerated GPU Scheduling (Win 10)

I noticed that CPUid HWInfo now reports GPU load as 0, while GPUz correctly reports 92-100%.

There's much more than 1 readout for GPUs.
Your average GPU utilization is derived from 3D calculations.
There are 2D calculations (usually not compute intensive), compute data and more.
Here's an example of the sensor metrics of a relatively simple intel GPU:

Code: Select all

                   render busy: 100%: ████████████████████                   render space: 2232/16384

                          task  percent busy
                            CS:  99%: ███████████████████▉    vert fetch: 0 (0/sec)
                           TSG:  98%: ███████████████████▋    prim fetch: 0 (0/sec)
                           VFE:  97%: ███████████████████▌ VS invocations: 0 (0/sec)
                           GAM:  61%: ████████████▎        GS invocations: 0 (0/sec)
                          GAFS:   2%: ▌                         GS prims: 0 (0/sec)
                           TDG:   1%: ▎                    CL invocations: 0 (0/sec)
                                                                CL prims: 0 (0/sec)
                                                           PS invocations: 0 (0/sec)
                                                           PS depth pass: 0 (0/sec)

If HWmonitor took the TDG values, it would show only 1% GPU utilization. While it's easy to see that the GPU is crunching on data.
