Problems and Help :
GTX 1660 Ti GPU utilization only 1%? Can more be utilized?

So, I upgraded to a GTX 1660 Ti a year ago, and have been doing number crunching with it in PrimeGrid, etc.
But I was curious:
When I look in the Task Manager, it says GPU utilization is only at like 1%, despite the fact I've got GPU WU(s) running.
Is this normal? Is this wrong? I would think that it would be throwing the full might of the GPU at number crunching if GPU WU(s) were in the pipeline & being actively worked on?
Is it reading out wrong? Am I thinking about things wrong?
Does a GPU WU really only utilize 1% of this card's number crunching potential? Or are GPU WU's only able to use some specific portion of the overall GPU's ... architecture, processes, whatever?
If a given WU is only utilizing 1% of the GPU, can one run additional GPU WU's to max it out to like 75% or 95% utilization, etc.? If there's extra compute capacity that's simply going unutilized but which could theoretically be used?
Or is it somehow partially CPU-bound, too? Where like if the CPU had more cores (threadripper, etc.) or was at a higher clock speed, then the GPU could be more effectively / completely utilized? Like how much of the compute is GPU-bound vs. CPU bound for the GPU-based tasks? I feel like ideally I'd want to utilize all of the GPU's compute capability, if only a fraction is currently being used. (Or, would I have to completely revamp / rebuild the system for that to happen, if there's some CPU-bound component to the GPU computing, too?)
Sorry if it's a dumb n00b question... ;) Just trying to understand... Like is there some simple setting to make it use all/most of the GPU's processing power, or is there some other factor going on there?

Windows has no way to reliably measure GPU utilization. Just ignore what it's telling you. Your GPU is working fine. Windows is geared towards using a graphics card as, well, a graphics card. It's not expecting the graphics card to be doing caclulations.
If you want to actually see real metrics for the GPU, run an actual GPU utility such as EGA Precision, MSI Afterburner, or GPU-Z.

As mike said, GPU-z is a good way to monitor gpu utilization.
Also, you can change the task manager gpu monitoring to cuda. It should show any primegrid gpu task there. | |

I use MSI-Afterburner for both my Nvidia and AMD/ATI gpu's and it shows all kinds of stuff including gpu load. You can even change the fan speeds with it.
Here is one place to get it

Ohh, okay, thanks...
Yeah switched it over to CUDA and that graph shows 99% utilization but the main graph on the side panel still only says 1%. Silliness.
Already had GPU-Z installed, so I pulled that up, and it says like 93% load or something like that.
So, I guess all is good.
Thx for the info. Won't worry about it, then. Sounds like Task Manager is just mildly dumb and everything is otherwise working fine. Guess you really can learn something new every day... ;)
