GPU Utilization spikes to 100% when process exits

My GPU 3D Utilization spikes to 100% when I close processes such as Visual Studio 2019, FurMark, or other WPF applications.

And GPU Cuda Utilization will also spike to 100% if the process which uses cuda api is shut down.
All spikes only last for less than 1 second and only appear when the process exits, not starts.
Can anybody explain the reason of the utilization spike?

Is this spike causing any specific issue that you need to resolve?

The interface refreshed by WPF application will lag at that time

Hi, @KevinZhang94

This is devtools support forum. And we don’t have the knowledge to support your problem.
Please find the proper forum to ask.
Maybe you can initialize at “GPU Hardware” or something related.
