Video AI -use only 9% of gpu

Hi, is it normal that Video AI use only9% of gpu power? i have AMD7950x3d cpu and 4090 and denoising 20 sec video with ading hdr get 25 minutes. why it uses so few of my mighty GPU?

Does the 9% figure come from task manager?

yes. but it seem that its false couse gpu temperature go up to max so it seem that card is used max

The default Task Manager view doesn’t normally show the utilization. You have to use the dropdown above a graph to select another view, and it isn’t obvious which one should be selected.
