Question My GeForce experience overlay always says 0% GPU usage

[0Ware]

No matter what game or program I use it always shows 0% GPU usage. This just randomly happened one day and I can't get it to show my GPU usage anymore.

What does the GPU-Z app say about the GPU usage, and other parameters ?

The Nvidia GFE overlay can sometimes be buggy as well. Sometimes pressing the "ALT+R" combo key might refresh the GPU stats displayed on the overlay screen.

Which GPU is it btw ? Kindly provide full PC specs. Also, try doing a CLEAN reinstall of the GPU drivers if need be.
