VRAM Utilisation full or nearly full during idle
Recently I have noticed abnormally high (90%-100%) VRAM utilisation when doing nothing, no apps opened. Even stranger, GPU usage is very low, something u might expect when idling.
When using task manager to try and find the culprit, there was none.
My laptop has a Radeon Pro Vega 20 with only 4gb of VRAM therefore it's a problem.
It happens on Both windows 10 21H2 and MacOS Monterey 12.3.
If anyone has experience on this topic, any advise would be much appreciated. If it's on any help there wasn't any software updates lately on both the windows side and MacOS side.

Gpu core usage is minimal, 1-5%.
The pro Vega 20 is the dedicated gpu and the UHD 630 is the igpu
As of now only rebooting works, after a while it’s back to full vram usage

For Win10 Look at the process manager and see if any processes are using the GPU, you may have to add GPU Engine to the list

Thank you for help, I believe it was the boot camp unified driver 20.45.40.15 that was the culprit, it was released about 3 weeks ago. I since then install boot camp custom drivers 21.50.02.01 and at least on the windows 10 side, it is back to normal. With manual driver updates disabled on macOS I will have to wait for apple.

Np
had a feeling it was going to be driver related leak.
