This is a well know issue, can you fix it pls? For me the last stable version to read gpu usage is driver 18.9.1, but i need the most recent driver cause some games, like Overwatch will crash otherwise. I'm using iGpu Vega11. Directx cannot read gpu usage, AMD Radeon Overlay neither MSIAfterburner or HWinfo64 works showing all 0% usage. This is very annoying cause is the most importante value to check!
Hope you will fix it asap.
