PSA: AMD's Graphics Driver Will Eat One CPU Core When No Radeon Installed

Theoretically, it should be possible to have graphics drivers from multiple vendors installed on the same machine, because you can have graphics cards from different vendors installed on your system. In this case, it is just a bug in AMD driver

Absolutely. Very poor implementation quality.

I uninstall graphics drivers if I’m switching from one vendor to another (Intel,AMD,Nvidia), under Windows. I believe there is a third party program that can do a complete uninstall of them.

It's called Display Driver Uninstaller. https://www.wagnardsoft.com/display-driver-uninstaller-ddu-

Is busy-waiting with a delay really the right solution here? Wouldn't it be simpler to just register for the event and sleep until it's delivered?

A bug in the AMD drivers? That couldn’t be.
