AMD graphics drivers can eat up 1 CPU core if they don’t detect an installed Radeon GPU

Today we come across a curious news, and that is that the editor-in-chief of TechPowerUp, called with the nickname “W1zzard“found that AMD Radeon graphics drivers they were squeezing a core out of their CPU to the max when the system suffered a GPU replacement from AMD to Nvidia.

As he says, tinkering with an old test PC, he realized that after installing an Nvidia GPU the system became “incredibly slow“for everything from system startup to surfing the Internet. the computer had a 2-core CPU only, this computer had worked perfectly until it replaced the AMD Radeon GPU that it used before with the Nvidia GPU, so the first thing it did was to blame Nvidia, but when it opened the Task Manager it found that the application “RadeonSettings.exe“I was putting a 100% load on one of the two cores when I didn’t have an AMD GPU installed, and that eradicated the notorious performance drain.

If you want the quick summary, this problem affects much less modern CPUs (being much more powerful and having more cores), and it takes place when you keep the AMD graphics drivers when you are already using an Nvidia GPU, something that is not appropriate either, since this event is a clear example of the things that can happen.

“Once that process was closed manually (right click, select” End Task “), performance was restored to expected levels and CPU load returned to normal. This confirms that the AMD driver is the reason for high CPU load. Ideally, before changing graphics cards, uninstall the current graphics card driver, change the hardware, and then install the new driver, in that order. But for a quick test that’s not what most people do, and others just aren’t aware of the fact that there is such a thing as a “graphics card driver”, and what it does. Windows is smart enough not to load any drivers for devices that are not physically present.

It seems that AMD does things differently and just preloads Radeon settings in the background every time the system boots and a user logs in, no matter if AMD graphics hardware is installed or not. It would be trivial to add a “If AMD hardware not found, then exit immediately” check, but ok. Also, do we really need six entries in the Task Scheduler?

I got curious and wondered how is it possible in the first place for a utility software like the Radeon Settings control panel to use 100% of the CPU load constantly, something that could happen when a miner virus is installed, to use your electricity to mine crypto, without you knowing. By the way, this was all verified in the Radeon 20.11.2 WHQL driver, Radeon 20.11.3 Beta and the driver released for an upcoming Radeon review.

I did some quick real-game performance tests on an 8-core / 16-thread CPU and found a little FPS loss, especially in limited CPU scenarios, around 1%, on the order of 150 FPS vs 151 FPS. This confirms that this can also be a problem on modern systems, although only 5% of CPU power is lost (a 16 core). However, the differences will be minimal, and the difference is unlikely to be subjectively noticed. “
