Desktop Window Manager, high GPU usage
eloise -
Hello,
I've had my PC for a few months now and I've noticed something: My GPU is constantly at 20% usage (with the desktop window manager) as soon as I open my browser with a video playing in the background on my second screen, which should normally be handled by my integrated graphics processor.
The latter only runs at 5% while the GPU is at 20%. When I switch the browser to my main screen, the usage of the integrated graphics processor immediately drops to 0% while the GPU stabilizes around 25%. The GPU runs at 6% when all windows are closed except for the task manager.
This isn't a HUGE problem, but having a PC that functions as expected is still preferable. How can I offload my GPU to my CPU for all uses on the second screen?
I have all drivers up to date (checked with Avast Driver Updater, and the software from various manufacturers, NVidia, Intel, Gigabytes, Corsair...) and my issue was present even before I made several updates on my components.
(Desktop PC)
GPU: Asus TUF Geforce RTX 4090 OC Edition
CPU: Intel I9-13900K
Motherboard: Gigabyte Z790 Aorus Master
Thank you for your responses.

Hello
The PC and the programs
Everything that can be processed more quickly by an external GPU, RAM, or SSD without going through the slower CPU, which keeps the main activity available for the user on the active window, is optimized and seems to work well.
Staying in control is important, but if everything is organized for performance, especially in programs with automatic management that escapes the user, working silently in the background.
It seems to me that the GPU CPU is already more accessible for you because everything that can be managed is handled in the efficient GPU circuit. I suppose it would need to be brought back into CPU processing in the foreground to start with???. I'm not sure.
There's also energy saving that could switch to the GPU process only during low global activity to use the external GPU more and reduce consumption, but again, this is dynamic based on low global activity, not for a single function or a single screen permanently, I believe.
If the GPU is working hard, it's because you're asking it to do a lot of things at the same time, which it can handle at high quality, high resolution, with many active features, numerous windows and programs running simultaneously, most of which are in the background. The only remaining issues are any parasitic programs that need to be dealt with by anti-malware to lighten the external GPU.
Or a bug if it’s the "Desktop Window Manager process that consumes external GPU" directly as the title might suggest, but there I don’t understand, it exists to consume RAM yes.
