Reduce GPU Folding power

Post by naw »

Hello

I'm using F@H on a system with Ryzen 5 3600, Nvidia GTX 1050 on Arch Linux. When I turn ON GPU folding the desktop, some windows render slowly. I notice in on new windows and also on firefox.

For CPUs you can change the power used by using the power slider or by adjusting the thread number. Is there something equivalent for the GPU? I only have seen that with the power slider you can disable or enable the GPU completely.

Thanks

Sadly GPU drivers do not allow this. It's not a folding thing, just a operating system and manufacturer driver thing.

In Firefox, you can turn off hardware acceleration and the browser will stop using the gpu and rely on the cpu only.

The OS manages a GPU as a single device. It is either on or off. The FAH software, including the slider has to live within the constraints of the OS.

FAH drivers actually manage the device in several ways, but mostly to protect it from being damaged by heat. Within the driver settings, there are some settings that MAY be used to manage the things you're looking for but those settings are not available to FAH's control.

Thanks! Reenabling hardware acceleration and forcing it with layers.acceleration.force-enabled makes firefox smooth again

Search for package "nvidia-smi" and you will land on the NVidia Developer page. This package works on all Linux distros, and allows me to limit RTX 2070 to 150w from allowable 185w without any noticeable loss of F@H PPD, lowers the GPU temp, and makes mouse movement snappier on the screen. Manjaro

If I want to disable GPU and still do CPU work, can I do that through the advance options>slot configuration>gpu-index = 0 ? And when I'm ready to enable it just set it back to -1 ?

Update: Never mind. Found the pause button on the advanced control interface and got it to do what I want from there. :D

You can also use 'finish' in advanced control to complete a unit and not automatically start another while keeping the cpu active and let the gpu finish its work then auto pause.
