Windows 10: gpuenergydrv.sys, "GPU Energy Kernel Driver", what does this do? Thanks.

gpuenergydrv.sys, "GPU Energy Kernel Driver", what does this do? Thanks.I see that it is in use, 'started' using Serviwin, Nirsoft software.I don't know exactly what it does, I can't find much on it. I just wondered if I really needed it. Whether it's role is more for laptops where energy consumption on a battery is critical. I might be able to disable this driver and not have it manage my GPU power if it isn't critical, and that maybe Nvidia has its own internal power management in place, I'll have to check.Thanks.

Any way to change in register which GPU is used for Energy saving?

Hi SweetArkhane,

Welcome to Microsoft Community.

Yes, you can change the default GPU used for energy-saving in Windows by following these steps:

1. Open the Windows search bar and type "Graphics Settings" and select the option that appears.
   
2. In the Graphics Settings window, click on the "Browse" button under the "Select an app to set preference" section and locate the program or application you want to set a GPU preference for.
   
3. Once you have selected the app, click on the "Options" button and then select "Power Saving" from the drop-down menu.
   
4. Click on the "Save" button to apply the changes.
   

To change the default GPU for all apps, you can follow these steps:

1. Open the Windows search bar and type "Device Manager" and select the option that appears.
   
2. Expand the "Display adapters" section and right-click on the GPU you want to set as the default and select "Properties".
   
3. In the Properties window, click on the "Driver" tab and then click on the "Disable" button to disable the GPU.
   
4. Click on the "Yes" button when prompted to confirm the action.
   
5. Once the GPU is disabled, repeat the same steps for the other GPU, but instead select "Enable" to enable it.
   

If there is anything not clear, please do not hesitate to let me know.

Any way to change in register which GPU is used for Energy saving?

Hi, I'm not sure you read everything I said^^

Because as you can see, the GPU for energy saving is the same as the GPU for high performance, it should be :

Energy Saving - AMD Radeon Graphics

High Performance - RX 5700

But it's twice RX 5700

----------------------------------------------------------------------------------

The other part of your answer doesn't make any sense...

"and right-click on the GPU you want to set as the default and select "Properties"."
"click on the "Disable" button to disable the GPU."

You want me to disable the GPU I want as default?

"repeat the same steps for the other GPU, but instead select "Enable" to enable it."
The other GPU is already enabled, they're both enabled, but you want me to disable the one I want as default and keep the one I don't want as default enabled...
