Windows 10: Dedicated GPU is not being used by applications or appearing in Task Manager. How do I fix...

Device manager says that the dedicated GPU was stopped by Windows Error 43 so I followed some basic troubleshooting of disabling and enabling it within device manager, deleting and reinstalling drivers through multiple methods, and have even done a full factory reset of my laptop. The issue remains. What other options are there for fixing this issue?

GPU graph is not seen in task manager

Hi Sree,

You can now view GPU performance in the Task Manager in Windows 10 if you have a dedicated GPU, the Task Manager will show you performance stats for both the integrated and dedicated GPU since you just mentioned that you've already upgraded your PC to the Fall
Creators Update. But, since the GPU graph is not showing on your PC's Task Manager, there's a possibility that your computer wasn't meet requirements for GPU in the Task Manager. To know more about it, you may check this article:

Games and applications are not using laptop dedicated GPU

Since I upgraded my laptop to Windows 10 1909, I'm having an issue where applications do not use the dedicated Nvidia GPU , despite having set programs to use the high performance GPU on Nvidia Control Panel. Even if I right click the shortcut or executable and choose to run the game or application with Nvidia high perfomance processor, it will still run on integrated GPU, resulting in less than ideal performance. Actually, in some rare instances the programs will run on Nvidia GPU, but after rebooting the machine, the issue comes back.

I have Nvidia GPU activity icon enabled in the notification area, so I'm able to check whether the dedicated GPU is being used or not, and most of the times it's not. I have already reinstalled Nvidia graphic drivers, but this hasn't fixed the problem.

Info:

OS: Windows 10 Home Single Language build 18363.476 (version 1909)
Nvidia drivers version: 441.41
integrated GPU: Intel HD Graphics 4400
dedicated GPU: GeForce 840M
