Windows 10: NVIDIA Optimus for Desktop PCs

Hi

I have an iGPU and dGPU in my desktop PC. I want to have the NVIDIA Optimus Configuration where the iGPU works for normal browsing and surfing tasks, and dGPU kicks in when doing GPU intensive tasks i.e. gaming, video editing, AI programs.

I have plugged my display into the onboard HDMI slot instead of the dGPU's HDMI. In BIOS settings, the Onboard Graphics are set to Enabled.

When windows boots up, Intel command center works fine, but all the settings in NVIDIA Control Panel disappear. It implies that that with single monitor configuration, I can either use iGPU or dGPU for display.

About the usability on the dGPU, I can use it for AI tasks, but for gaming, the iGPU kicks in instead of dGPU, causing laggy gameplay.

The NVIDIA official drivers offer "Display.Optimus" folder which includes some configuration files to enable Optimus configuration in desktop PCs. I want to know how can I do it.

My PC Specs:
MoBo: Gigabyte Z390M
CPU: Intel Core i5 - 9600K
GPU: AORUS RTX 2070 Super 8GB
OS: Windows 10 Pro x64 (Build 1909)

Windows 10 and Nvidia Optimus issue

GTX 750TI is a desktop GPU, this issue only affect nvidia optimus (nvidia mobile series gpu).

 

Why would NVIDIA Optimus activate only for Laptops and disable for PCs

For those who don't know Optimus is some sort of a technology NVIDIA developed in order for laptops to have the ability to switch between multiple GPUs integrated when needed .

They often claim that this approach is to save power and is not needed for PCs really as those do not run on batteries to need to save power (wondering about all people now shifting to led lights home just to save on bills) .

It is controversial however , it is known that there is a performance gain noticed on laptops with such setups as then Intel manage to lift the load of all desktop 2D/3D overlays and memory consumption (Yes the load persist even if in background) leaving the NVIDIA GPU and its memory all dedicated to 3D rendering .

Now what dazzles me is that you get same drivers for laptops and PCs from both Intel and NVIDIA and yet however those drivers manage to somehow detect weather the setup is a laptop or a PC in order to enable or disable Optimus technology .

So I'm just wondering how exactly the driver is able to tell if the setup in hand is a laptop or a PC for one thing , and weather there had been any trick or mean or a 3rd party tool to fool the technology into working on PCs and that's another .

P.S I did not tackle the issue from AMD perspective but i am sure they have similar technology to Optimus and approach to PCs handling .
