Windows 10: 2.2GB hardware reserved memory after reinstalling the Nvidia GPU driver iGPU + dGPU not...

sdfsdfsdfsdfsdf2.2GB hardware reserved memory.I have a ROG Strix G15RM R7-6800H + onboard Radeon 680M / RTX 3060 Laptop GPU / 16GB DDR5 4800, and at first, after setting it up for the first time, the same 2.2GB was reserved. But after tinkering with it for a while, it reduced to around ~100MB reserved I REALLY don't know how, maybe reinstalling Windows helped.Fast forward to the present: I use DDU to completely remove Nvidia drivers and uninstall Armoury crate and GeForce Experience, replacing them with G-Helper and Nvcleanstall to de-bloat my laptop. G-Helper was fine, the Nvidia dri

Multi-Monitor and iGPU and dGPU usage/load

Hello, I have trouble getting my iGPU to do work when the dGPU is set as "main display".

I have an iGPU Intel HD4000 on my 3770k CPU, I also have a dGPU Nvidia GTX690 in a Multi-Monitor setup. Connected to my GTX690 are 3 monitors, and connected to my HD4000 is a 4th accessory display.

What happens is that when I play a video using VLC on the monitor connected to the iGPU, all content is actually rendered on the dGPU, then sent over the PCIe bus to the iGPU and displayed from there. I don't want my dGPU adapter to have anything to do with
VLC when the window is not on those monitors. I want only my iGPU adapter to do work when VLC is on that respective monitor. If I move the VLC window over to a different monitor which is powered by another display adapter, I want that adapter to take over
the work.

Example - Playing a video on the Monitor connected to iGPU:

1. When iGPU is set as Main Display then; iGPU 17% usage, dGPU1 0%, dGPU2 0%.

2. When dGPU is set as Main Display then; iGPU 18% usage,
dGPU1 8%, dGPU2 0%.

In the first case where the monitor connceted to the iGPU is set as main display, everything works as I want it, only the iGPU does work as it outputs the video to its monitor. But I don't want to have my iGPU as Main Display, I want the dGPU as Main.

In the second case where a monitor connceted to the GTX690 is set as the main display, dGPU1 is at 8% even though no monitor connceted to this Dispay adapter is displaying anything.... For some reason Windows10 lets the dGPU do all the work and pass the
result to the iGPU which then displays it. I want the iGPU to do all the work.

How can I assign a different Display Adapter to a program, other then the "Main Display" (which all programs default to, regardless of which monitor they actually appear on)???

Nvidia has something called "Nvidia Optimus" but is only available for mobile devices. But this is not available for desktop. Does Win10 have something like it where I can pick which GPU a program will use?

 

dGPU is recognized as GPU 0 and iGPU as GPU 1

I have a laptop with a dGPU. Will there be problems if the dGPU is recognized as GPU 0 (and iGPU as GPU 1) in Task Manager on a fresh install?

 

Windows 11 shows wrong iGPU's dedicated VRAM and Hardware reserved memory

I did set in UEFI BIOS that iGP's VRAM is 512MB. Firstly, it still received and showed that iGPU's VRAM was 512MB and Hardware reserved memory was around 600MB.

Recently, it has shown that my iGP's VRAM is 2GB and Hardware reserved memory is 2,1GB. So how can I fix this without resetting or reinstalling Windows or changing BIOS version? I tried resetting/reconfiguring BIOS settings (saved obviously); restarting/updating Windows to the latest version; reinstalling drivers but it hasn't been fixed.

Also, my iGPU's performance between 512MB VRAM and 2GB one is no difference.
