Windows 10: does iGPU usage hurt performance?

I wanted 3 displays so I bought a FirePRO. Turns out even though it's rated for 3 simultaneous displays, it only works if you get some special adapter which I never did figure out what it is. So currently my only option is to run 2 displays from the FirePRO and 1 from the DVI port of the motherboard under dual pci/igpu settings in the BIOS. Does this hurt performance?

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?

List of people who buy any Intel CPU for it's integrated graphics to game on them. You use the iGPU when you don't have choice , no one really goes out of their way to game on them.

*Laugh :laugh:

Worse , not by a huge amount but enough the render them useless.

If the iGPU were an IRIS, I'd wager the list would be extensive because it would put up a decent fight. But hey, management choices, I guess *Oh Well hwell:
