[SOLVED] Use of GPU with Display connected to IGPU?

[Rheaun6]

System is Win 10 Pro Asrock Steel Legend Z390, I5 9600K - HD630 enabled (Monitor is connected to motherboard Displayport) and Radeon RX5500 XT no cables plugged in card.
I stumbled accross this setup by trying to enable Corel Painter Brush Accelaration but my GPU is not compatible it seems. However I've compared the performance of using enabled IGPU and plugging through motherboard versus using the PCIE card ports.
The performance in-game is hard to tell apart but there is noticeable Task Manager Usage difference; Using both IGPU and GPU I have 35 -75CPU, 30 IGPU and 100! GPU versus 65-75 both CPU and GPU with disabled IGPU.
Included a pic of what I mean by the usage when plugged into IGPU : https://www.facebook.com/photo.php?fbid=558018758442025&set=pb.100027017173462.-2207520000..&type=3
I thought the IGPU didn\t use the GPU, can someone elaborate what is happening?

5500XT is significantly faster. Have you installed Adrenaline drivers for it?

What game are you comparing?

Fyi, PCIe graphics cards don't route video through the motherboard so you would connect video cable directly to the graphics card as you have done. Not sure what you're seeing there between the GPU and iGPU but there's no combined performance to be had between them, it's one or the other depending where the cable is connected to. iGPU is the graphics processor unit inside the CPU, performance equivalent to the old GTX560.

No it is using the GPU, its usage goes from 0 to 100 when the game starts and the graphics look like they are using the GPU but haven't tried pulling out the card but no cables plugged in it. Games I tried quickly are Heroes & Generals and Cuisine Royale.
Have read that upcoming PCs can use PCIE GPUs without plugging in by using Intel Thunderbolt but I'm only using IGPU, Tunderbolt is disabled but available on the motherboard.
Does anyone understand the GPU and IGPU usage?

Of course everything up-to-date.
