Switch Between Intel iGPU and AMD dGPU for different tasks

[Sybaris_Caesar]

Can I do it like this guy here?

I wanna do everyday tasks like web browsing and sh¡t with my iGPU which is connected via VGA and then game on the dGPU like always which is connected via HDMI.

Is it even feasible? Or worth it? I thought maybe it'll save me some electricity if dGPU isn't in use. Though that's not a high concern.

Sorry if it's already asked and answered.

It only works with DirectX apps, for Vulkan and OpenGL you need game's settings.
Also if you "move" the app to the HDMI monitor, that also counts.

I know that much. But what's the prerequisite? Enable igpu on bios? Install Intel driver?

I only wanna do it for a) browsers, b) media players etc.

P.s. I have only one monitor. iGPU and dGPU are connected to same monitor. I can quickly switch input from the osd.

Since there is no Hybrid driver like there is for laptops the only thing you can attempt to do is yes enable IGP install the driver and switch inputs. If there is a way to set hardware affinity i am not sure

I don't know how it works on the AMD side, but with nVidia cards, the desktop driver is still a hybrid driver. So you connect your monitor just to the iGPU, and then select the apps(games) you want to use the dGPU using the method posted above. Windows will use the dGPU to render the games you tell it to, but send the output through the iGPU's to the monitor.

It's universal on the latest Windows 10, but as I said, only for DirectX (99% of programs).

Well tried it. Enabled iGPU via bios. Boot into Windows. Problem is it's eyefinity like situation.

Main display is dGPU and output is 1. Changing input to iGPU identifies as 2.

All the desktop shortcuts are in 1. 2 has identical start button and taskbar icons but pressing on anything creates the window in 1.

Not to mention Windows doesn't identify iGPU as power saving GPU in Graphics Settings.

The 'why" question comes immediately to mind. I mean on a lappie, this makes great sense because it will extend battery life. laptops do this by default but you can over ride the defaults on a per program basis. However, with two monitors, this is a normal thang whereby the discrete card is used on the "gaming monitor and the iGP is connected to the 2nd monitor for utilities, browsing, etc.
