Multiple GPUs without SLI or crossfire

[Hoshire]

So i've recently got myself a new workstation,with TR 2950X and Radeon PRO WX2100.

I decided that I might game on it sometimes so i got myself a 350$ brand new VEGA 56 from XFX.

After install that GPU into the system it didn't work with Radeon PRO drivers first,so i installed driver for VEGA 56 and my WX2100 stopped working.

However after another reboot and reinstallation of Radeon Pro drivers both GPUs showed up in the device manager but still can't figure out how to designate heavy 3D rendering tasks to vega and 2d tasks to wx2100.

What i want to achieve is something like what happened in a laptop where a dedicated GPU renders frames and send it back to the integrated GPU and display it.Here I want games to be run on vega56 and displayed via wx2100

my first queston is why?
the vega 56 can do 2d...
ever since 1997 and slightly back gpu's have been able to do 2d and 3d.
there wouldn't really be any benefit with your method, to be fair it could/would probably introduce more input lagg.

also the wx2100 won't look any better compared to the vega 56

So it might be better just to pull that wx2100 out of the box?

But some pro applications run faster on wx2100 and it might be more stable in case like Photoshop or solidworks and stuff like that

the thing is that the wx2100 is designed for CAD software and workloads.
the vega 56 is deisgned for 3d tasks like videogames.
you could leave both in and configure them manually in the software... but that could be a huge pain.

in some games, yes, they allow you to decide which GPU you would like it to run on, like world of warcraft, but in most games they just use whatever your monitor is plugged in. In laptops they can use windows features to run program with high-performance GPU or power-saving GPU but in my case both high-performance GPU and power-saving GPU are shown as WX2100

hmm i don't know then, but as i said it's probably gonna be a pain in the ass to try and get multiple gpu's running.
i would just look at what you need most, workstation performance or gaming.

I figured out some kinda solution.

Maybe I could run a virtual machine and passthrough vega to the VM and run games on VM.

that would be an interesting project, but could potentially be really hard to actually get working properly, but it would surely be a nice project.
