Videotoolbox with multiple devices

I'm using ffmpeg git on MacOS 10.13.1

In my system, I have a iGPU (HD630) and an AMD Vega64.
I can use videotoolbox to encode video on both GPU's but can't select which one to use.
When iGPU is enabled, this one is always used.
But when I disable the iGPU in bios, the Vega64 card is used.

I've encoded several video's and for h264, I want to use the HD630 iGPU because it produces better quality. But for HEVC, the Vega64 produces much beter quality and is 4 times faster.

So, it would be very nice if it is possible to switch between the available GPUS.

have you tried gfxCardStatus by Cody Krieger from
Does it work for you?

Thanks for your reply.
Tried the app but it doesn't launch because it's designed for MacBooks and I'm using an iMac (Hackintosh).

Well, it is an open-source utility, so maybe someone from hackintosh community can modify source code to run it on your hackintosh. Let us know about progress!
