OK sure but every time I turn on iGPU Multi-monitor in my setup, literally nothing works. I get kernel issues or runtime allocation issues. With the multi monitor disabled I am at least able to boot/install. I have tried so many different configurations at this point. Even people who have my exact motherboard and CPU. I'm starting to thing its some other issue, maybe RAM.I agree with this statement. Apple is definitely using some kind of hardware acceleration on the iMac Pro. Maybe it's custom Xeon with Quick Sync, or they are using decode/encode logic in AMD's Vega, called UVD and VCE.
But I never heard that this is a case for RX580 or other cards from iMac. The same time people are complaining about H264 encoding on iMac Pro, because usual iMac with Quick Sync do it faster. So enabling hardware acceleration is a good idea.
If I disable iGPU, I can boot but I have freezing issues unless if I use the correct combination of swapID/WE/Lilu etc. to get it to work. And that just seems contrary to what other people are able to achieve with my same setup. I literally don't understand how people have gotten this to work so easily
