With the rx 480 card responds muchisimo better than with the nvidia.Es faster everything. Before I had a gtx 980 ti but when maximizing a window or minimizing trying to make it bigger or smaller adjusted with the mouse, it was slow as slow. Now with the rx this has improved a lot, although the final cut, logic and various programs if you try to make the window bigger or smaller is slow. How late! This happens to someone and there is a solution?
It feels like you do have OpenCL acceleration, I wouldn't be surpised if that works out of the box (the AMD9500Controller has support for the RX480 without changing it).

Are you sure you added the right ID to the AMDRadeonX4100.kext? Also after editing it make sure you clear your cache with:
sudo touch /System/Library/Extensions

and then a reboot

I just updated, restarted (lost acceleration), reapplied the patches to the AMD9500Controller and AMDRadeonX4100 kexts, refreshed the kext cache and restarted. That was it.
did you instal AGDPfix again to make it work?

Did you compare the Kexts from 10.12.2 to the 10.12.3 ones and if so were there any differences? I am asking because if there's no difference other than the alterations to get full acceleration, I can just back up 10.12.2 kexts and re-implement them easily using KextUtility in 10.12.3.

Didn't compare, so I couldn't tell for sure. But since the patching process was the same I doubt there were any changes.

Updated the BIOS to F21 on my Gigabyte Designare. Everything works, still have full acceleration but now I can't boot with Inject ATI without a kernel panic. I can still boot with Inject Intel + Inject ATI but even while on RX 480 graphics it's somewhat choppy again even though it's benchmarking the same.

Any ideas?

Wanna report that I just success on my Gigabyte RX 480 4GB, with ASUS Z170-E motherboard.
with full acceleration, passed Unigine Valley Benchmark Ultra.

This video helped me a lot, it help me set up bios and everything step by step, and I highly recommend to watch it before you go.

But still one thing annoying:
I have to set iGFX as primary graphic output (output video from motherboard), and enable multi-motitor.
So I suppose to connect both HDMI Monitor 1 on MB and DP Monitor 2 on GPU.
If I connect both: boot up well, but I have to unplug the HDMI on MB and reset display setting every time of boot
If I connect only DP, the moniter won't show the Clover boot loader, monitor turn on when Sierra starts, I cannot dual boot to Windows in this way
If I connect to HDMI on MB only: I cannot see anything, but apparently system started with Sierra OS.

Any solution there?

MacOS can handle multiple GPU usage from within macOS - it does not require additional connections like Crossfire in windows does. It is even possible to use multiple AMD and nvidia GPUs together - although I wouldn't advise this as you are unable to assign individual cards to specific applications.

Multiple GPU installation will improve performance and that is why many folk use two 280X cards for FCPX
Thank you Adrian B. Does someone mix up a 280X with a RX 480 8 go ? How it performs ?

I would stick with HD7970/R9 280X at this point in time on any primary build. The new RX range is fine for those wishing to be early adopters using a second machine for testing. I wouldn't do this for an actual production machine as you will be in for a rough ride with early adopter hardware.

I recommend using either a single 7970 or two 7970 GPUs in any given build. The same with the R9 280X, I am still using Yosemite for FCPX. :thumbup:
