Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

[jiffyslot]

I know that my screenshot you have shown does indicate that INTEL is being employed and not the GPU.
BUT in reality it is NOT. There's NO way my 3rd Gen CPU can transcode even HEVC or H264 source that quickly. Besides, look at IPG tool, iStat and that AMD Monitor App which shows that the CPU is almost IDLE and that the AMD GPU is busy Decoding AND Encoding. Also, note that it shows "INTEL" as green and NOT the CPU which it is indicating that it thinks it is using the IGPU.

I think it's the bug they refer to when they say "does not support AMG GPU" by which they mean it does not display that the AMD GPU is actually being utilised ? That is, they cannot distinguish which GPU is being utilised.

Have you tried turning OFF your IGPU and test ?

Thanks, and yep, the iGPU is off (iMP definitions, etc.) Would, you mind running a (Disc decode to .ISO test) with just VideoProc and "Activity Monitor" running with the main viewer, CPU usage, GPU History windows up front? I'd really like to know if it's a UI issue or something else. FWIW, the blue text in italics was from Digiarty tech support.

OMG - had to go into the attic to find a DVD and a DVD drive
Both CPU & GPU utilisation very low though it seems to be converting.
FPS is shown as ~600.
I don't think it's a GUI problem.

I know! It's nuts. I told them to email me when that feature is GPU supported. In the meantime, it's all Handbrake or Compressor. Has anyone out there tested one of these builds with the latest Media Composer? FWIW, I'm on Mojave on my 9900KS build 4-evah...

So I recently upgraded to 10.15.4 From Mojave and Installed Final Cut Pro's Latest Version. Unfortunately, It is very glitchy with 4k Footage and even VLC Player cannot play it. It works in Quicktime though, Following are my system specifications

Intel i7-4770K

Gigabyte Z97X Gaming 7 Motherboard

16GB (2x8GB) GSKill Ripjaws DDR3

Sapphire Pulse RX570 4GB

I am using Clover Bootloader, I have iGPU Off, SMBIOS is set to Mac Pro(For DRM Issues) and I have latest Lilu/WEG Installed. Can anyone help me because even iMovie works perfectly but Final Cut/VLC are glitchy as hell! Some 4k hevc files are working fine but some others are not
Thank You

Ideally yes.
But you can use other SMBIOS's.
For example, on my Ivy Bridge (i7-3770K) on Z77 chipset, I use iMacPro1,1 with CPUFriend kext and get fairly reasonable power management. I disable the IGPU.
It's not perfect but I can achieve HEVC encode and decode using the RX580 and very little CPU load when funning FCPX.

Hi, I'm fighting with hardware acceleration with my rx 580 as well. Turns out I have the exact same setup as you...any chance you'd share your efi folder?

Hi!, I've a system similar to you.
Check my EFI configuration (I'm using OpenCore instead Clover).

Geekbench 4 results: avg 138K OpenCL / avg 116K Metal
DRM: Safari OK (Netflix without issues), Music, Apple TV, etc. OK.
AirPlay: OK
HVEC: OK
H.264: OK
FCPX: No issues
USB: OK

My video card is a Gigabyte Radeon RX 580 G1 with 8GB, and I'm spoofing the ATY,Part/ATY,Card/ATY,Rom/Vendor/Device in conjunction with WEG (I include a copy from config.plist file with these configs, check the file config-with-vga-config.plist); I heard that the Sapphire are natively recognised by macOS (plus WEG), so maybe you'll not need it.

For better results, use the iMacPro1,1 SMBIOS (I've included these configuration in the attached zip).

Hope this helps you!

Depends on what you define as "hardware acceleration".
RX580 GUI hardware acceleration works fine.
RX580 "Rendering" in Apps video editors such FCPX works fine.
RX580 HEVC and H.264 decoding & encoding "requires some effort".

Then, there are App issues. Latest version of FCPX (10.4.8) screwed up HEVC Encode on RX580 on Catalina.
FCPX 10.4.6 on Mojave seems to be the most stable workable FCPX platform.
Others have said DaVinci Resolve works well for both HEVC & H.264 encode & decode on RX580.

Regarding my EFI, I have now moved to OpenCore Release 0.5.8 (attached).
Warning: if you do not know what is OpenCore, you have a lot of reading to do (good luck).

NOTE:
I turn OFF the IGPU in BIOS.
I use iMacPro1,1 SMBIOS (one of the "requires some effort" puzzle pieces).
I have a modded BIOS that has an NVMe EFI driver added (so that I can use an NVMe drive in a PCIe adapter).

familygw and macnb,

Thank you for posting your OpenCore configurations. I think we're chomping at the bit
in here, waiting for Sniki's new version. I'm also using Opencore 0.5.8 and looked through
your configurations.

I didn't see any of the patches equivalent to fix HPET from use of CorpNewt's SSDTTime.
Do you think those are not necessary?

Also, I noticed that you're using FakeSMC instead of VirtualSMC. Is that just for the sensors,
or did you find some other benefit? It seems like VirtualSMC is the only one supported as
we go forward.

Thanks again for any comments you may have.

Lisa

For my motherboard, did not need any patches in ACPI except the USB2 patch (EH01 & EH02).
I even disable the SAT0 to SATA patch - just cosmetic as macOS does not care.
In the Clover days, I had my own "fully cleaned" DSDT but for this motherboard, but with OC I don't use the DSDT at all and just need the EC, PLUG and NVMe SSDT's.
I can even boot Windows from OC.

Regarding FakeSMC, yes the only reason I use that instead of VirtualSMC is because I use iStat and VirtualSMC does not support it well with it's sensors. OC will support FakeSMC I'm pretty certain.

@familygw, I am looking to switch over to Open Core as well. How are your USB ports mapped? I did not see the AML fiile or a USB kext in your EFI folder.
