GPU Performance Improved

Ran a Geekbench 5 Metal test before and after patching and it went from 49525 to 50406. Seriously, it's amazing that patching can squeeze out more performance! Thanks for your hard work!
My configuration is the same as you. Can you share your EFI?

Sorry for the late reply, I had a busy week at work. I'll see what I can do, will have to edit out my serial and motherboard id and stuff. But it's a great hardware combo, it runs rock solid. I'll message you once I got round to it (or are you REALLY waiting on it?) ;)

Over the past few days we’ve been looking into why the GPU performance was lower on an AMD hackintosh and narrowed it down to one patch. After many tests and reboots we can now say the issue has been solved. Patches have been updated on the AMD OS X GitHub.

Oh. My. Goodness.

I knew that my Radeon 7 was capable of a great deal more performance.
But despite my best efforts, benchmarks like Unigine Heaven, it was scoring around 30-40fps.
This patch has easily doubled the frame rate.

Excellent work.

This is amazing!!!

Loading WoW and using Activity Monitor I can notice that all cores are being used a bit as expected but the GPU load was around 50% for the 480 and 30% for the 5700, with about 30 FPS in both cases. That was catastrophic compared to Windows. Even changing settings to lowest or not the difference was minimal.

Now after this patch performance is incredibly better, about matching what I have on Windows. These results are based on the 480 as I don't have the 5700 anymore.

THANK YOU very much for this. I only use Windows to game and this may actually finally allow me to play on the Mac again.

Also, DP audio issues as noted by others, but I don't care, I'll use a USB headset anyway.

--Edit--
Forgot to mention one thing. On certain areas of OS X I can notice a considerable improvement as well. For example, clicking on the "Downloads" folder for example with the "Fan" option, it is noticeable smoother than before. This is something I had noticed when comparing to my real Mac, but couldn't pinpoint what it was.

After the patch this is basically the same as the Mac. I'm very excited to figure which other areas of the OS may be affected by this.

My geekbench metal score has gone from 54638 to 48327 after upgrading my RX 580 to a RX 5600XT :(. Everything else is way faster, is this normal? This is on the new patches btw.

Don't worry about the GB score. It's not indicative of real world performance.

How can I disable this patch? I'm getting a lot of Graphics Kernel crashes (Graphics kernel error: 0xfffffffc) lately (Big Sur 11.1b1) and I feel it might be related.

@rajovo Github patches include both the original and my updated one. The default one is the original. Just change the Enabled value of the kernel patch. Make sure you've got both before disabling the new one as you wont be able to boot without it.

I've noticed a huge difference with these patches. Much better overall performance in both OpenCL and OpenGL. This is a major breakthrough!

I've noticed there is a difference between the 38 k/patch and 39 k/patch versions. The 38 patch boosted the card over the normal levels as compared to windows. The latest 39 patch brings it right where it should be for a comparable Intel based Hackintosh.

I haven't noticed much difference in the CPU scores or performance levels between the 38 and 39 k/patches.

I think I got a monster 5900X the single core results are incredible, factory auto settings in bios. I'm contemplating the bio upgrade to F11 to see if ti changes any performance levels.

OMG the 5900x single core score is almost twice of my 3900x's 1294 :-o

@Gigamaxx The experimental patches were merged into the base OpenCore branch. This contains both the old and the new patch. The old one is enabled by default as the one with better performance causes issues with HDMI/DP Audio. You can disable Algrey's and enable mine in the config.

I didn't realize you could enable/disable patches like this, that's so cool!

@Shaneee, any idea why my GPU memory stays at 2 GHz at all times (according to iStat and the fan noise)? GPU downclocks alright, VRAM doesn't. It used to do so. I have removed Radeonboost but that didn't fix it. The card (RX580) downclocks both GPU and VRAM in Windows as expected. Thanks!

@rajovo I'm not sure. Does this happen with the old patch too?
Yes. It's not your patch's fault. Hm, IIRC I was getting proper VRAM downclocking at least in Catalina. Now I'm stuck with VRAM running at full 2 GHz at all times, with any combination of your, algrey's patch and Radeonboost.kext. I wouldn't mind that much but it does keep the fans audibly spinning, which is annyoing.
