Hello to everyone here .. I am new to ryzentosh .. for a year now I use hackintosh high Sierra on my spare pc ( Intel x5460- 8gb ram - and gt 630 ) but I’m bored the glitches on graphics because on high sierra doesn’t support my gpu ,, so yesterday I install the high Sierra on my main pc ( ryzen 7 2700x -b450 gaming gigabyte -16 gb ram 3000hz- Vega 64 ) from xlnc usb installer .. I make fast and easy .. everything work perfect . The lan-audio- gpu run on 1080p 144hz .. but the problem is when I open for check the multicraft game I see low FPS and very high usage of cpu , it’s about 90-95%.. I search on internet and I see must install AMD VANILLA PATCH - AMD POWER GADGET KEXT and SMCAMDProccessor... the point is that I don’t know how to install... with Intel I don’t had problems so I do not try something with patches or kexs .. but now I need to learn ,,, thank you

The AMD Ryzen Powermanagement kext does not do anything in that regard.

If you want to fix gaming performance you have to switch the last two kernel patches. Disable the kernel patch algrey - mtrr_update_action - fix PAT and enable in turn the kernel patch Shaneee - mtrr_update_action - fix PAT.

If you are not very confident about doing that I'd recommend to first test the new config with an USB stick.

How and from where I disable the kernel patch ? Thank you

Those are the patches you had to add to your config.plist when you built your EFI.

The bootable usb I just make restore from file of xlnc.. so I don’t build it and I don’t know ...so I open the config.plist with clover configurator and disable the patches ?

Clover is not supported anymore, can't help you with that.

Clover isn't supported nor is it propperly updated for out patches. Your install method also isn't supported.
The high CPU usage could be from the config being configured wrong or from Spotlight scanning your drives.

Also don't use my PAT patch as you've got a Nvidia GPU, it doesn't work for them.

Yes that's normal. macOS doesn't have the strings for AMD as they don't use them. It's purely cosmetic. If you run sysctl -a machdep.cpu.brand_string in Terminal you'll see your AMD CPU, for example here's mine,

Code:
shaneee@Shaneees-RyzenPro ~ % sysctl -a machdep.cpu.brand_string
machdep.cpu.brand_string: AMD Ryzen 5 5600X 6-Core Processor

Update your patches from GitHub and you’ll find it.

Download the patches.plist and open it with a plist editor. Along side it open your config. In your config delete Kernel -> Patches and then copy Kernel -> Patches from the downloaded patches.plist into your config under Kernel.

No. The key stays as Enabled. You need to change the Value from True to False.
