As we know, the Vega graphics cards have native support in macOS HighSierra and Mojave. emmm...and some glitch
But AMD uses a function called "SoftPowerPlayTable" to control the Vega cards.
"Soft" means it can be stored in the system and works well. (no need flashing the vbios after you modify it)
So I made this app to edit, build, and inject these control tables into macOS. And these are all based on a GUI interface.
You can control the Power/Frequency/Voltage/Fan Speed of your card(s) by using this app and Clover.
When you modify some settings, you can click the "Build Powerplay Table" button to create your own custom kext, or you can also click the "Generate share link" button to generate a url. And you can share the url with anyone who have also using VGTab, then they can use the same custom settings as you do.
When you are confused about the name of any setting, click on it to get more information.
I have already released this app about half a year ago (on a Chinese hackintosh forum). Why there is no English version? Because I am not good at English
(I'm Chinese).
