Your configuration is not as per the guide.View attachment 9579Hello everyone! I’m having issues with my **Gigabyte R9 270 GPU** on macOS Monterey. I’ve tried many solutions to get it working, but so far without success. The most I’ve achieved is native monitor resolution and a non-laggy interface, **but without Metal support**. I’ve attached my OpenCore EFI folder.
I looked in the windows device manager, kext ATYInjector deletedYour configuration is not as per the guide.
What's the native Device ID for the GPU?
Also, you shouldn't be using ATYInjector.kext.
As indicated in the GPU compatibility guide, you'll have to spoof the Device ID for R9 270. The closest match would be 6810.I looked in the windows device manager, kext ATYInjector deleted
I tried to put 0x6811 id in deviceproperties and the interface became laggy and the monitor resolution was removed (it was 1024x768 when the id was 0x6810 1366x768)

Well, that's because you did not follow the correct guide. Use the latest WEG kext and grab the sample SSDT for spoofing from here. Note that you'll have to use SSDT-DTGP as well.View attachment 9601
I fixed GPU by creating the correct SSDT-GPU-SPOOF, but this patch only worked with WhateverGreen version 1.5.1 (I learned this from a 3dogs1monkey guide on YouTube). Also, for some reason, the GPU name doesn't show up in "About This Mac," even though it displays correctly in other applications. how I can fix it? Attached my current EFI
