9470m: System runs slow with Open Core bootloader

[pro]

you have working EFI folder. How did you get this message?
I have only replaced ssdt- igpu.aml in that EFI (one from 840g1 config it has 1366*768 lcd) and it works good. Also need to set correct frame buffer.
The guide is here: https://dortania.github.io/GPU-Buyers-Guide/modern-gpus/intel-gpu.html#native-intel-igpus

I adjusted it as in the attached picture but could not reach the solution.

 

[pro]

Try to set AAPL,ig-platform-id 02006601

 

[pro]

And you can add this ssdt

Hi pro,

I tried both but unfortunately it didn't work. Since I am using a 1600x900 screen, I have to use SSDT-IGPUH.aml file.

 

[pro]

The file ssdt-igpu from RehabMan has different types of frame buffer descriptions for normal res and hi res screen inside one file . Try to check if you enter the right one to opencore config.

make sure you are using the latest version of OpenCore, and make sure to replace all files in efi with new ones
