5675c el capitan screen flicking,bad peformance

Hi,all
I install El Capitan on my computer under 'Installation Guide',here is my main equipment:
i5-5675c
asus h97i-plus
But the visual effect is not good,and I think osx doesn't drive the Iris pro 6200 graphics well.
So,is there a way to solve this,or some patchs?
Thanks.

Try downloading the 6200 SSDT from here. You'll open the ZIP and put SSDT-1.aml into EFI/CLOVER/ACPI/patched/ and then reboot.

Also you might need to experiment a bit with the IGP settings in BIOS. Minimum size perhaps 64M, 96M, 128M, or 256M, and Aperture size 128M-512M. I usually start with 64 minimum 256 aperture, but it depends a bit on the machine and monitor/resolution I think.

I have installed 6200 SSDT as your said,and set the IGPU buffer in BIOS.
But nothing is changed,it is still bad.

Just want to be sure the SSDT took effect. Get a copy of IORegistryExplorer, run it, and do a search for GFX0. Select that on the left and check what it says on the right under AAPL,ig-platform-id.

There is no GFX0 in IORegistryExplorer.
But in IGPU@2 AAPL,ig-platform-id is <02 00 22 16>

 

[ammulder]

OK, that's right.

How is your monitor connected?

 

[jvjvlglg]

Dvi port

There is no GFX0 in IORegistryExplorer.

Attach IOReg/File/Save a Copy As...

Here is my ioreg file,thanks.

I changed the ig-platform-id to <00 00 22 16>,and different kinds of buffer size in BIOS,it is still bad.
