Intel® Iris Graphics 6100 video acceleration

[zainpro]

I installed High Sierra using multibeast and all is working good except for the video that is a bit shaky particularly when I play HD movies.
I have the following CPU and graphics, which is exactly the same as the one of the MacBook Pro "Core i7" 3.1 13-Inch (Early 2015 Retina Display)

CPU: Intel Core i7-5557U Broadwell architecture.
Processor Graphics: Intel® Iris Graphics 6100

I installed the “Intel graphics Fixup” and I wonder if this is the problem...
My question is do I need “Intel graphics Fixup”?
Do I need to uninstall it for better performance? How do I proceed please?
Do need to install a kext or drivers for it to work? or it will come with the osx directly?

Thanks advance

Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

@RehabMan thanks for you direction. I went through the documents you suggested but unfortunately I could not find how to resolve it and I do not want to mess around what I have been building for weeks.
All in this system is working properly except for the video that needs a bit of a fix. Video works fine but it is only when I play 1080p or 4k movies that loses up a few frames. I would like to see it as smooth as possible.

Could you please be more specific on what I have change considering cpu and graphics natively supported?

I did my homework going through the guide in detail to fix graphics:
Checked Bios settings, CSM enable, VD-t disabled, Secure boot disabled, fast boot disabled, etc.
Checked DVMT-prealloc set as 64MB.

1- I did not find was DEP where can I find t?
2- I have installed Lilu.kext and IntelGraphicsFixup.kext in /Library/Extensions.
Just to confirm: Do I have to add “ ig-platform-id=0x16260006 ” to Volumes/EFI/EFI/CLOVER/config.plist and I am done?

No problem reporting files attached.
Read post #2. Again. Carefully.

There you go

There you go

EFI/Clover is missing.
Your ioreg shows you're injecting ig-platform-id 0x59120000. 0x59120000 is valid for KabyLake, but invalid for Broadwell.

I changed to 0x16260006 using clover configurator but now it is not booting up...
clover is up there now.

You should try other ig-platform-id values...
Keep in mind 0x16260006 does not have the 0306 connector.
Also, your ioreg shows no Intel MEI on the PCIe bus. It is required.

Thanks, here my questions:
- How do I get an ioreg list to check IMEI and see if I fixed my Bios, before I continue doing any test, please?
- What range of values for ig-platform-id should I try according to your suggestion
- I reset bios trying to fix the problem but nothing fixed. Now I have to find a flash to fix it! I do not know which one to get
- How can I tell if I have a ES/QS cpu?
- I wonder how could I boot os x before without IMEI? Was'nt there one present at that time to be able to operate? Now I cannot even boot with any of my backups!
