So how would you recommend I fix my problems? Sorry to be such a noob but if you could spell it out that would be a big help!

Add Change PEGP to GFX0 from post_install.plist. Same with change _DSM to XDSM. You can just drag and drop. Then you will need to make a SSDT-GFX0 injector. Look at https://github.com/VoiletDragon/Z77-DS3H-Clover-Hotpatch-Patches

Don't use Clover Configurator to add ACPI, DSDT, Patches to config it will destroy the config

I don't have this problem, but I have seen many people talking about DSDT, patches and other stuff to have better stability than doing it inside Clover. Is it true? If so, is there a Noob Friendly guide which I can follow to do my patches. I always feel my Hackintosh isn't up to desired performance, I am hoping this will iron out most of it. Most of the build guides end with a basic post installation and finishing everything in clover.

I don't bother with DSDTs no more. All of my Desktops including both Servers I have are on Clover hot patch with a set of SSDTs.

Has anyone been able to resolve this? I am having the same issue. I tried Replacing PEGP with GFX0 as well as trying iMac 14,2 SMBIOS.

 

[shala6]

Just wondering if anyone would be so kind as to check out my ioreg and Clover folders as well since I'm having the same problem. Most of the patches are from "Gigabyte-GA-Z77X-macOS-Install" on github (don't think I could edit the SSDT.aml files myself).

hi, same problem here, with evga gtx 560, have artifacts everywhere after a while, if i put the machine to sleep artifacts are completely gone after wake up for a few minutes and the artifacts come again.
tried official drivers and nvidia webdrivers, but the problem continues with both drivers. in sierra or el capitan i didnt have any artifacts.
im out of ideas

 

[CrashMidnick]

Same problem with standard GTX 660. Driver problem in High Sierra = we need to wait until next release and hope that Apple will fix this. Or we will need to use web drivers...

Same here and out of ideas. Tried changing the system id from iMac 14.2 to 13.2, tried disabling inject intel in the Clover configurator, tried both Mac OS and nVidia Web drivers.
