Screen refreshing/flickering everytime on OS X Yosemite

Hey there,

I'm pretty new to this "Hackintosh Thing". But finnaly I've dual booted Windows with OS X Yosemite.

When the Login Screen appears and I log in to my Mac there are big, black bars crossing the screen.

It looks a bit like this (https://www.youtube.com/watch?v=994_z22OMA0) <- Not my Video.

 

He posted a link to another forum, which helped him. They said I should install the Nvidia Web Driver. I did. Nothing changed.

Same is in Skype and XCode. The Messages on a Chat windows are refreshing.

 

I configured that when the system boots it automaticly runs a tool called "Beamof". Without it the performance is terrible.

 

This is my Hardware Specs:

12 GB RAM DDR

Nvidia geforce GTX 770

Some AMD Procsessor

 

And here is my org.chameleon.Boot.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>EthernetBuiltIn</key>
	<string>Yes</string>
	<key>Graphics Mode</key>
	<string>1920x1080x32</string>
	<key>HDAEnabler</key>
	<string>Yes</string>
	<key>HDEFLayoutID</key>
	<string>01000000</string>
	<key>Kernel Flags</key>
	<string>npci=0x3000 nvda_drv=1 nv_disable=1 GraphicsEnabler=No </string>
	<key>KeyLayout</key>
	<string>mac-de</string>
	<key>SkipNvidiaGfx</key>
	<string>Yes</string>
</dict>
</plist>

I'm sorry for my bad englisch :0.

With best regards Levin :)

 

//EDIT

If I want to for example change the background image, the Picture preview keeps white. Same for User Profile Picture.

And if I have a look at System Report, it says that I have 0 MB of VRam.(My Graphics Card should have 2GB)

Even if I want to use Photoshop it says, I don't have enough VRam

Okay I've fixed it on my own.

 

1. I installed Hackintosh completely new on my partition.

2. In the Yosemite Installer Configuration I enabled: "Backup Grahic Kext"

3. After I finished the Installation I had the old Nvidia kext in /Backup. I installed them with Kext Wizzard and restarted with 

restarted with these bootflags: npci=0x3000 dart=0 nvda_drv=1

And also GE=Yes

 

Now I'm enjoying full vRam and don't need to use the beamof tool. The preview images are shown too and the system has

as so smooth performance now.  :thumbsup_anim:
