Hello @nartcan, sorry for the late answer. I've been very busy the last couple of weeks.
I've upgraded my Radeon HD4870 and replaced it with a R9 270X card.
I solved the 3D acceleration problems by reinstalling my computer.
When it comes to installing hackintosh it's usually (in my experience) the kernel that is causing problems. But if you're certain that your graphics is causing problems I would recommend checking if you need GraphicsEnabler or not. Usually HD cards like mine (also R-Series) does. If you want help I will need you to be more specific and include things like: Bootflags, kernel, specs on your PC, errors et.c. A good tip is including your computer specifications in your signature like i have.
