(Noob) Graphics Flickering/Slow, please help

[AriIQ]

I just put together my first hackintosh, and everything was going fine up until post-installation. Pretty much anytime there is an animation on my screen, it flickers. It happens when typing, when scrolling, when a banner-ad loads comes on screen. etc.
I have downloaded the nvidia webdrivers, but they always switch back to the OSX default graphics when I restart. I'm missing "InjectNvidia" and "GraphicsEnabler" from my config, so I followed the instructions for problem 6 in this thread:
https://www.tonymacx86.com/threads/solving-nvidia-driver-install-loading-problems.161256/ but I still am reverted to the default driver and still have no "InjectNvidia" or "GraphicsEnabler"

Please help, I am beyond frustrated as I have been trying to fix this for hours at this point.

GB-Z170x-UD3 Ultra
GeForce GTX 950

I'm a total noob, so I likely need my hand held instruction-wise.
All help is greatly appreciated.
