MacOS Sierra Graphics Animations Laggy/Flickering

Installed Macos sierra on my lenovo k450 - (I7-4770,12gbRam,GTX650 2GB)

The animations are laggy and flickering.When i boot into macos at the lock screen it starts to flicker 3 times before i get to the desktop,some weird lines pop up,using chrome is extremely bad,i cant even see the page i am browsing.I have tried to install the nvidia web driver which installed succesfully but after restart the logo at the top seems to disapper? The panel in prefernces doesnt wanna load up??

The boot flags i am using are -x & kext-dev=1 other wise it gets stuck at apple logo and restarts.Tried using the inject Nvidia and nv_disable=1 and someother which i cant remember

Can somebody Please Help Me?

I used couple of vids to create my installer I used some .raw file and extracted it to my usb using rufus,clover works and macos sierra works fine,just this weird glitching graphics problem.

I have a dedicated Nvidia GTX 650 2GB (I know this is old but it is better than onboard intel which somepeople are using)

Thanks for reading this,
