Help needed for DSDT edit for Nvidia 310m Graphics

[jamzmoby]

Hi i'm having grief trying to get the full graphics acceleration working on my latest project. 
Primarily the system i have is based on a laptop motherboard but its classed as an All-in-one-Desktop PC so am unsure which category it comes into.. The system spec are:

Samsung DP-U200
Dual-core Pentium T4400 2.2Ghz Penryn
Nvidia Geforce G310m onboard graphics 512mb
Legacy Boot
Yosemite 10.10.3
Clover boot loader

The problem i'm having is getting the full use of graphics. Google chrome is unusable because the screen keeps scrolling but safari is usable but glitchy and slow. I've tried using the nvidia web drivers and that no different and adding NVCAP values to my config file.
I've extracted my DSDT using Linux but i'm unsure as to where or what to patch exactly. 

Any ideas or pointers to the correct direction for editing my DSDT to get this fully working would be appreciated.

Thank you in advance.

 

I've enclosed my DSDT for anybody to have a look at.
