gtx 950 glitches

[arthur4002]

i have successfully installed high Sierra 10.13 (17A405) but my graphics card is lagging so much, I have installed Nvidia web drivers 378.10.10.10.15.121 (and enabled in clover at system parameters) also have lilu.kext and whatevergreen.kext but still having visual glitches

also my monitor resolution is 1600x900 but only shows 1280x1024
and About this Mac only shows Nvidia chip model 5 MB

I'm attaching my config.plist, can someone help me?
