UHD Graphics 630 performance problems on High Sierra

[bukilj]

Hello everyone , finally i built my first computer yesterday for development purpose.
Reading carefully other builds and guides in this forum i successfully installed High Sierra 10.13.6

My computer parts are :

Motherboard : Gigabyte Z370 HD3P
RAM : Corsair 8 GB DDR4 2.4 mhz
Processor : Intel i3 8100
Graphics : UHD Graphics 630
SSD : 250GB

After that i run MultiBeast configuration like this :

But the problems started with graphics and this time i don't want to change a lot of things on config.plist and efi folder like i did last time and crashed almost everything so i did a fresh install again.

Now first glitches i see when i enter password to go on High Sierra
When i open Launchpad it goes soo slowly and it takes 5 seconds to open e.x (folder Other) on Launchpad.
In safari browser sometimes my tabs buttons become black.

I added latest lilu.kext and WhateverGreen.kext on my drive / library / extensions but still see the problem with glitches and very slow Launchpad

When i click about this Mac it shows
Intel UHD Graphics 630 1536 MB

I am uploading my EFI Folder please can you help me with any fixed to make my computer more fast.
The only modification i did on config.plist was changing the System Definition from 14.2 to 18.1.
