iATKOS Inside: Nvidia UI freezes and lags (High Sierra)

Nvidia UI freezes and lags (High Sierra)

Hi everyone.

First thank you all for sharing your experiences here, it was really helpful and made things a lot easier for me building my hackintosh.

So I'm using an Nvidia GTX 1070 Ti GPU (with Gigabyte Z390 Pro WiFi & i7 8700K), and hardware acceleration seems to be working fine.
But there's a weird issue with the UI. Every now and then the interface would freeze a little bit (typically 1-2 seconds) every time I do any of the following:

Quit an app
Close a Safari tab
Sutting down / restarting
+ other instances...

I tried:

Installing the drivers through this script: https://github.com/Benjamin-Dobell/nvidia-update
Disabling the acceleration for Safari solves the freeze there, but it's also not a real solution of course, since the GPU isn't fully utilized

Couldn't really put my finger on what solved the issue there, but I tried a similar config anyway. It's also a different Intel generation.
Disabling/enabling iGPU

And none of them worked.

I'm using these drivers:
