Hi, I've been running a hack for quite some time, having problems here and there. Now, I've settled on a config (i5 6500, but wil be changing to i7 7700 soon) but I keep struggling with performance still.

The graphics and the UI is extremely choppy (GTX 1060 6gb, 16GB RAM, 256GB AHCI SSD + 1TB 7200rpm HDD).

Windows in Finder are lagging when resizing and moving, Safari is struggling when playing 1080p videos etc. I was wondering, if I'm doing anything wrong.

The other thing is, my Airplay mirroring is not working. I've got a 2015 TV and all I get is a black screen when I try to Airplay my hack display.

I'm attaching screenshots of my Clover config + my kexts + 3 videos (video I, video II, video III), demonstrating the choppiness while playing youtube. Besides, the CPU is stressed almost all the time, while the Intel GPU does nothing. I'm running the latest macOS + latest NVIDIA drivers.

Any suggestions or help is greatly appreciated! Would really like my hack to perform as intended...
