I've been tweaking and making progress towards improving 4k performance on my Intel UHD 620 IGPU. I was able to get DisplayPort over Thunderbolt working with my 32" 4k monitor @ 60.00Hz. At first performance was sluggish until I found out about framebuffer-unifiedmem and noticed a significant improvement once I set it to 2048 MB. But still I feel some sluggishness especially in motion/animations, eg: moving to different spaces in mission control, etc. I tried turning on "reduce transparency" in System Preferences -> Accessibility -> Display, it kind of helped but not significantly.
I have verified that in my BIOS settings the DVMT Pre-Allocated is set to max (64MB) as well as DVMT Total Gfx Mem (256M), so I guess I don't need to use framebuffer-stolenmem and framebuffer-fbmem? Anyway I tried to use them but macOS freezes during post-BOOT initialization when I enable them via framebuffer-patch-enable, so I had to remove framebuffer-patch-enable in order to disable those two.
My config.plist file is attached.
My system:
Any advice is appreciated, thanks.
P.S.: All I've accomplished so far was done by following WhateverGreen's Intel HD guide and also this other guide over here.
