I accidentally found why (AMD GPU?) Hackintoshes don't look as smooth as real Macs

IOAcceleratorFamily2 Variable Refresh Rate is disabled in the AMD drivers (not sure about NVIDIA and Intel) because it is broken. By fixing it, the UI rendering becomes as smooth as it is on real Macs.

Part of the work: ChefKissInc/NootedRed@3e7ee58

However it needs more work before I can enable it unconditionally. I outlined why in the commit's description.

EDIT: For clarification, this isn't a feature exclusive to VRR displays.
