No idea. It seems to be percentage based more than fixed for whatever
reason. I built emacs 27 w/ -g3 -O2

Mine are fairly consistent. I imagine hitting thermal would hurt
though and Intel macs love to do that.

What isn't consistent is typing experience. There are times when it's
just like molasses but I can't necessarily reproduce that with
benchmarks. I wonder if the separate threaded IO from the mac port
helps make things feel more consistent in some way.

It'd be great to try an emacs-28 with the 27+flicker patch rendering.
I'd be curious how that'd feel w/ native comp. Maybe that'd make
enough of a difference for me on this screen.

Thanks,

Aaron
