After Effects 2022 is the slowest version launched. Freezes a lot, the preview is unbearable even on light compositions (i7-6800k, Geforce 1070 8g, 64gb RAM, 2 SSDs (one for the software, one entirely for cache).

hey, I have almost the same specs, and almost the same usage! yeah, AE only scales linearly with RAM, clock speeds, and core count now that multiframe exists. unfortunately, those cards with many cores have slower clock speeds and smaller transistor counts at times. I only have 32 gigs of RAM, so that means I can playback a little more than half of what you can.
GPU does next to nothing. if you do use it it will be blisteringly fast, but hitch and make the UI unusable whenever the preview and AI are both showing (almost always.)
I have a post with a number of others who have similar grievances. also commenting here to boost popularity because we're seeing the same thing with the same (almost) computer.
