Hi, I got a new pc lately and after installing after effects 2021 it noticed it lags as hell!

I thought it's from 2021 and updated after effects to 2022 latest version but there's no differences!

I have a decent pc with following specs:

EVGA RTX 3090ti OC

Intel i9 12th gen 12900K

64GB DDR5 Ram

and 2TB NVME which after effects and footages are on.

Here's a video of lag :

I even reinstalled windows 11 and updated all the drivers to latest.

Also noticed after effects only uses ~10% of my cpu and ~20% of my GPU.

I'd try resetting preferences:

 press Ctrl+Alt+Shift (Windows) or Option+Command+Shift (Mac OS) while starting After Effects to restore default preferences settings

Also go to Edit/Purge All Memory and Disk Cache.

Hope that it helps.
