Improve Performance with 4K+ footage
I am experiencing painfully slow UI lag / app hanging when trying to work with comps and footage at or above 4k at full quality. Even empty comps slow down the app dramatically unless I change the quality of the viewer to 50% or lower.
I've tried turning off hardware acceleration and it seems to help for a short time but eventually the application just starts hanging. It's terrible. Trying to use the Tracker tool on 4K+ footage is painfully slow with the app hanging for 30 seconds at a time.
I have a powerful workstation (Windows 10 Pro, AMD Threadripper 3990X, 256GB RAM, GeForce 3090, assets on NVME and SSD drives) and yet working with 4K footage just destroys After Effects.
I am using the latest (as of this post) stable release of AE v22.4.
