AE slows to a crawl after 15 minutes of working in it

Hi,

Having really major weird problems with AE. I work with mapping, and have perhaps 200 vertices that I move around the map for frontline movements.

If I don't close down AE and restart it every 15-30 minutes, I am basically wasting huge amounts of time just waiting for it to process moving vertices around. My mouse clicks take 2-3 seconds to register. If I move the mouse while it tries to register it, the vertice gets misplaced. So it becomes a complete torture.

My projects use x2 Photoshop PSD documents that are basically images with some layers imported from PS as PSDs to AE. In total projects have 5 6 layers on average.

What is wrong with AE? After I restart the app, it works normally and fast, for hence some time, and then it is back to a crawl.

I have just bought a PC upgrade to help in working with AE, and it seems like a waste of money now too. Because AE just seems to ruin itself anyway.

I have 64G RAM (had 96G before but bit slower RAM; but so more RAM did not help it in any obvious ways), 7950X3D CPU, 4070 Ti GPU. Windows 11. Pretty much using the default AE install settings. So 10% of RAM and CPU is reserved for other apps. I do not use any plugins.

AE just crashed after 2:30 hours of exporting a video, but that is another story. AE is also riddled with bugs and crashes, which older versions did not have... I really should have stayed on my old cracked AE version and not pay 70 EUR monthly for the Adobe pack... quite disappointed. Had 1% of problems in the older version.

Thanks,
