Version 22.3.0 (build 107). Since this update, performance has slowed unbearably in both playback and rendering. Rendering won't even finish anymore-- it simply freezes whether local to AE or in AME. Memory use is always much higher than it should be, also. This smells of a memory leak-- but it is preventing me from rendering "anything" at the moment. Memory is currently at 75% utilization with nothing being done-- just idle. CPU is also at 75%-- idle. I have 64 gig's ram, and i7 4.2ghz processor. And playback is almost as bad-- essentially AE is not functional with anything other than very bare-bones projects after this update.
Adobe-- is this a problem that is being looked into related to this update?
Are you on macOS or Windows? Also, which GPU is installed on your computer? After Effects's performance is continuously getting better. However, we've seen some performance-related issues in recent releases. Are you using any third-party plug-ins? Also, have you tried resetting the preferences?
