Question

After Effect 2026 playback lagging heavily despite decent PC

Current Spec: 64GB DDR4, NVIDIA GeForce RTX 3060, AMD Ryzen 9 5900X, set my disk cache at 115GB on 3400MB/s read speed, about 5000MB/s write speed, set ram reserved for other app to 6GB, paid application, enable multiframe rendering
Something likes this took me like 1 min to play back, its literally just basic 3d rotation and positioning keyframe, no crazy plugin or effect
Tried switching the codec for the video on another comp but it doesnt help much
I can add some other settings/info if needed

    There is also a 3D cache. you can empty it from Preferences>3D>3D cache

    Did you try purging all cache and memory?

    Sorry to hear about the issue. Are you working with a screen recording? If yes, can you try transcoding it? Screen-recorded media is often recorded with variable frame rate, and After Effects sometimes struggles with it. Transcoding the media will change it to a constant frame rate.

    Let us know how it goes.


    Thanks,

    I've been seeing quite a lot of reports of people with Ryzen  CPUs and Nvidia GPUs reporting similar problems to me. I have a 5950x, 4080 and 128gb RAM and I've found Premiere and AE 25 and 26 slow to the point of being unusable. Resolve, Blender and every other app I use runs perfectly - these are the only two I have problems with. Gone through every troubleshooting and bug fix but the performance is drastically worse than older versions on the same PC.  I'm just wondering if my setup will never work properly now

    Yeah that's normal. AE doesn't like mp4, but beyond that it doesn't really use GPU, and a 20-45 minute render is common on heavier comps.

    My point is its not heavy though, its literally just 2 layers with 3d enabled no effect
