Question

After Effects very slow in RAM preview on Windows. On worse specs on Macbook goes smooth as can be.

Dear everyone,

I am making a simple explainer video. Simple in terms of not many effects or other heavy things. Somehow on my Desktop PC with RTX 3070 and AMD Ryzen 9 3900x the RAM Preview often stops after 2 seconds. I tried a lot of things such as:

Purging Cache / Memory
Creating more Memory (I allocated 28GB of 32GB to After Effects)

Making more Disk Space available.

The thing is, I use the same settings in AE and exact same file. Somehow on my Macbook Pro 2022 (with less RAM, and less specs in general) it goes smooth, or probably as one would expect. Something that is a clear difference in terms of numbers is the Render Time that's being shown in the latest version of AE, those render times are a lot higher on the Desktop PC as well... Maybe this could be a hint?

Any idea what I could do? The attached photo is from the Desktop PC. The same frame renders at 46ms on the Macbook Pro 2022.

I am having the same issues.  I am having so many playback issues where I never had before.  I tried everything including deleting preferences.  AE Beta has no issues playing back the same project.

It is frustrating isn't. I am now in the stage I definitly tried everything in terms of "closing other apps, allocating enough memory" but with exactly the same settings the M1 on my Macbook Pro beats the AMD Ryzen 3900x... That doesn't make sense to me. Eventually I bought the desktop hardware to be quicker 😛

You need to fix your graphics and CPU drivers. This happens when hardware acceleration is running in quirks mode and only half works.

Hi Mylenium, I actually have the latest drivers. Even tried some rollbacks. Any other pieces of advice? My Macbook with worse hardware renders consistently quicker and RAM previews a lot faster.
