Compostion Window Freezing with RTX 5090 / Ryzen 9 9950X
Hi everyone,
I have a brand new high-end setup, and so far, I haven't found any working solution.
My system specs:
After Effects 25.3
Windows 11
Nvidia RTX 5090 (tested with latest studio drivers + older versions)
AMD Ryzen 9 9950X
96GB RAM
The problem:
During very light projects, the preview window randomly freezes after a few minutes.
The rest of the AE interface remains responsive — I can click around, open panels, but the composition preview is stuck.
GPU usage stays around 1%, so it doesn't look like a performance or overload issue.
I have tried the following with no success:
- Switching to older versions of AE
- Switching to "Mercury Software Only" for rendering
- Testing multiple versions of Nvidia Studio drivers
- Clearing cache and resetting preferences
- Disabling Multi-Frame Rendering
- Using a single monitor setup
Interestingly, I had a similar issue with Blender, where the viewport would freeze. I solved that by switching from OpenGL to Vulkan. Unfortunately, After Effects doesn’t seem to allow Vulkan rendering yet.
My suspicion:
This might be related to compatibility issues between After Effects and the new RTX 5090 (Blackwell architecture), but I’d like to hear from others to confirm.
Any suggestions or insights are welcome, thanks in advance!
