After Effects stuck and unresponsive during RAM preview. (Windows)

[Kekemarc]

I've been having an issue lately where RAM Preview gets stuck in an endless loop while the UI becomes completely unresponsive. After Effects itself doesn't appear to be in a non-responsive crash as I can switch back and forth from it and other applications — it's almost like all user input gets disabled. 

Setting the preview playback to play-once works and AE is still usable - so this is an interim work around for the problem. It has been happening for the last two minor releases of AE and only on my Windows machine. This has not been an issue on my Mac.

All drivers etc are up to date, and I'm fairly certain that the problem did not start after any update to the system.

Anyone else having this issue?

Thanks,

Hi Keke,

I was gonna post exactly the same issue. While doing a ram preview gets stuck and I can't stop it, eventully I have to go to the task manager and stop After affects since I can't get out of the loop and it's completely irresponsive. I'm also on a Windows 10 machne,  AE 2020 and last drivers.

Cheers,

Hey Hugo,

Read a few other posts since my post yesterday. Others have pointed to the Nvidia Studio Driver as the cause of the issue, which is what my system has. Is this what you're running with on yours?

Unfortunately I can't switch to the Game-Ready driver to test it out, as it will probably affect other software that I need.

I wonder if anyone out there (using the latest versions of 2020 and the studio driver) does not have this issue?

Hi Keke,

Yes, I'm using Nvidia studio drivers 2020 and I don't want to test the game ready because I need them for Cinema 4D GPU rendering. Well then, we will have to wait for an update, but very weird bug for a high end compositing software like AE.

Thanks for your help! I'll let you know if I find out anything else.

Cheers!
