AE 2020 won't stop RAM render. Please Help!

[moonspinner5656]

AE on PC Windows 10 Wont stop RAM renders. Space bar does not stop the RAM render as normal. The RAM render continues through the entire timeline, then plays back on a loop. Nothing short of quitting and restarting will stop it. Can't work with it this way. Any suggestions would be appreciated.

1801 Mhz 48 cores

supermicro

128 GB RAM

Windows 10

Thanks

I'm not sure what happen with you but try to set the render to run once

[moonspinner5656]

Thanks for the kind reply. Unfortunately, this is not the issue. Typically when I start a RAM preview it can be stopped - interrupted by hitting the space bar. Now, nothing I do will stop or interrupt the render, so RAM preview basically becomes unusable.

No help, but I'm having the same problem. Usually happens when I've got complex comps with several layers and pre-comps.

[Nicolas Deslé]

I have the exact same problem..

Same problem here, and I am on a MacBook Pro - macOS Catalina 10.15.6

[ChrisDAQ]

Me too: MacBook Pro - macOS Catalina 10.15.7

[Duggs1]

Me too! It's not even when it's a complex comp, it's surely a bug.

Sometimes I can get it to stop with lots of wild clicking and button-mashing but by that point I'm already massively infuriated with it, snapped out of my creative flow and it'll then happen again a minute later and I'll get all sweary and have to go for a walk.

FWIW, rolling back to AE 16 worked for me. HUGE relief. (BUT still hacked off that I can't use the currrent version.)

V16 didnt have this issue and there are several users cmplaining about this on 17.0

I am surw Adobe is looking into this as we speak

Hey Moonspinner,

I was suffering from the same issue since updating to the newest Nvidia Studio driver (443.92).

Uninstalling and reinstalling the driver with a custom install solved the constant RAM Render. 

Hope this solves it for you as well!

Thanks for that - that seems to have done the trick with me with that same new Studio Driver

I have the same problem after updating my Nvidia drivers yesterday. I think it has to do with the message in the viewport that poped up since then Display Acceleration Disabled

Here is a post for this problem but didn't resolve it for me yet. https://community.adobe.com/t5/after-effects/faq-how-to-fix-quot-display-acceleration-disabled-quot-...

In AFX 2019 I get the same message but at least I am able to stop the ram preview

[PFuerst · Accepted solution]

A quick follow up. I went back and installed the former Nvidia Driver from their site https://www.nvidia.de/Download/Find.aspx?lang=de and now the Display Acceleration Disabled is gone from the viewport and I can start and stop ram previews normally. So I guess it is best to not upgrade your graphics driver or downgrade for now until it is fixed

[moonspinner5656]

Thanks to everyone who responded. I think this is a good fix for now until Adobe can make this change.

Had this issue as well. Rolling back to the previous studio drivers worked for me!

[HuntmanC68]

If anyone is currently having this issue on the Razer Blade 15 or any other PC that has either the Studio or Game ready NVidia drivers, I was able to fix this by switching to the Game Ready driver for the time being, not sure exactly why this update of the studio driver effected this, but this worked for me.

I'm having the same issue. The RAM preview wont stop playing no matter what. I found that it dosent happend when After Effects is not in fullscreen mode. Just exit the maximaize window mode and it's working again. Probably a GPU issue, but that worked for me.

[Jammer J]

this issue has cost me a LOT of time.  Angry

[PFuerst]

I've just seen that there is a new Nvidida driver update https://www.nvidia.de/Download/driverResults.aspx/161493/de

has anyone tested it yet? Is the problem still present or is it now solved?

[Coralbh]

I just installed the new NVIDIA driver (Nvidia Studio driver 451.77) and the problem was solved .. it works perfectly

[icecreamofdeath]

Same problem here. Even a comp as simple as two shapes with two position keys each, gets stuck looking the RAM preview, can't stop it without a force close.
