Hello!

 

Today I'd like to direct your attention to a bug fix that is available in After Effects Beta, v22.4:

  • When you use Microsoft Remote Desktop to log in to a Windows computer, the "Hardware Accelerate Composition, Layer, and Footage" panels option in Preferences > Display is no longer automatically disabled.

 

We know that there are a few folks out there who use Remote Desktop to access the machines where they use in After Effects, or are using virtual machines. In fact, some of our developers are among them!

 

This bug fix addresses the problem where the Hardware Accelerate preference was automatically disabled when you launch After Effects for the first time when using Remote Desktop. It was possible, after you launch AE, to enable this preference and continue working, but once you log out and log into Remote Desktop the preference could automatically disable itself again.

 

A few features in After Effects are dependent on this preference being enabled, like the Draft 3D preview mode in the Composition panel. Having the preference automatically disable itself was a little bit annoying.

 

To fix this, we have simply removed a check for Remote Desktop that was added to After Effects a long time ago, when GPU technology used by both Remote Desktop and After Effects was different and wouldn't support the hardware acceleration feature.

 

What we want to know from you is: do you encounter any problems with using After Effects Beta via Remote Desktop?

 

Truth be told, this fix has actually been in After Effects Beta for about a month, so if you've been using it on Remote Desktop, you've already been testing it. Because this bug fix is rather simple, and use of Remote Desktop is relatively uncommon for After Effects, we wanted to let it bake a little bit. Now that we've done that, we just want to double-check whether anybody has encountered problems before we move this bug fix into the next public release of After Effects.

 

We should mention that this bug fix only addresses the code that was automatically disabling the Hardware Accelerate preference. This fix does not change anything about how After Effects uses the GPU on the remote machine, whether the machine and its GPU are physical or virtual.

 

Thanks much. Cheers!
