I cant switch back to my GPU

I have a problem, my problem is that i switched to CPU - (Mercury Software Only) because i was facing some render problems, later that day i installed the Trapcode Particular plugin and now i cant seem to switch back to "Mercury GPU Acceleration" .

Some things i tried are - Restarting my After Effects and my laptop, un-installing the Trapcode particular plugin, and trying to switch to mercury GPU acceleration in other projects, to identify if the issue is only in that one project or in all projects, and i cant switch to my GPU in any project.

My system specifications are - AMD Ryzen 5 3500U processor, Radeon Vega 8 Graphics, 8 GB RAM and running on Windows 10.

I am using After Effects 21, i will attach a screen shot of what i mean by "i cannot switch back to mercury GPU acceleration" Any kind of help or suggestion would be appreciated, thank you.

If you are on AE Beat switch off multi core rendering as the older versions of Particular dont use this.

The newer versions do.

So as a fist step install the latest version of Particular.

If this fails you can try this:

Uninstall Particular with Maxon's Uninstaller 

Restart AE and start a new comp with a few basic keyframes

Switch back to GPU rendering

Reinstall the latest version of Particular

I have seen this before where the Particular "flag" default was reading incorreclty 

This fixed it on a Mac (should work on a PC)

Did you try any solution, like restart AE or restart your PC? 

You also check the updater of Trapcode.

Hi Zeeshan,

Sorry for your issue.

As Mylenium mentioned, your system specs (CPU, GPU, RAM, OS) would help us to troubleshoot the issue properly. Also, what's the version of After Effects you're using: https://community.adobe.com/t5/after-effects-discussions/faq-how-to-find-the-exact-version-of-after-effects-you-re-using/td-p/9972137 

Let us know.

Thanks,

We honestly can't know. You have not offered any system information or other details, most critically of course being your GPU info and whether or not it actualyl worked/ works on some level. That said, of course using heavily GPU-accelerated plug-ins like MIR could simply exhaust all hardware resources and prevent AE's own GPU usage from ever doing anything meaningful or even not being available, so the first thing to check is whether this works in a project not using this stuff. That and of course the usual steps liek updating graphics drivers and possibly trashing the prefs.
