How to enable gpu rendering/CUDA in after effects 2020 (trapcode form and plexus)?

Hey Prenx4x,

While I don't think u can render with GPU in AE - you can select "Add to Adobe Media Encoder Queue" in the Composition menu or CTRL+ALT+M to send your comp to Media Encoder and use that to render via CUDA. in Media Encoder you can select what type of Renderer - set it to "Mercury PlaybackEnding GPU Acceleration (CUDA)" I did a test and see a dramatic speed increase rendering via ME vs AE.

If CTRL+ALT+M doesn't work - check your Nvidia shadowplay keybinds... by default there is a conflict with Shadowplay's MUTE MIC keybind which is set to the same hotkey combination.

Plexus only uses OpenGL, so obsessing about CUDA is rather pointless. OpenGL being a limited acceleration architecture in itself you won't see much use nor will it boost performance beyond a low percentage. That's even more the case when you create complex setups that may break the linear rendering or exceed the hardware shader capabilities. The same applies to Form, even if it uses some more acceleration. In any case, none of that will do anything miraculous and the usage percentages you get are therefore all there will ever be, given how AE's render pipeline and data communication works internally. Only infrastructures fully decoupled from these limitations liek e.g. the Trapcode effects builder will ever make the most of powerful hardware, but that's another story entirely.

CUDA drivers were only implemented to support Ray-traced rendering. The general GPU functions support effects that can use this kind of acceleration. Check the settings in the Project Panel for GPU acceleration. That is where you can experiment with the settings. Here's a screenshot from a Mac. The Windows version is similar:
