How To Enable GPU Acceleration In After Effects FIX After Effects Not Using GPU To RENDER

GPU acceleration in after effects is important as you are developing amazing and complex animation or graphics. GPU acceleration is a must for editing in After Effects.

In this blog, I will share many ways to enable GPU acceleration in after effects and if your after effects is not using GPU to render your composition or your exports then I will guide you properly.

Step # 1: Enable GPU Acceleration (CUDA)

Go to File -> Project Settings -> Select GPU Acceleration CUDA under the Video rendering and Effects option

Step # 2: RayTracer Supported Cards

Now you need to close your after effects and make sure it is not running in the background. Once you are done, go to your After Effects file directory.

Default Directory Of After Effects

The After Effects default directory:

C:\Program Files\Adobe\Adobe After Effects 2020\Support Files

You can also right-click on the After Effects icon and select Open File Location to navigate to the After Effects default directory.

Find Required File:

Once you are right inside, Search the raytracer_supported_cards.txt file and open it in notepad.

Once you open the raytracer_supported_cards.txt file, you will see a list of supported GPUs that are used and compatible with after effects, and After Effects will read this file to use your GPU. You need to make sure your GPU is in this list, if not you need to add it manually.

Step # 3 Manually Add GPU name in After Effects Raytracer File

Now you need the exact name of your GPU and to find that press Windows Key + R on windows and CMD + R on MAC to open Run Command and type dxdiag.

Read Direct X tool Information

Once you hit enter your DirectX diagnostic tool will be opened and you need to select Display Tab or Render Tab if any and copy the CHIP TYPE of your GPU.

Note: It must be the same as it is shown here, including spaces.

Now go back to the raytracer_supported_cards.txt file and copy and paste the exact same chip type name in your file and make sure you enter your GPU name in sequence.

Step # 4: Save changes to your file

Once you have entered your GPU name inside the file, close and save it.

Facing Issue?

If you are facing any issues while saving the file, save the modified file on the desktop and replace the existing file in the After Effects directory.


That's it, now your GPU has been added to the list of supported GPUs, and now After Effects will use your GPU to render faster like never before.
