SUMMARY

This article covers the recommended options for identifying why Nuke is not recognizing your machine's graphic card and how to resolve it.

 

MORE INFORMATION

The first thing we would recommend is ensuring your GPU drivers are up to date. If they are, and you are still experiencing issues, then try rolling back to an earlier supported driver version. You can find which GPU drivers are currently supported from the Nuke System Requirements page of our website, or from the release notes of the Nuke version you are using.

If you continue experiencing issues with Nuke not recognizing your graphics card, then it is likely either a previous graphics card has been saved as the GPU device in your preferences file, or the preference has been saved as no GPU device.

In order to ensure Nuke recognizes your latest GPU you will need to edit your preferences file. To do so, please do the following:

1. Navigate to your preference file, where [username] is the active user:

Linux
/home/[username]/.nuke/preferences15.1.nk

Windows
C:\Users\[username]\.nuke\preferences15.1.nk

macOS
/Users/[username]/.nuke/preferences15.1.nk

  
NOTE: For more information about where to find your .nuke directory, please refer to our Q100048: Nuke Directory Locations article.
  
2. Open the preferences file in a text editor.
3. Delete the entire line starting with selectedGPUDeviceName
4. Save the preferences file.
5. Launch Nuke.
