Prototype is slow but file is small

I have a prototype with a lot of connections but overall the file is small (11%).
Although the prototype lags, loads slowly, and triggers the ‘unable to load…’ browser notification.

  • There are no images within the file
  • Most animations are ‘smart animate’

Hi Justin,
If you haven’t already checked our article to troubleshoot the memory usage, please read our tips here:

If this doesn’t help, please try clearing your cache and cookies in your browser, and then try opening your file again.

If you’re using the desktop version, here’s how to clear the desktop app cache on a Mac:

  1. Quit the Figma desktop app
  2. Open and enter the following command: rm -rf "$HOME/Library/Application Support/Figma/"{Desktop,DesktopProfile}
  3. Try opening the desktop app again

On Windows:

  1. Close the Figma desktop app
  2. Open the Start menu, and paste in this, followed by enter: %APPDATA%\Figma
  3. In the window that opens, delete the Desktop and DesktopProfile folders if they exist
  4. Launch the desktop app again

Feel also free to share a screenshot of what you are seeing on your end when you are trying to load the Prototype. Thank you!
