Why Is My SketchUp Running So Slow?

Do you find yourself getting frustrated with the slow performance of SketchUp? Don’t worry, you’re not alone.

Many users experience this issue, and there are several reasons why your SketchUp might be running slow. In this article, we will explore some common causes and provide solutions to help you optimize the performance of your SketchUp software.

1. Complex Models

If you are working on a complex model with a large number of components, it can significantly impact SketchUp’s performance. The software has to render each component individually, which can slow down your workflow. To improve performance in such cases, consider breaking down your model into smaller components or groups.


  • Component Optimization: Use components efficiently to reduce the number of individual entities in your model.
  • Purge Unused: Regularly use the ‘Purge Unused’ feature to remove any unnecessary components or materials from your model.
  • Hide Unnecessary Geometry: Hide elements that are not currently in use to reduce the workload on SketchUp.

2. Outdated Hardware

If you are using an older computer or have outdated hardware specifications, it can negatively impact SketchUp’s performance. Ensure that your computer meets the minimum system requirements recommended by SketchUp for optimal performance.


  • Upgrade Your Hardware: Consider upgrading your computer’s RAM, graphics card, or processor if they do not meet the recommended specifications.
  • Clean Your System: Regularly clean up temporary files and optimize your computer’s performance using tools like disk cleanup and defragmentation.

3. Graphics Card Issues

SketchUp heavily relies on your computer’s graphics card to render models efficiently. If you are experiencing slow performance, it could be due to issues with your graphics card driver or settings.


  • Update Graphics Card Driver: Visit the manufacturer’s website and download the latest driver for your graphics card.
  • Adjust OpenGL Settings: In SketchUp, navigate to ‘Window’ > ‘Preferences’ > ‘OpenGL’ and experiment with different settings to find the best performance for your system.

4. Excessive Plugins and Extensions

While plugins and extensions can enhance SketchUp’s functionality, having too many can significantly slow down the software. Some plugins may also conflict with each other or cause instability.


  • Remove Unnecessary Plugins: Evaluate which plugins you actually use and uninstall any that are not essential.
  • Disable Extensions: Temporarily disable extensions that you are not currently using to see if it improves performance.

5. Insufficient System Resources

If your computer is running multiple resource-intensive applications simultaneously, it can affect SketchUp’s performance. Lack of available system resources like RAM can lead to slower performance.


  • Close Unnecessary Programs: Close any unnecessary programs running in the background to free up system resources for SketchUp.
  • Increase System RAM: If possible, consider upgrading your computer’s RAM to improve overall performance.

By following these tips, you can significantly improve the performance of SketchUp and enjoy a smoother modeling experience. Remember to regularly optimize your models and keep your computer’s hardware and software up to date for the best results.
