0B: Onshape Setup

Performance Tuning

After your initial account setup, Onshape will run a browser check to ensure compatibility. Depending on your browser, additional steps can be taken to improve performance.

Tip

You can test your current performance at the OnShape Compatibility Check Page.

Note

If the browser check fails, you may want to try a different browser. Currently, chromium browsers like Chrome, Edge, Opera, and Arc are the best supported browsers for Onshape, but Firefox usually works with no issues as well. Safari is not well supported.

Improving Chrome Performance

If you are using Chrome, You can try modifying the following settings to improve rendering speeds.

  • First, type chrome://settings/ in your search bar to navigate to chrome settings. Make sure that "Use graphics acceleration when available" is enabled. Relaunch chrome if you have updated it to enable it.
  • Go to chrome://flags/ and enable "Override Software Rendering List":
  • Finally, Try adjusting your ANGLE graphics backend:

Please note that performance will depend on your individual computer setup. We suggest the following process:

  • Choose an ANGLE graphics backend: chrome://flags/#use-angle
  • Click the Relaunch button
  • Check your performance

Repeat these steps for each backend and use whichever is the most performant. Here are some examples all taken from the same machine.

The default configuration
OpenGL
Direct3D 9
Direct3D 11
Direct3D 11 on 12

In the above example, Direct3D 11 narrowly beats out OpenGL, but that won't always be the case.
