Fast Raytracing Mode Switch

SOLIDWORKS Visualize includes an option on Fast render mode: Speed or Quality. You can access this switch from the Main Toolbar.



  • Fast render mode includes photorealistic features found in Accurate mode, but with the faster raytracing speeds of Fast mode.
  • Fast render mode allows for a greater usage of Fast raytracing mode throughout more and more projects. Accurate raytracing mode is only needed for interior scenes.
Speed: Recommended for fastest interactivity in the Viewport.
  • Speed removes self-shadowing and time-consuming reflections.
  • Speed is ideal for projects without glass, clear plastics, or transparent objects.

Quality: Recommended for final renders.

Set Default Number of Passes for Fast Raytracing Mode

With the Fast mode toggle switch between Speed and Quality, you have the option to set the default number of Render Passes for the Fast render mode. Click Tools > Options > 3D Viewport > Fast Rendering Mode.

Some Fast mode renders can still be noisy. With this setting, you can adjust the default number of Fast mode render passes to reduce any visible noise in final Fast mode renders.

The accumulation process stops once this number is reached. Small values lead to shorter render times but may produce noisy images. The default number is sufficient for most projects.



The Fast mode setting (Speed or Quality) and Render Pass count selected in the Viewport are the settings used during an offline render if you select Fast mode.
