Options Dialog Box - 3D Viewport Tab

To display the 3D Viewport tab of the Options dialog box, click Tools > Options, and click 3D Viewport.

Render Device

Automatic Automatically selects the best option detected in your computer for rendering the data into 3D scenes with maximum performance.
CPU Uses only the central processing units (CPUs) within your computer when rendering the data into 3D scenes.
GPU Uses a single or multiple CUDA enabled Nvidia graphics processor units (GPUs) within your computer to accelerate image creation when rendering the data into 3D scenes. Only available if you have a valid Nvidia GPU.
Hybrid Uses all available CPUs and GPUs within your computer to enhance and accelerate graphic output of images when rendering the data into 3D scenes. Only available if you have a valid CUDA enabled Nvidia GPU.

Realtime Options

Auto Pause Pauses realtime raytracing when the application loses focus. When it regains focus, the raytrace picks up from where it left off. This helps to save some of the computer's performance for another program that gains focus.
Image Filtering Reduces the noise of pixels in the rendering.

It turns on a noise reduction technique for the first 50 passes of calculation, then turns it off. At 100 passes, an image filter is applied to completely remove noise.

This option slows the calculation rate of each pass, but speeds up the appearance of a complete image.
Maximum Resolution The resolution (in pixels, width x height) of the 3D Viewport and output snapshots.

Fast Rendering Mode

These options apply only when you select Fast Rendering Mode.

Render Passes The limit of accumulation iterations for the Fast Rendering Mode to stop rendering. This limit is used for rendering in the Viewport and offline renderings at the same time.

Denoiser

Initialize Denoiser Shows the Denoiser functionality in the SOLIDWORKS Visualize interface. Denoiser requires a certain amount of video RAM even if it is not enabled or currently being used. When cleared, the Denoiser functionality is not available and no resources are used by it.
Show Button in Main Toolbar Shows the Denoiser tool in the main toolbar. When cleared, you can control the Denoiser with View > Toggle Denoiser and with the keyboard shortcut D.

Interactivity Acceleration Mode

When in Fast or Accurate mode, the following options are available:

Steady No accelerating technique is used.
Blended Blended causes the scene to automatically switch to Preview mode whenever you do anything – such as moving the camera or model, playing an animation, dragging a material, or clicking the mouse in the Viewport.

When you stop clicking or moving the mouse, the scene blends into the raytrace mode you have selected (Fast or Accurate).
Downscaled Reduces the viewport size during interaction. This option improves interactivity but with lower interactive image quality.

Display Options

World Axes (Preview render mode only.) Shows or hides the world XYZ-axes.
Model Bounding Boxes (Preview render mode only.) Shows or hides bounding boxes around models. A bounding box is the smallest regular shaped box that encloses a 3D object.
Parts Bounding Boxes (Preview render mode only.) Shows or hides bounding boxes around parts in models.
Show Selection Outline Shows or hides the highlight that appears around active selections. The highlight is useful for showing what is currently selected.
Show Camera Icons (Preview render mode only.) Shows or hides icons showing the locations of existing cameras in the scene.
Show Watermark Overlays a watermark on the lower right corner of the viewport and final renders.
