In the Menu Bar, select Edit > Preferences, then on the left side of the dialog box, select Render Options, then the Visualization Advanced tab.

Advanced Rendering

Use Wide Gamut Display

Toggles the use of wide gamut display on or off.

Disable Main Thread Sleep

Prevents the computer from sending the main thread to sleep.

Use 10 Bit RGB

Offers better image quality, provided your graphics card supports it.

Cache Geometry

Uses extra main memory (RAM) to try and improve performance.

Force GLFinish

Forces a full syncpoint for the GPUs, after a buffer swap, when rendering is slow, due to background buffers in the GPU driver.

Single Pass Stereo

Improves performance by rendering a pair of stereo images in a single render pass. Check out the Stereo video to see how to set up rendering in stereo.

Occlusion Culling

Disables the rendering of invisible objects. This can improve performance in complex scenes.

Realtime Antialiasing Presets

Uses these setting for the Render Options > Visualization > Render Window > Antialiasing Quality options. Customize settings for all Realtime Antialiasing Quality presets from low to ultra quality settings. Click here to view a rendering Antialiasing video.

Multisampling

Samples ranges from 1x to 16x. If a platform does not support a sampling level, it is silently clamped.

Variable Rate Shading

Sets the shading rate per material, which is useful for materials with fine patterns that are prone to the moiré effect. Choose from 1 Sample (Native shading), 2 Samples, 4 Samples, and 8 Samples (Supersampling).

Enable Pixelfilter

Enables a triangle pixelfilter to use with multisampling. Staircase artifacts caused by standard GPU Box filtering are removed.

Enable Supersampling

Creates a render buffer with 2x the size and is downscaled with a triangle filter. When combined with 16x multisampling, 256 samples are taken.

Raytracing

Displays the number of samples, from 1 to 16, used in the raytracer for realtime antialiasing. Check out the Raytracing videos to see how to set up raytracing.

Background

Sets the background colors of the Render View. The background can be a gradient, with different colors set at specified positions. Use the Add, Delete, and Choose Color buttons to make your list. Define each color using RGB values and with positions ranging from 0 to 1 (bottom to top).

SLI

SLI Mode

Select the SLI mode to distribute rendering across two GPUs.

• Alternate Frame - Sets one GPU to renders all the odd frames and the other the even frames.

• Multicast Stereo - Renders the scene from two different viewpoints, distributing the workload across two GPUs. If you use VRED Design and an OpenVR HMD or Oculus Rift, use this setting.
