In the Menu Bar, select Edit > Preferences, then on the left side of the dialog box, select Render Options, then the Visualization Advanced tab.
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.
Occlusion Culling - Disables the rendering of invisible objects. This can improve performance in complex scenes.
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 High.
Multisampling - Samples ranges from 1x to 16x. If a platform does not support a sampling level, it is silently clamped.
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.
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 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.
