This section describes all of the settings and options available in the user interface of the nDisplay Launcher.

Launcher Tab

Control

Description

Render API

Specifies the rendering API to use the next time you click Run.

Render mode

Specifies the type of output nDisplay produces on every cluster node. 

  • Mono - a single monoscopic rendering of the scene from the point of view of the camera.

  • Frame sequential - active quad buffer stereo.

  • Side-by-side - passive horizontally aligned stereo.

  • Top-bottom - passive vertically aligned stereo.

Mono does not require any specific hardware features, but frame sequential does. Make sure your display device, GPU and diver settings are compatible with the render mode you choose.

Use All Available Cores

Forces each Unreal Engine instance to use all available processors on its host.
When this option is selected, the nDisplay Launcher adds the USEALLAVAILABLECORES option to the command line it uses to launch each instance.

No Texture Streaming

Disables texture streaming for each Unreal instance. Highest quality textures are always loaded.
When this option is selected, the nDisplay Launcher adds the NOTEXTURESTREAMING option to the command line it uses to launch each instance.

Custom command line arguments

If you want the nDisplay Launcher to pass any additional arguments on the command line it uses to launch each Unreal instance, include them here.

For details, see the Command-Line Arguments reference.

Custom ExecCmds

If you want the nDisplay Launcher to pass any console commands for the Unreal Engine to execute at startup, enter them here. The nDisplay Launcher passes these commands to each instance of your Unreal Engine application using the -ExecCmds command-line parameter.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
