# Viewport graphics configuration

Added in version 3.11.1.

How to open the configuration dialog:

Select the Configure Graphics… command from the viewport context menu.

Changes you make in this dialog will immediately take effect in all viewport windows of the application.

## Real-time rendering method

This option selects the graphics backend for rendering the interactive 3d viewports. OVITO currently provides two options: the default OpenGL renderer and the VisRTX renderer, which requires NVIDIA hardware with ray-tracing capability.

Note

The VisRTX renderer is included in OVITO Pro for Windows and Linux. OVITO Basic only provides a demo version.

## Settings management

OVITO manages two sets of render settings: one for the interactive viewports and one for final-frame rendering of high-quality output images and movies. The settings in this dialog apply to the interactive viewports only (real-time rendering). You can use the Copy settings… function to copy the current settings to the final-frame render settings and vice versa.

Real-time render settings are shared between all viewport windows and get stored in the application’s configuration file. Final-frame render settings get stored in session state files.

For further information on the parameters of the available real-time viewport renderers, please see the respective documentation pages:
