The Devices Settings

OctaneRender is a GPUThe GPU is responsible for displaying graphical elements on a computer display. The GPU plays a key role in the Octane rendering process as the CUDA cores are utilized during the rendering process.-based render engine, and it is important to manage the GPUs in the system that are used for rendering. This is done through the Devices tab. Under this tab, the checkboxes for GPU’s that are not supported are not shown and users can only enable GPU’s with a supported compute model.

This allows the user to see the following:

CUDA Driver — This shows the current CUDA driver and runtime versions.
Active/inactive device(s) — This allows selecting GPUs to use for rendering if more than one GPU is installed. The render priority option can throttle down rendering on one or more GPU’s to improve system responsiveness especially when rendering on a GPU used for the display.
Device Priority — This shows whether the device will use the priority indicated at the Render Viewport’s Render Priority Setting.
Device information — This shows specifications of the current selected device.
Device Memory Usage — This shows the user how the video card memory is allocated based on the current scenes geometry, textures, render target, etc ...
