Since 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, it is important to be able to keep track of the GPU(s) installed in the system. This can be accomplished using the GPUs tab in the main Plugin Options panel.
From the GPUs tab, users can enable or disable the GPUs used as default for main rendering or for the IPRProvides artists a quick preview of the image prior to the final render, and efficiently allows for adjusting some elements in the scene such as lights, shaders and textures interactively. An IPR image contains shading and lighting data including some for visibility, in addition to the software render.. These settings are stored in the plugin preferences file.
Users may also enable or disable the priority settings for each GPU. If the same GPU is being used for both the rendering processe and the display, this means there will be a tradeoff in terms of the responsiveness and performance of the display. It will be useful to enable the priority settings for the GPU to get a better display performance especially while setting up a scene prior to the final rendering.
Render priority
Use this options to set the render priority to be used in the selected GPUs cards while rendering with the IPR or with the main (F9/F10) rendering. If you are rendering with the same GPU used for display, can be useful set the priority for this GPU to medium or low to get better display performance.
Enable all GPUs for F9/F10 rendering
The GPU tab also includes an option to enable all the available GPUs for final rendering (F9/F10) without change the current GPUs configuration.
