I watched this video recently where multiple renderers were compared. Octane did relatively well with Global Illumination, but performed relatively poorly in volumetrics and all-around render times.

This brings up a point I've had for a while: volumetrics has been an unusable feature for me with Octane because of how slow it is. Are there any suggestions on how to improve the render speed starting from the default settings?
Thank you!
