My Octane render preview is fast. With a medium complex model which is using transparent surfaces, I can snap anywhere in the timeline and regardless and get a 1.5 image with about 50 samples.
Not so when I go to do an actual render with the same settings. Very slow.
I was thinking that this might be due to mesh compilation, but the same compilation occurs in Preview Renders, yes?
How can I emulate the speed of the Preview Render in an actual animation? Frames without Denoiser about 6 seconds. With Denoiser about 14 seconds.
I must be missing something obvious.........
Thank you for the help.

number of samples for both preview and render? Yes, or even fewer for the Render. 20 for Animation Render ( to test denoise) and 50 for PreviewRender .
modifiers in the scene (especially Subdivision) [set to the same subdivision level for both preview and render. Preview Render about 1.5 sec. Animation Render about 12 sec. /frame.
denoising - disabling denoising is helping. Now about 3.5 seconds for Animation Render.
render passes? Not using.
Is the render resolution the same of the one used in the preview? - 1280x720 for the Animation Render. For the Preview, I do not see where to set the resolution. I simply stretch the
window to where I want it. Stretching it full screen seemed to not bother the Preview.
Also, I do not see where to specify denoise in the Preview. With camera selected, disabling it does effect the Preview.
I thought denoiseing was intended, among other things, to increase Render speed due to the lower sample requirement. Am I wrong on that?
Thank you for your help,
