Hi, Aoktar, please answer these questions

1. What is Ms/sec
2. Why not from what happens his drop in one scene from (avarage) 16 to (avarage) 0.7.
Thanks

This all happens within one scene, from one angle, such a sharp drop happened after I changed the bloom power, values 0.2 literally kills rendering time

Octane 2022.1-XB1-(R3), Cinema 4d r26.107

Millions of samples per second. ie. how fast your gpu is able to render the scene. This number will vary significantly depending on content, render kernels and materials.

Those 2 screenshots do not convey a controlled test. One of those renders has a super bright yellow light on the left, the other one doesn't. That will affect noise and thus render speed.

ps. use the green "film region" instead of the red render region, it is a better guide to your final image.

Thanks for your answer but this problem dissapired when in scene was already this light sourse. It happenes regardless from scene and her complexity. Problem solved after restarting my pc, but this very stranger.

Thanks for answer about ms/sec

Your free VRAM is low. It maybe about it and using RAM(OOC) for renderdata instead of it. You usable VRAM for Octane that seems very low also. Check if you have another apps which uses GPU memory(VRAM).
