Some factors that can introduce a lot of noise are:
- lots of light sources. The more light sources in the scene, the more noise in their illumination.
- lots of glossy surfaces in the scene.
- reflectance values in the scene too high. Octane defaults to 0.90, which is very high. A realistic value of white paint is about 0.60 to 0.80.
- environment light coming in through small windows. In this case use portals to improve the efficiency of the renderer.
Can you give some details of how the light sources in this scene are set up?
For scenes with complicated lighting PMC can give better quality for the same render time.

Thank you for your reply.
I realize there are a lot of things wrong that you said in my scene.
- I have too reflectance in my materials and i don't use portal.
- I've more than 10 light
I'm going to test with portal and i would like to know if the default light setting are good or already very highest ?
