There is another issue I've found. The fog is causing non aliased edges on objects in fog:

We had a look at this scene and the white pixels is sunlight that is reflected / refracted on the specular material of the figures. The post effect fog is as the name says just a
post effect, i.e. when Octane renders the scene it doesn't know about the fog. If there would actually be fog in the scene, the sunlight would be a lot more attenuated, but without the fog the sun is really really bright compared to the sky, resulting in those overexposed pixels you see.
You can emulate this behaviour by increasing the turbidity in the daylight environment, but this would of course require a restart of the render and thus isn't a full post effect anymore.
