Your post just doesn't make any sence.
That's a Vray feature to overcome irradiance map limitations. It turns on brute-force sampling method for small details.
Octane is totally different render engine and uses Path Tracing. No GI blurring is happening in the 1st place.

Thanks for the answer, I'm no expert in this matter

You're welcome.
Expert or not, but you could at least familiarise yourself with the features you're actually requesting.

Nice job! This look like a very useful feature.
Would this option generally speed up noise clearing in all HDRI cases, or only specific ones, where HDRI is producing lots of fireflies?

All HDRI cases, yes

Am I right to assume that this is best when using only HDRI for lighting and becomes less effective the more lights you add?

@Icelaglace,
Would it cover the lighting situations with mapped HDRI in them, or is it just environment HDRI we're talking about?
Or shoud I not ask more
Cheers,

No, this only applies for environments.

the only one Vray feature that I miss in Octane is the AO used as texture to simulate dirt.
I think it's possible to implement it.
