Hello, I have a scene where I have a render time of one frame for roughly 40sec but with Pyro cached sim in it I get 12 minutes :(

So I am wondering what might be the key value in the render settings, I am in Path tracing mode... I have setup of HDRI and few area lights but only one is set up to be visible for that volume thanks to object tag with light ID set.

I guess there must be some value which controll just the volume, like its amounth of noisiness or something...

Any tip would be greatly appreciated :)

Thank you Skientia for your reply, I have already found a solution for me to tweak values of the Octane Volume object itself, specifically the Density and Step Lenght Percent Values were the key here.
