too little noise after image is saved

[glimpse]

Well, it would be dumb to complain, but I'm trying to understand here:

why does my render in max look much more noisier than it looks saved? - here's the same 12% (4k) & 50% (8k) zooms..
If I judge image by the look in OctaneRender window..I would leave too long to cook =)
I can live with the noise as is saved..especially if I'm looking to downscale afterwards.

I though Octane is more or less "What You Is What You Get", but I got surprised today, a bit..
as working side by side in photoshop while rendering noticed huge difference.

Maybe I touched something in panel that I've never used?..or is it normal & I haven't noticed that before?
(filter size is on 1, if matter anything =)

cheers

p.s. I think I start getting it - You can't judge the noise amount if You're not looking 100% - any other scale (half, quarter..whatever) doesn't reproduce real amount of noise.. - So if You're rendering 8k (that's way bigger than the screen =DDD - zoom in..otherwise You probably cook the image too long! Curious why it's only now that I've noticed that =)

i believe is an old trick (maxwell render)... render big and then resize reduce the noise...
max buffer does not interpolate the pixel when is zoomed out like photoshop or image viewers...

yeah, the trick is nothing new.. in unbiased solution.

anyway, the idea of this post is not the trick..
but the representation of calculation on Your screen =)

& I'm just curious..

this noise is for the bump, value 1 means much noise
try to use normal map is better in the cannel normal
