Stupid question///
How works option /Adaptivity recalculation pass interval///
For what this?
It's works or no?
This for synchronization adaptivity passes on slaves in DR mode?
And if exist problem with dump file /render from file/ and /resume last render/ with DeNoise filter in last Daily Build, what I have previously described in this topic???
I ask because I get stripes on rendering
when I am using Denoise filter and DR mode///

It's there for experienced people to test and help us find a good default. It will be most probably hidden in final release. If you do not know what it is for, then just don't touch it :)

Hmm, looks like the "Adaptivity recalc passes interval" spinner doesn't do anything, it's still using 10, no matter what is set.

yep, doesnt work, will be fixed

it does not work at all, even in others "experienced people" :)

Then I would just report it on mantis. Pavel is really good and fast at fixing his stuff :)

Well, here is a test of 12.03 build where you can see that adaptivity recalc interval does work (in a way). There is no point in discussing this further as this is just a test option, and all the issues related to it are already known.

Hi Maru. On my screen it seems that 500 works best in this case. But small pictures + web compression makes my unsure. So what setting would you say would works best in this particular case?

What maru shows is pretty much extreme case where adaptivity should be disabled. Recalc value of 500 means adaptivity is disabled for initial 500 passes, which is why it looks so good.

If the spinner doesn't work, you can still use the string option "int adaptivity.adaptivityInterval", that one should work for sure.

This test does not have any practical sense. I just wanted to show you that recalc adaptivity does work. It looks like I may be wrong though...

I already fixed it, but it is not released publicly yet, we need to fix some scheduler issues before a next public build

I'm having an interesting issue, where Corona will only use 1-2 cores out of 4 to render.

I can't figure out if it's a bug in the lastest daily or if it's the demo version of GrowFX that fucks everything uP anyone had experience ?

thanks

EDIT: it looks A LOT like it is growFX demo that is causing this limitation.

EDIT2: how ever it also does seem that if I start / stop the render over and over, every so often Corona will use very few resources and take 20x longer to do scene parsing and the secondary calc is all bugged and very lacking.  Takes a long time to force stop it but once you do, if you rerender everything is back to normal and fast.  I have seen this in a daily build before, many months ago.. maybe even a year ago.

Well if GrowFx really is the culprit and this behavior is repeatable across different scenes where it's objects\models are present, then it's indeed some sort of it's demo version limitation because it's full version (which I tested just minutes ago) does not do anything like that.

I have noticed that randomly happening extremely slow scene parsing too, but right now I'm not working in max day to day so I cannot confirm how often that happens or what triggers it. I'm not sure about secondary calc cause I just haven't encountered that or maybe I just haven't noticed something is wrong.

Can you try manually changing process priority of 3dsmax.exe to low in task manager and see if it helps?

I generally always run it with below normal or low, but I will keep an eye out to be sure the next few days.

Disclaimer! This is not meant to turn in a discussion about which temps people think is okay, what they are comfortable with etc etc, all that is pointless!  so don't start it plz.

I'm usually running Open Hardware Monitor as default and due to my large screen space, it's usually also open.  Basically I actually keep an eye out, specially right now since I just got a new cpu cooler.

But today I noticed something very interesting, when I render using all cores in Corona (hit the render button), my temps end up at XX and sits there fairly stable even when rendering for an extended amount of time, but here is where things get odd.  I noticed in OHM that my max temps (so the highest temp a core gets to even if its for a split second) often seems a lot higher than what they are when I monitor it.

It turns out that my cpu jumps about 10-15 degrees in temp only during the denoise stage!   CPU load is 100% both during rendering and denoise, no changes there, but it's like the cpu suddenly gets a lot more voltage when rendering stops and denoise starts?  Could there be something in the way denoiser is written that could cause this?

Since I am overclocking and pushing my computer power, while still being at temperatures that are fine and okay, having temps suddenly jump 15 degrees even for 4-10 seconds feels very scary!  Temps aside, it feels like it could also lead to instability if there really is something going on? 

I just wanted to highlight this find, if anyone else wants to do some testing.   I will try another temp monitoring app as well (though this usually works like a dream).

edit:  p.s. I am using the latest daily 12th of march.
