3ds max + Corona + Windows = Finally good performance

[maru]

Nothing but a total rewrite or a miracle can fix this.

I don't think a miracle without a rewrite would help.

You never know :)
Autodesk hasn't been known much for miracles but they DO happen :)

Hi guys, do you know any other tips to improve 3dsmax stability and speed with Win10 Pro?

I remember reading something that Windows 10 does when an application crash frequently, and it try to solve the problem running the app in a sort of compatibility mode the next time you open it.

I recently built a new workstation and I want to optimize it as much as possible :)

That's FTH - thankfully Corona catches it when FTH includes 3ds Max or related processes and warns about it. My suggestion is to always disable it fully. :)

I think it's time for definite "Setting up Windows 10 for (rendering) work" write-up :- ).

It's getting hard to even remember it all, setting it all from ground up after every re-install is pain.
I was huge fan of Windows 10 originally, but it's becoming far too candy-crush optimized.

Thanks Marcin!

I totally agree!
Are you going to write it? :)

Remember the old Windows XP "patchers" that would remove the arrow icon from shortcuts, etc? Maybe we should just ship something similar with Corona installer. :)

It would be really helpful to have some kind of automated setup to make your max/corona/windows environment work better.

The windows defender trick is doing something here, I would have to measure thing up but the placebo effect must be high, material editor, rendering starts are working faster.

I tried setting the windows defender antivirus to disabled in the local group policy editor but didn't notice anything. Do I need to also turn off the windows firewall?
On a side note, after I disabled defender qtwebengineprocess.exe started running in the background and maxed out 128gb of ram. I deleted the 3ds max install folder, which contains qtwebengineprocess.exe, sitting on my desktop and that problem went away. But I think it's unrelated to disabling the defender antivirus.

I would like to add few additional insights, although not specifically related to the "Defender" thing.
Still using one machine here, but noticed considerable decrease in performance and stability after several Windows 10 updates, which occurred around end of March.
It was mostly related to 3ds max instability, frequent freezes which eventually influenced Corona experience.
Made investigation as read a post somewhere that the following windows 10 updates "B4535996, KB4540673 and KB4551762" can cause some serious trouble.
Happened to have had  installed the latter and after removing it - back to normal.

Completely support the idea that we need to organize a windows 10/3ds max file or note where to put most common software related stuff that might be the real culprit behind some of the issues people are experiencing.
I am personally working from a network and almost every single file becomes  quite slow at certain point. Trying to avoid keeping multiple 3ds max instances opened as well, but... avoiding is not a solution. :)
Still using 3ds max 2018.3 but it is bit sluggish in UI, bit slow and more unstable than 3ds max 2018. Tempted to try most recent versions, but really do not want to go down the rabbit hole.

Hello everybody!

I've opened this thread only to share this few basic tips which are a result of two years of problems and recently improved my performance drastically.


[short introduction]

I've just opened an account on this forum just to tell you this important information regarding performance. I've been using Corona as my main work tool since version 1.2. I work as an interior designer and Corona has become my main tool even though I am very skilled in Vray. Over the years I've been having CONSTANT problems with various versions of 3ds max and Corona and of course - windows. Many don't understand how many bugs are produced by bad 3ds max architecture (nothing to do with Corona), and even worse bugs are produced by windows. Like many, i just need things to WORK because my business depends on it. Every one of this tips has been tested and verified over and over and trust me, I have had crazy 12-hour full exterior overnight projects and I really know what I'm talking about.


[technical tips]

-I will start by saying: if you use Corona and 3ds max you absolutely HAVE TO use Windows PRO , not home and lower variants.

-(most important tip)- DISABLE windows defender, DISABLE firewall. Now, I've done this years ago in windows defender and in control panel and it didn't work. It's very important to do this by group policies editor in Windows pro and up and/or via registry editor. Only that way will completely disable it.
Explanation: it solves the most annoying performance hitter which is (LONG) waiting every time you start up 3ds max, close 3ds max, start rendering, stop interactive or regular rendering, loading maps, merging files, etc etc... This will save you so much time its crazy. Windows architecture is set up in a way that somehow has to scan and check all the files that come in through RAM and that is the main reason for slow performance.

-in my experience, 3ds max 2017 and 2018 were the last versions in which i am able to reach peak performance. Later 2019 and 2020 have issues admitted by Autodesk and not yet fixed. The improvements do not outweigh the problems.

-you don't need to use 3ds max as administrator, it gives you problems when merging files.,


These tips finally gave me the perfect experience. No crashes, no waiting, just work. Hope it helps.

For all those who missed this LIFE SAFER topic, I am bumping it...
I tried most of advices here...and now I can go to coffee!
As at least 30-45mins you will get per day, if you work 8-10h
it is hard to calculate ofcourse, but all those waitings are now GONE FOREVER.

It is literally like upgrade from Coppermine PIII to C2D.
when working in 3dsmax, max is responding IMMEDIATELY, almost...!
Thanks everybody for writing in this topic...Cheers!

Could anyone explain more about how to set up the group policy level disabling of windows defender for corona/max?
