Chaos Corona for 3ds Max > [Max] Tutorials & Guides
3ds max + Corona + Windows = Finally good performance
erisbejbe:
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.

Could you elaborate on your Group Policy settings?
Here is what I do currently:
1) Exploit protection exceptions for 3dsMax & Corona (almost everything OFF, not just Flow Guard)
2) Real-time protection exclusion for 3dsMax & Corona folders (in Program Files, as well as Users&AppData)
I considered this to be a good solution to exclude 3dsMax, but not disable (otherwise excellent) protections. Would love to see some benchmark what further improvements could be done by more drastic measures.
BTW: What's your memory kit ? And what speed is it running stable at 256GB ?

If you have time, write a bit more about this too. There are never enough opinions on how bad 2020 is actually :- ). I am not sarcastic, I am honestly trying to make a more solid picture from all the reports as user of 2016.

I second Juraj's comments. Would like to see some real-world examples of this i.e time to max startup with bitdefender disabled, then firewall disabled vs stock.
I had a quick go at disabling some group policy settings for bitdefender as I'm running avast and no noticable differences were seen...

Please uninstall this shit right now :- ) I am fully serious.
It has no benefit compared to what is in Windows 10, and it's just actively spying on you and selling your data. It's the biggest crap-ware on market.
For those who absolutely need for some obscure reason something 3rd party, NOD by ESET is the only reputable solution.
But actually Windows 10 is more than enough.
