The problems experienced are apparently not frequent enough to attract the attention of the corona team. They haven't said anything about a solution yet. Actually, it could be like this. I think they are waiting for us to diagnose them in order to offer a treatment. Someone should come out and try different environments. Find the problem clearly. They say we will see the solution in six months. Dear corona team, we expect urgent solutions from you regarding the problems. If we are writing in the wrong place, someone should come out and tell us. Let them ask us what you are asking us to do on the forum. The systems where the problems are are known. It should not be our job to install similar machines to the machines experiencing the problem and try them with different versions. Whoever is responsible for finding and solving the problem should step forward. Yes, there are people in the forum who value and care about us. I thank them. But someone should diagnose the problem now. If the problem is the CPU, let's burn it and buy a new one before the warranty runs out. If the problem is the operating system, let's change it. If the problem is with corona, let's go back to the old days before it's too late. I have lost 15 days for this problem. Days when I struggle to see if my machine is broken. In the meantime, if there is someone working on the problem, let them come out and tell me.  Don't let your eyes blink in the dark. Let us know that you are cared for.

What exactly makes you think so? We received multiple support tickets about this problem. The common denominator for now is the CPU model (9950X), although we have a similar report from a 3970X.

We would like to find out with which exact Corona version the problems started. If you would like, please try installing daily builds one by one and let us know which ones works fine and in which one the problem appears. Alternatively, please send us a ticket and we will arrange a Team Viewer session with you.

I was on a Team Viewer session with Skogskalle, but unfortunately I wasn't able to find a solution or even tell what exactly is happening. The problem was freezing happening a few seconds after starting production rendering (total system freeze, can't move windows, etc, it would even kick me out of Team Viewer).
I have one important finding though: the same kind of freeze happened with various V12 versions (including daily builds) and even Corona 11 Hotfix 2. So it appears this is not Corona version-dependent, or at least not something that happened in Corona 12 U1 HF1 or Corona 12 in general.

It might be, though it's just a guess, related to the Windows 24H2 update. There are lots of user reports online about all sorts of performance issues after updating.

I confirm, several more PCs were assembled on the 9950 base, and the problem is not observed on them with 23H2.

The problem appeared in versions newer than Windows 11 Pro 24H2 26100.1742

p.s Unfortunately, there is currently no way to reinstall 23h2 on other PCs to 100% confirm the absence of the problem.

Thank you Marcin for your time and trying to fix the problem today!

For you others with this problem - do you use Bitdefender for antivirus?  And is it by any chance provided remotely using some sort of "managed antivirus solution".  The next thing for me to check is to disable my managed antivirus and see if it makes a difference. (but since its handled remotely I dont know how to shut it down locally - will try tomorrow...)  I know some people have been having problems with bitdefender slowing down certain programs. Havent read of any problems with corona though and have been using bitdefender on my old computer without problems so its a longshot, but maybe you could try and see if It makes a difference?

Or maybe its 24h2 causing it after all. Like Quest I havent found a way to install 23h2 to check.

Taking my message point by point has taken the topic out of context. I just think I have the right to reproach. Should I not reproach?

Since we have gone beyond the solution-oriented conversation, let me say a few things.

I opened this issue in the forum. I did not buy a ticket regarding this issue. Because this forum is directly the ticket itself. It's customer service. It is public relations. If not, warn me at some point and I would be grateful to you.

And yes. When I saw the messages about the problem and the things you asked, I thought you were not taking the issue seriously. There are people who write clearly about their system and problem. Simulate systems. Don't ask us for our watches. Do old new installations and find the problem. This is the job of the corona team. We have to wait for the March update. If the problem is not solved, we will wait another six months. I solved the problem by closing the "EXPO". What about those who can't figure it out?

There is a saying in our country. If you blink in the dark, I can't see it. Are you really interested in us? Are tickets, teamviewer connections etc. available? We don't know this. "We are just waiting in this forum." We do not know if the problem is a general problem. We don't know if it's just us. The problem is either very small, very few people are affected, or no one cares. "There is no solution, there is no need to talk"... It's amazing.

I asked you to tell us what we should do. You shared a few suggestions. Translation error I guess. Don't tell me what to do until you find the solution. Do you really want me to waste my systems and resources on you? Is this software open source? If you want to see what the older version answers, get an x9950 machine. Install old version. Install new version. Look for the differences. Diagnose the problem. And help us plug the problem for now. We will come out of quarantine when we find the vaccine for corona.

Finally, we are waiting for your answer regarding the solution or process. Do not criticize our comments. We are also trying to solve the problem. Don't you realize?

"Please share what stage you are at and what you are doing." So we can understand that there are people who are really working. It's been two and a half months since the issue was opened. Communication remains weak.

I would like to thank the clients and the corona team who tried to find a solution. Especially to you @maru. The Corona team is not 3 people, but you are the person we see the most.

Sure, let's try to understand what is going on and hopefully find a solution together.

Just one note:
I opened this issue in the forum. I did not buy a ticket regarding this issue.
In case there is some misunderstanding here, you don't have to buy anything. You can simply go here and submit a support ticket: https://support.chaos.com/hc/en-us/requests/new
This guarantees that you will be assisted as quickly as possible by our support team.

Thank you for your kind words and sorry if my message sounded unthoughtful or disrespectful.

Update:I have created support tickets for everyone from this forum thread. For now, I am only asking basic questions to collect information. Please respond to my message.

So - part of my problem was caused by Bitdefender antivirus. After uninstalling it I can actually render without freezing, and working in other programs at the same time works as well!  I dont know yet if it renders as fast as it should, but at least it renders.

However - the freezing is still there when using interactive render. It seems to work for a little while but then gets more and more frozen to the point where adjusting anything in the scene is impossible.

The problem is also still there in corona benchmark - it doesnt freeze like the interactive render but it stutters (like 1 second freezes) which affects the score.  Getting varying and too low scores. Ran it 3 times today and got from 11500000 to 13500000. All too low for this cpu.

Not a solution to the original problem in this thread , but if your normal renders freeze and you use Bitdefender - try uninstalling it.

Hello there,

Good and bad news :

Good one : disabling EXPO did solved the lag problem, al least for this first hour testing.

Bad news : my ram is now working at 4800 instead of 6000...

Slower, but not freezing, the overall is a good news !


Next step is to go back in BIOS, set manually the latencies, and check again... I'll try to find time for that today.


Best regards.

I've found this article: https://arstechnica.com/gadgets/2024/08/amd-explains-promises-partial-fixes-for-ryzen-9000-performance-problems/
Here are the highlights, maybe they would be worth trying:

- update your chipset driver
- update your BIOS
- disable core parking - https://learn.microsoft.com/en-us/answers/questions/1524213/remove-parked-status-of-cpu
- disable core isolation and virtual machine platform - https://www.makeuseof.com/windows-disable-two-virtualizations-game-performance-boose/
- go to BIOS and set CPU SoC voltage from the default 1.25V to 1.2V and Infinity Fabric (FCLK) to 2000 MHz
- change your power plan in Windows (try all available options, power saving, high performance, etc)

Corona not alone with such a problem, and seems the fix is the same rollback to 23h2
So its clear now the problem not directly in corona at all, tnx Microsoft ones again.....

Thank you Maru!

Havent tried all of the suggestions yet, but disabling core parking made a huge difference here.  I have to run more tests, but I think I could both render and use interactive render without much problems after that!  Then I reinstalled Bitdefender and now Im having problems with the interactive renderer again... but im guessing thats a problem they have to solve and nothing you can do much about. Normal rendering seems to work fine even with bitdefender installed now.

the "disable core isolation" option made everything worse here so not using that.

Perhaps you could add 3dsmax.exe as an exception to your antivirus?
It's really interesting to hear about disabling core parking bringing some improvement. It would be great if other users could try it and share their outcomes.
