[ Update 2.0 ] - Random Crashes [ Interal Kraken decompression error? ]

[Nicopat]

Hello everyone and a good day,


I posted it into the german forums as well but doesnt hurt to post it here too, I think.

Most of you know the new Update 2.0 launched for Cyberpunk 2077 to be prepared for the upcoming DLC/Addon.
So the game updadet to the Update 2.0 and I launched the game.

Everything seemed fine at the beginning.

Really quick I noticed, that my game was crashing randomly. The first crashes happened even during the Benchmark-Test - I tested some setting here and there. Every 2nd Benchmark was crashing I would say.

A little window popped up and told me something about "corrupted files and scripts arent working".


THE THINGS I TESTED TO FIX THE PROBLEM


- I updated my Nvidia Drivers 537.42 [ NO FIX ]
- I updated my Nvidia Drivers to an older version [ NO FIX ]
- I checked my Windows for updates [NO FIX ]

- I ran the game as an admin [NO FIX ]

- I reinstalled the game ( Epic Launcher ) [ NO FIX ]
- I did a "clean install" with deleting all the files ( Game, Userfiles, etc. ) [ NO FIX ]

- I downloaded and installed the game on steam with a "clean install" [ NO FIX ]

- I set up the BIOS on default [ NO FIX ]

- I lowered the graphics [ NO FIX ]
- I disabled DLSS and/or RTX [ NO FIX ]
- I disabled Cloud-Saves and Overlays [ NO FIX ]

- I launched the game in "vanilla mode" with no addons or plugins [ NO FIX ]


PC SETUP / SPECS

- Intel i9 13900k
- Nvidia RTX 3080
- 32 GB DDR5
- SSD/M2


ADDITIONAL AND MAYBE IMPORTANT INFO?

You can see that I tested pretty much everything to find a solution to the problem. Once the game crashes I sent the bug to the team, of course.
When you check

** %user%/AppData/Local/REDEngine/ReportQueue

you can see folders which start to pop up once your game crash. In the folder you find a .txt file which is named [ stacktrace.txt ].
I believe this gives additional information about the reason of the crash ... I think.

I added a screenshot of the folders where you can count 6 crashes today.

If I open the file you see the following :


Error reason: Assert
Expression: false
Message: Interal Kraken decompression error, code: 0
File: E:\R6.Release\dev\src\common\redCompression\src\wrapperKraken.cpp(346)


Iam not sure what kind of file this is but if I check my Harddrive E:/ ... there isnt anything called like this.
I even checked the Cyberpunk folder, if something similiar is there but couldnt find anything.

Is there a chance that the game wants to open or write something into the file above ( wrapperKranken.cpp(346)?
But when the game tries this exactly it cant be found and crashes during the process.


Maybe this is something that might help for some people.
Like I said earlier ... the crashes are totally random and doesnt make any sense at all.


I hope this information helps to find a solution.


Cheers,
Nicolai

I had the same error on my System (13900K).

It was a stability issue. I checked my system with OCCT with “LinPack” and detected the problem:

"Interal Kraken decompression error, code: 0": That was a weak core (Core #0). I set the max ratio to 53. Additional voltage not solving the problem. More than Ratio 53 on Core #0 is not possible. On your system it can be a other Core with other Ratio. Before i know that, i disabled HyperThreading - This works also, but this is not the problem. It looks like there are several 13900K with this problem.

 

[johnnyga001]

Facing the exact same error. My CPU is 13700KF

 

[Nicopat]

Thanks for the information so far ... I will test it while disabling HT. But it will be interesting what the destination of that file means exactly tho.

 

[SchizoBits]

The destination file name is a information for the developers to know where the error occurs. Not a real stored file on your system...

 

[Nicopat]

Disabling Hyper-Threadding worked for a while but after around 1 hour the crash happened again ( same error ).
But it was a good hint!

 

[SchizoBits]

As i mentioned earlier, you must detect wich core are making this problem - I found it out with OCCT. On my 13900K it was Core #0 (with activated Hyper Threading) and limit the ratio to the max value (on my it was 53). On the Asus Z790-E this setting is under Ai Tweaker/Specific Performance Core. You can also try to disable cores in task manager to detect which core the problem is.

I would also recommend sending a ticket to CDPR support so they can investigate:

So far I didn't have issues like that, so I can't say much about it.

 

[Nicopat]

Okay, I will fill out a ticket soon to help the team to investigate. Good call.
In addition I try changing the ratio. Thanks again for your help too.

A little update :

- Reactivated Hyperthreading
- Deactivated Turbo-Boost ( Intel CPU, 13900k )

I was able to play without any crash today and installed OCCT to check the cores. While Turbo-Boost was active,
2 Cores got really warm or lets say ... hot. The temperatures were really high on the CPU while boosted.

But I think thats normal.

So before I manually changed the value of a core I thought to deactive the Turbo-Boost. The program showed me
that not a single core got even close to be hot.

- With Turbo Boost : Average temperature around 80-90°C of all cores ( highest even showed 100°C )
- Without Turbo Boost : Average temperature around 40-50°C of all cores ( highest got around 52°C )

The above temperatures were shown by OCCT while playing Cyberpunk ( 5120x1440, High settings, RTX on )

Iam not sure how accuraty the program is in general but its something to work with.

-----

So maybe the frequency while Turbo-Boost is active, or the temperatures of some cores are making problems.
Maybe thats something to work with.

But thanks again for the communication, ideas and help.

 

[SchizoBits]

Thank you for the Feedback - Glad to hear that is working now!

Sure, if you disable Turbo Boost the max core ratio is also lower. On my system i wanted exactly now, where the problem occurs. And the result was as you know Core #0 with a max ratio of 53. With this setting i get the minimum performance loss and i know exactly where the problem is.

Could be that the temperature plays a role. On my 13900K it was only Core #0. The other cores has no problems at all.

 

[Nicopat]

Of course I will monitor the situation, if the game still crashes. Iam aware, that the 13900k ( or 13th gen? ) can get really warm / hot and maybe thats the issue somehow between Cyberpunk ( software ) and the CPU ( hardware ).

But in general I did the same like you, where I only lowered the power of every CPU. I didnt feel any impact on the FPS at all.

 

[SchizoBits]

The 13900K has 8 P-Cores and 16 E-Cores. By disabling Turbo Boost the entire cores are affected. I adjusted only 1 P-Core.

The temperature could be a problem on this one core. On tests with OCCT i can produce errors on this one core, if i test it with extreme conditions / settings. It is not only a problem with Cyberpunk.

It looks like some of the 13900K's (or perhaps 13th Gen) cores are not good enough for the highest officially frequencies (probably production related).

THANK U GUYS SO MUCH!!!!
13900KF with same problem.
I tried everything and almost give up, until I disable Turbo Boost.
This problem haunted me since I brought this game. It appears random crash on 1.7version but I managed beat this game by crash and reboot almost hundreds times. I tried write ticket but its useless. Reinstalled 4 times, 115 hours on steam but 87.5 hours on my saving. THATS TOURTURE !!!!!
Now I can finally "play" this game.
