Those files should be visible with no extra effort. They only appear if you game actually crashed at some point however. The absence of those files means, that it is in fact not the game that is crashing but your graphics card driver.

As I said before, this is a hardware issue and not an issue with the game itself. I'm afraid that your gfx card is indeed faulty.

In that location I see only DayZ.RPT, BattlEye, MPMissionsCache
Could you tell me how to make those necessary files visiable?

Please try uploading the .mdmp and .bidmp files from this file location:

C:\Users\<Name>\AppData\Local\DayZ\

I will have look at those and see if there's anything that could be causing this issue.

Thank you!

Changing versions of driver is what I tried too, but it had no effect. Temperature of the card is OK too, because during the last crash it was 77.
I'm sure that reason of the issue is the game because till the update on 31 December everything was exellent, even on 30 December.
P.S. My issue is very-very similar to this one:

Hey,

like I said before, it seems that the problem doesn't seem to be tied to the game itself. The game will never cause any graphical artefacts on your screen after you exit the program. That is actually a sign of a faulty gfx card, as are BSoDs.

The points made by shogodz89 are sound. Try checking the temperatures your card is operating at, and reinstalling your drivers. There could also be some problems with the latest card drivers so you could also try rolling back to an earlier version to see if that changes anything.

I had the same issue with my dual AMD HD 7850's. I was having massive graphical corruption in the DayZ client and getting unusual crashes. I tried running FurMark to check for any sort of artifacts but it seemed to run fine.

I found out that both my graphics cards were on their way out. I was having memory issues with both cards that FurMark did nothing to detect. The only way I knew I was having an issue with the cards was by running a Litecoin miner. It was reporting a significantly lower hash rate than normal since it is heavily memory dependent. This wasn't a lot of information to go off of but I confirmed my suspicions later when I started producing a lot of hardware errors in the Scrypt based mining program. Although FurMark ran and looked fine, it apparently did not stress my GPU's to the point where the issue came up. This also never showed up in any game I tested (BioShock Infinite and Boarderlands 2).

I bought a brand new R9 280X to replace the 7850's and the issue never came up again.

I'm not suggesting you replace your video cards immediately. Try uninstalling your drivers completely and the reinstalling them. Also monitor your temps to make sure your GPU isn't experiencing some sort of temperature issue.
However be aware that programs like FurMark and Kombustor might not always show these kinds of hardware issues.

Truly,"Verify integrity of game cache" is what I tried at first when the game started to crash and it didn't improve the problem.
Speaking about my graphic card I'm sure that everyting is OK with it because in other games and stress-tests such as MSI Kombustor there're no any problems.
P.S. Sometimes game crashes cause a blue screen with error "nvlddmkm.sys"

Hello,

please try verifying the integrity of the game cache.

1. Right-click DayZ in the Steam library
2. Click properties
3. Switch to the local files tab
4. Click "Verify integrity of game cache"

If the problem persists, please let us know.

In this case, however, it seems that the problem is not with the game itself. If the artefacts stay on your screen after you exit the game, it might be a sign of a faulty graphics card.

Yes, I'm still able to reproduce it in the latest version.
P.S. DxDiag and other necessary files are uploaded.

Please let us know in note section if you are still able to reproduce this issue in latest Development build.

If so, please send us dxdiag and files from this folder: "C:\Users\<Name>\AppData\Local\DayZ\"

Can you pack the files in winrar and upload it somewhere?
When the *.rar will be smaller than 5.000KB, you can attach it here.
