[1.67 DEV] Server CTD when dynamic simulation is enabled
Reviewed, NormalPublic


Yet another A3 server crash related to dynamic simulation

If I disable dynamic simulation completely in the same mission the server does not crash anymore.

A3 version used: 1.67.139899

I've reported quite a few CTDs now and all are related to dynamic simulation (already when it was available in the 1.66 RC).

Try the below possible solutions one-by-one:

Try restarting your computer and then verifying the integrity of the game cache for Arma 3.

  1. Restart your computer and launch Steam
  2. From the Library section, right-click on the game and select Properties from the menu.
  3. Select the Local files tab and click the Verify integrity of game cache... button.
  4. Steam will verify the game's files - this process may take several minutes.

Try all of the possible solutions listed on the Arma 3 Unusual process exit article on the Bohemia Interactive Community Wiki.

Try switching to and playing on the profiling game branch. After downloading new data verify the integrity of the game cache.

• profiling branch (special performance + profiling build - requires access code: CautionSpecialProfilingAndTestingBranchArma3), alternative download of needed binary possible from Dwarden's dropbox

Next, you could try to use this solution, called Change your game profile.

  1. Go to C:\Users\*username*\Documents\Arma 3
  2. Copy all files
  3. Delete the whole folder
  4. Return back your profile settings
  5. Launch the game

Next, solution is based on change video memory limit by these steps:

  • wrong updated GPU drivers
  • low space in your video memory
  • custom graphic settings (high graphic game quality vs. your GPU)
  • discrepancies in the newest release GPU drivers

So, there is some solutions.

  • try to decrease your graphic quality (if you're using ultra set high or medium). It´s possible that your have no more space on your GPU.
  • reinstall your GPU drivers

You can try the last possible solution called All in One Runtimes tool.

  1. Download All in One Runtimes
  2. Tool will repair your Visual C++, Java SE, Adobe Flash Player, Adobe Shockwave Player, Silverlight, DirectX
  3. Restart computer
  4. Uninstall the tool
  5. Launch the game

Let me know if the issue still persist.

Seriously, that was now the last time that I report a bug or a crash.

I'm really tired of it. The game crashes in MP as soon as dynamic simulation is enabled and that happens since it was first available in 1.66 RC in November last year. And all you can write is that I have to verify my game cache? Are you kidding me?

Btw, I'm not the only one, somebody I do not know wrote the same today in BIF in General Discussion for the dev version.
