@joeubi, try verifying the integrity of the game cache. This will make sure that the game files are correct and not corrupt.

== "D:\SteamLibrary\steamapps\common\Arma 3\arma3.exe" -name= -malloc=system -nosplash -exThreads=8 -maxMem=16326 -maxVRAM=2047 -cpuCount=4 -enableHT -exThreads=7 -malloc=tbb4malloc_bi -enableHT -mod=

There are discrepancies with the launch parameters.

-name= is not defined. Remove it or define it.

-malloc= is defined twice - -malloc=system and -malloc=tbb4malloc_bi. Remove -malloc=system and kept the default memory allocator - -malloc=tbb4malloc_bi.

-exThreads= is defined twice - -exThreads=8 and -exThreads=7. Either remove -exThreads=8 or remove both.

-maxMem=16326 is not valid for the version of the game that you are using - 1.66.139586. Use a valid number or remove it.

-cpuCount=4 and -enableHT should not be used together. Remove one or both.

-enableHT is defined twice. Remove one or both.

If none of the above solutions resolve the issue then please prepare and attach another troubleshooting report for the developers to review.

I removed all the launch parameters except for the memory allocater. It seems to work much longer, however I still get a crash after a period of time. This time much much longer.

@joeubi, did you also try verifying the integrity of the game cache?

The arma3.rpt files in the new report that you have attached still show a custom memory allocator being used.

== "D:\SteamLibrary\steamapps\common\Arma 3\arma3.exe" -malloc=JEMalloc_bi -mod=

Allocator: D:\SteamLibrary\steamapps\common\Arma 3\dll\JEMalloc_bi.dll

Remove -malloc=JEMalloc_bi and make sure the game uses the default memory allocator.

If the above still does not help then try switching to the profiling branch. Instructions on how to do so are provided in the link. See also Arma 3 STABLE server 1.66 "performance binary" feedback - page 74. After downloading 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

If none of the above helps with the issue then prepare and upload a new troubleshooting report for the developers.

Hello,

Verifying your game cache integrity is the best way to resolve any problem but it doesn´t works in all cases. Many issues are caused by some discrepancies on user computer (viruses, low memory space, many tasks in background, custom memory allocator or corrupted Direct)

Try all solutions mentioned by Jawsh. He´s very kind to help us.

At first, launch Task Manager and cancel all unnecessary tasks in background.
Second, set default memory allocator via Launcher parameters.

or

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

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

or

you can try reinstall your Direct.

Direct manual installation

Let me know if the issue still persist or not.

Thank you for your report.

Sorry it has been resolved. The crash was due to Rivatuner Server

Hello,

I´m glad to hear it.

Enjoy the game.

Bye
