@Sgt.Smile, please attach the file (drag and drop) rather than pasting a wall of text.

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.

Hello Sgt.Smile,
it seems that you're graphic card has a trouble rendering the program window. Please try to start Launcher in the safe mode and disable the hardware acceleration:

@Sgt.Smile, try the below possible solutions one-by-one:


== "D:\A.Steam Spiele\steamapps\common\Arma 3\arma3.exe" -noSplash -high -nologs -exThreads=7 -maxMem=21000 -cpuCount=4 -noPause -mod=

Try resetting the launch parameters to their default state via the Arma 3 Launcher. Also check under Steam → Arma 3 → Properties → General → Set Launch Options...

Alternatively, remove -high as it is not a valid launch parameter. Remove -nologs so that errors may be logged. Adjust the -maxMem= parameter as described here.

-maxMem=<number>Overrides memory allocation limit to a certain amount (in megabytes).
1024 MiB is a hard-coded minimum (anything lower falls back to 1024). The maximum is influenced by your operating system (any value over the maximum will be reverted to this value):
32-bit Windows + 32-bit game: 2047
64-bit Windows + 32-bit game: 3071
64-bit Windows + 64-bit game: (physical memory*4)/5
Without the -maxMem parameter the engine attempts to set this parameter internaly to a reasonable value often defaulting to max values as described above.
The file cache is always excluded from the virtual address limit, see our developers blog:
Note that setting maxMem to 2000 does not mean that the game will never allocate more then 2000 MiB. It says that the game will do everything in its power to not cross this limit.
In general, it makes sense not using this parameter at all and only resort to it in case you experience issues with memory.


Exception code: C0000005 ACCESS_VIOLATION at 65636375

Try all of the possible solutions listed for 0xC0000005 - ACCESS_VIOLATION on the Arma 3 Unusual process exit article on the Bohemia Interactive Community Wiki.

If the issue persists after trying all of the above possible solutions then use the Arma 3 Launcher to prepare a new troubleshooting report and then upload the report to the feedback tracker for the developers to review.

Type: Public
Build: Stable

Updating to the latest version of Arma 3 may help too.

-malloc tbb4
-maxvram 2048 or higher based on your vga
-cpucount= based on your cpu
