Hi,

It seem that you have allowed parameter related to 32bit and 64bit in same time.

-maxMem=4096 -maxVRAM=2047 -cpuCount=4 -exThreads=7 -malloc=tbb4malloc_bi -maxmem=8193 -maxvram=2049

Try to unload all there parameters or just one group. Depends on which Arma version do you play? (32/64) Also you can try different memory allocator.

There is some fault in RPT related to ntdll.dll so try follow this link.

Also, you can try follow these common possible solutions:

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

Try to delete your profile folder (create a backup) a try to start the game.

The file yourprofilename.vars.Arma3Profile must be deleted.
Path: C:\Users\*username*\Documents\Arma 3

So, there is some next 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

Ok so I tried everything but nothing of that worked.

Every time i got the C00000096 error.
The longest time i was able to play was about an hour.

Try to reinstall your GPU because. Only drivers from many processes can work directly with the core. Another solution is re-install the Arma 3.
