Okay guys, after raging so much, i finally am able to play again without any problem.
https://www.youtube.com/watch?v=3bfJO4zBGtA This video is what helped me. Especially 1:37 to 2:40. He show you how to change some values. Do not mind if the number in your files are not the same, just replace them with the numbers he said. (make a copy of the file before modification,just in case) i also got back on steam and put -malloc=system again in launching option (right click arma in steam,proprieties,General launching option then type in -malloc=system. I don't know which one fixed it, changing values or Malloc, but one thing sure, i am happy. Good luck! I used to have the problem as soon as i was moving around or driving a car.

There is another way to fix it. Go in your steam. (The app not the folder) Click right on arma3 propieties, launching option and type in ----> -nologs , when you open arma 3 launcher select 32 bits in parameter and you should aswell see the -nologs in command line. seems to have fixed it for me.

Hey friend i may have a fix that didn't work for me but maybe it will work for you.
Go to C-User-Yourusername once you're in that folder type in the bar %APPDATA% Check the bar, you will be in roaming folder, just back to Appdata. In that folder find Arma 3 and A3 Launcher. Change their name to Arma 3 - copy and A3 Launcher - copy. Some people said it fixed their problem. Hope you'll have good result.

Asylum? I'm also trying to find a solution. I tried Changing compatibility of all .exe files in Steam-steamapps-common-arma3 to run in windows 7/8 i also check the box deactivate full sceen optimization, Tried to play in 32 bits. It worked for a week or two and december 27 after christmass i reopened the game (there was an update too...) and it crashed. The problem is back..
