i fixed this by:

1: right clicking arma3 in steam
2: click properties
3: local files
4: browse local files
5: right click arma3.exe
6: properties
7: compatibility
8: always run as admin

you can also delete your arma 3 app data folder which gave me another 10 minutes or so of game time.

i still crash every 20 minutes though.

BUMP!

yeah, i understand it is alpha so i am not going to get up in arms about it. But it does need to be addressed and fixed. Crashes should be the first priority.
