My game starts fine but it seems the resolution is saying 600x800 but it can go bigger. It also doesn't allow me to change the 600x800 plus I cant click with my mouse in the game I have to use arrow keys, Space Bar, and enter. I tried restarting and checking integrity in steam and everything is fine it says. Also the only time I get one of the common error codes , as of late, is when I spam click while its first loading with the arma3 logo.
