@Pharacter already fixed

Change it to dev build, you can check Arma 3's quick start guide on how.

@Unratedmerc thats likely because most people are using the stable build rather than the candidate.

I have minimum requirements for GFX Card (Intel HD Graphics) but everything else have is above reccomended (Intel Core i5-3330 CPU 3.00GHZ, 8GB RAM, etc.)

@SplashAnimal you need to update your drivers, the current Intel HD Drivers are 15.28.12.64.2932

EDIT: Updated them too, no difference

Same thing happening to me. Windows 8 64 Bit. Everything else works fine though.
