Reading the troubleshooting forums just makes me chuckle. I can't believe that peopel are whining and complaining about this game's visual and performance when their own hardware is absolute crap.
I am not making fun of those people with older hardware. But to accuse a well-made game like ArmA suck because your old Radeon 9200, 9600, 9700, X800 or 6600, 5200, GF3&4 or a low end 72xx series cannot handle the game deserves a slap on the face. Its time to wake up, you are not going to be able to max out the details of this game or ANY new games with old hardware. Do not blame on the publisher, or the hardware, it just means the time has come for you to ugrade and keep up with the loop!
