Okay so I had Arma 2 and Arma 2 OA a couple days ago to play DayZ/Wasteland and such. I completely wiped my computer because it was getting really laggy on the internet. After i wiped it, i redownloaded Arma 2 and Arma 2 OA but now im getting 1 fps on both arma 2 arma 2 OA and dayz. i dont know the problem and im dying to play the game. Whoever could help i would greatly appreciate it. (no video settings changed) (had around 30 fps before) Thank you:)
