Ive been having this issue with ArmA, When I start the game everything is blurry as hell and you can't see anything. I bought the game off of steam a couple of months ago and on my other computer it worked fine and I had a blast. But now on this computer it's lagging really hard and the graphics are blurry. It's not a hardware issue because the computer I got can run GTA IV no problem because it's a high performance computer. I really want to play the game I payed for.
Here are some photos of the issue.
