It's hard to read any text on screen but still possible.
However it's playable. I've got stable 11FPS in busy situations, 35-40FPS at best and drops to 6FPS sometimes.

As useful as I'm sure such a post is, it's not a troubleshooting issue, it's a To the people who are playing ArmA, how is it? (http://www.flashpoint1985.com/cgi-bin/ikonboard311/ikonboard.cgi?act=ST;f=64;t=54633) issue http://forums.bistudio.com/oldsmileys/smile_o.gif
