CPU: Core 2 Duo 2.33 GHz
Video mem: 1GB
Okay, before i change my OS to Win 7, (XP) ArmA 2 runs faster on High setting.
Now i set everything to medium, lower the view distance, vid mem High (in Very high i'm getting a lot of stutters instead)
and now i got a pretty smooth preformance, of around 20 - 28 sometimes 30 +. so thanks for your help everyone
