Even in offline mode. I have turned off AA, and AS, followed all tips and hints by Skuzzy, and Waffle. I've turned off other players skins, all graphic effects, set the max texture size down to 128, even deleted all sound packs. I've even run CCleaner, and defragged the HD, and still getting close (1.5km-0m) to other aircraft I get a 1-4 second freeze every now and again.
I know my CPU isn't the greatest
