Right, just done a clean re install of my laptop. All drivers updated and its back to the state it was when I first put ARMA2 OA on. Only problem now is I struggle to get past 15 fps lol.
This is the only game causing problems. Witcher 2 works fine, EVE works with no problems. Just ARMA and its driving me mental!

Finally sorted it.
Changed every setting one by one and it turns out that ARMA 2 doesnt like "Virtualisation technology". I disabled this in the BIOS and it has sorted it.
All graphichs settings set to high, with pp turned off (i just dont get on with it) and just finished the first mission with a very respectable avrage fps of 24.8.
This may not seem very high but it is extremley playable the only time it really drops is when staring at a helicopter whilst its kicking up dust everywhere. Even the bunches of trees aren't causing me hassle any more. The whole game just feels really smooth compared to before on all low settings when I was getting better fps but the game still felt sluggish.
