Well i rolled back to XP and still got the problem lol
So i've went back to Vista and i am currently installing Arma again i've grabbed the new drivers so i'll see what happens,
are people seeing the good results with the beta patch + new drivers? or 1.04/1.05?
*Edit* Well i tried it with 1.04 and i have no lod or performance issue with everything on very high, however i do have a new issue lol. When i'm in the menu and occasionally in game my screen flashes white like a strobe light, stops, goes all white like a flashbang effect then fades back to normal again. This happens randomly. Seems as if it's something to do with the lighting
I'm Downloading 1.05 atm, will see if that helps
*Edit*
