Wow, thanks for the quick response guys, thats fantastic! I've lowered the res to 1024x768, and set the graphics to their lowest level. Its bumped it up to between 28-34 fps now. Surely I should expect a larger return than that? going from 1680x1050 all medium high, to 1024x768 with everything on lowest. looking at my cpu usage it never actually maxes out any of the threads. It taxes the 1st 1 pretty hard, and the rest are all running at 50-60%. Even when I set arma 2 to run 'high priority' in task manager. Going into the armoury and playing about in the environment I can hit 50-60fps at nearly all the highest settings, so I dont think im limited by my graphics card. Infact, credit to Bohemia, this game really does look incredible when it wants to. Im gonna rummage around all the performance tweak guides available, but does anyone know off the top of their head im BIS are gonna patch the campaign or anything? Maybe tweek performance or anything like that? Im not a graphics whore or anything like that, but I really cant stand choppy gameplay. I look at videos on youtube of people playing the campaign on slightly older hardware and their performance seems to be leagues ahead of mine. Again thanks for the quick response
