Before I begin this, here are my PC specifications: AMD Phenom II X4 850 Processor 3.3 GHz 8.2 GB of RAM Windows 7 Ultimate Edition 64 bit GeForce GTX 550 Ti 1GB I have already changed the Arma 2 and Arma 2 OA txt folders (where you change these numbers to 1 on all the txt files). I seem to be getting an average of 15 fps with very low and very high settings. I haven't defragged in a long time, my other games run 30-60 fps consistantly (Minecraft, Battlefield 3 High, Garry's mod, Just Cause 2). Any help would be appreciated!
