I just had the oddest turn around in performance in Arma 2
i had tryed the Beta after Grey's suggestion and got 15FPS in the Benchmark.
Now i just ran the Arma 2 1.05 version which is the official version at the moment through steam and scored 64FPS
so i guess i'll just stick to the latest offical Version for now
Anyway thanks for all the help guys,i hope it was not just a fluke,but that it stays at that level of FPS.
