I have 2 4850's Running crossfire, and I know that 1 4850 is more then enough to run Counter-Strike, but does crossfire work with it? what iImean by that is when there are around 4-5 Smokes in 1 location my FPS drops to a staggering 45-50 FPS which shouldn't be happening! what do I need to do to stop the graphic lag then there are smokes, I have the hardware to support it but how do I get it to work properly?
