Sorry Im so late to reply. Well, I guess that pretty much clears things up for me; a single physx card is useless, at least with Batman AA. Not a big deal I guess seeing as how the 9800 is still leaps and bounds better than the HD3450 I was using
. My CPU is an AMD athlon 64 x2 5000 brisbane. Furthermore, if the physx is going to hurt my performance when playing Batman AA, where/how can I disable pysx entirely? I do not see the option in the game's menu nor in the nvidia control panel. All I can see is where i can tell it to use the cpu or gpu.
