I have an Audigy 2 ZS, but I can also only choose 'Generic Software'. Does this slow the game down, since the processor handles the sounds now - and this is an processor intensive game? I ask this because I suspect my framerate is too low. I have a AMD Athlon 64 3200+, 2.01 GHz 2048 MB DDR 400 MHz 7200 RPM HDD's Asus 8800 GTS 320 Mb Creative Audigy 2 ZS
