Hey you guys. I have come up with a few settings tweaks for X-Fi and Vista and XP users to get the most out of their sound cards. This tutorial will walk through a Vista setup (however, it's almost identical on XP). I have found these settings to give superb audio realism not only in Crysis, but also in general music playback:
First off, open up the Creative Audio Console. If you don't have it already, you can download it here:
Vista x86 / x64:http://ccftp.creative.com/manualdn/Applications/AVP/10434/0xA7102A72/ALXF_PCVTAPP_LB_1_00_30.exeXP x86 / x64:http://ccftp.creative.com/manualdn/Drivers/AVP/10469/0xE545059D/SBXF_PCDVRBETA_LB_2_14_0001.exeMake sure you are in Game Mode for these settings (and apply the same settings to Entertainment Mode):

Set your speaker configuration based on the type of setup you have:

Enable X-Fi CMSS-3D, set the Stereo Envelopment to 60% and make sure Stereo Xpand and Auto Upmix are on

Set the X-Fi Crystallizer to 85% (you may set it according to preference, but in my opinion it sounds best here)

Next, open up Creative Alchemy X-Fi. If you don't have it already, you can download it here:
(not needed for XP users)Vista x86 / x64:http://ccftp.creative.com/manualdn/Applications/AVP/10434/0xA7102A72/ALXF_PCVTAPP_LB_1_00_30.exeClick on "Add", title the game "Crysis", and use the following settings:

Finally, if you really really wanna boost your eargasms in this game for intense sound The Way It's Meant to be Heard (lol pun on Nvidia), I have come up with some sound tweaks. Add these lines to your autoexec.cfg file if you have one in your Crytek > Crysis folder. If you don't already, search these forums, and there's plenty of info on how to make one.

PS: If you have Logitech G51 speakers or any speakers with Matrix mode settings on the volume controller, NEVER touch these features. They bring nothing but distortion and overdriven sound quality out of your perfectly beautiful X-Fi Fatal1ty's sound processor. Just set your subwoofer to the 3rd orange volume light, your surrounds to the 5th one, and your center to the 2nd one and you'll be good to go
