I've got a Ti4600 and used the 41.09 before I up graded to the 43.51 because of a sound issue and I hoped it would help things, but instead FS kept crashing and things were slower on the 43.51, so I wen't back to the 41.09's and things are ok now except for the sound thing, it seems to be more predominant when any smoke or clouds are present,and even flying on vatsim too, I get tripple button clicks instead of single,and the sound is sometimes distorted too, any ideas here guy's.I'm running XP Pro with 1024mb ram on a XP1900 cpu and SP1.

What version of DirectX are you using? I wasn't happy with 43.51 either UNTIL I paired it up with DX 9.0a...Scott
