@Dark Raven:
Nope, everything from new games (Crysis, CoD4, The Witcher) to old ones (VtM: Bloodlines, Oblivion, Doom 3) works perfectly fine. Except BioShock, but it's been f'ed XP, too.
@Gorth:
No new update for me, neither on their support page, nor through auto-updating.
Guess your's is higher because of you using a X-Fi Titanium Fatal1ty while I have to make do with an 'ordinary' X-Fi XtremeGamer.
There are beta drivers available though, released on 9/26/2008, but as they are beta - and since my X-Fi has been the only source for a BSoD as of yet - I tend to refrain from using them.
