Well, I am one of the "few" who use Creative's X-FI series (fatal1ty), yes I am a gamer (also a developer (non-game related)). From creatives site: Quote>
With Microsoft's decision to remove the audio hardware layer in Windows Vista, legacy DirectSound 3D games will no longer use hardware 3D algorithms for audio spatialization. Instead they will have to rely upon the new Microsoft software mixer that is built into Windows Vista. This new software mixer will give the users basic audio support for their old Direct Sound games but since it has no hardware layer, all EAX® effects will be lost, and no individual per-voice processing can be performed using dedicated hardware processing.

EAX has become the de facto standard for real-time effects processing. It has been incorporated in hundreds of games and has become the method of choice for game developers wanting to add interactive environment effects to their titles. Some of the best selling games of all time use the EAX extensions to DirectSound 5.0 and beyond, including Warcraft3, Diablo2, World of Warcraft, Half Life, Ghost Recon, F.E.A.R. and many others. Under Windows Vista, these games will be losing the hardware support that came as standard under the previous Windows Operating Systems, and will no longer provide real-time interactive effects, making them sound empty and lifeless by comparison to the way they sound on Windows XP.

So I can't say I am too happy about this. Couldn't you find a way to not dissapoint high-end audio gamers? [C] Sad
