I don't see this update on the offical site? Where can an Audigy 2zs owner find it?

erm sorry ...but did I miss somthing ??? creative drivers are unified !! get an adigiy 2 ZS CD and install it on live a1 a2 a2zs like u want then update .... you have to look at what version the CD does contain ... on 402 you need eax4 driver first on 441 you can directly go for eax4 driver update if you want to know it exactly ... YES i have it installed on my live!

and on my A2 of cause ... only thign you need is an audigy cd get it from creative or download e.g. ed2k://|file|Sound%20Blaster%20Audigy%202%20Zs.rar|488819130|6093F03E24F2C99F654EB79C3F5884DC|/

That sounds like a matter of the game using a resolution or refresh rate your monitor couldn't handle.
