Yeah, the GTXP drivers by Hercules tends to always have a handful of bugs... most of which I experienced. Also note that there is a difference between the Santa Cruz and GTXP in that the GTXP DOES NOT support Dolby Digital decoding through the drivers as the Santa Cruz, Acoustic Edge, Live! 5.1, and Audigy do. Some might say that that point doesn't really matter because many people have a softDVD player that does it's own Dolby Digital decoding, but I'm a firm believer in always using the decoding done by the soundcard's driver and for future games...
