Pci audio quality?

The architecture of the NV1 was not aimed at the Direct3D philosophy and, as such, game compatibility was a problem with the Diamond Edge boards. Limited and slow Direct3D-supporting drivers did eventually show up, but the boards were simply not up to the task and were unacceptably slow and buggy. It didn't help that the audio section of the card was not particularly excellent either, receiving luke warm reviews regarding MIDI quality (extremely important during the card's time).
