Also have a RZ424, no updated drivers are available yet for the soundcard, but a later driver from nvida (2/7/04), cured my little niggles with MS Flgt sim 2004, file version: 2.11.15.0.
Hope this is of use to you.
PS: I have all options/visials at their highest levels and have not had any problems, but still have good frame rates.
Hope this helps!
