Most games do that for me...it takes a few seconds and then I get good fpsss.
Yeah, this is called texture loading. Your system loads all the games textures into the videocard memory. Thats why if you ever run a bench mark, like a doom3 time demo, or crysis or something, you go by the second bench run that way the textures are already loaded. This guy is talking about something different, texture loading doesn't drop you to 15fps on a gx2......actually sounds like some sort of driver issue to me. While it may be a senseless suggestion, i would go to the microsoft website and download the latest directx version. I have vista64 as well, and for some reason it didn't autoupdate direct x (yes, i have it set to autoupdate).
