Cory, I've tried several versions of the nvidia driver and based on what I see and what I've read in the nvidia forums the interlace feature of the driver doesn't work correctly. The 1.0.6xxx drivers all double the scan lines, effectively halving the resolution. The 1.0.7xxx drivers seem to drop the second field, leaving gaps in the picture. I've read that this affects the fx series as well as the 440mx. Are you sure that you're getting an even and odd field that are different in your setup? If so, is there some extra options you passed the driver? Thanks.
