The application seems to draw the entire scene using lots of d3d_device7_DrawPrimitive() calls with small vertex counts (< 30). That's sub-optimal. This results in lots of small buffer maps, and I have the impression that maps in general are relatively expensive on the proprietary nvidia driver. The attached path seems to help for me, although it may be too specific to the application and driver combination to be of general use.
