Vertex color rendering 'sluggish'?

General Discussion
1

I know that it is a dumb question that cares to 0 people but it is just to fulfil my curiosiity:
i’m slowly proceding to do a blender 2 egg exporter and i’m starting to see some working output where i’m pviewing all the polys in place and, as a second feature, i have added vertex colors. While pview throughput without vertex colors is, on my box, an average of 60fps when i assign a color to the vertices the render performances drop to 6fps!!!
Reading my .egg output i am unable to see anything wrong:

}

so i am wondering it is just me or what?

solved - after a good reboot the problem is disappeared
maybe something have chocked my graphic card
