3d.view.sh script very slow on own data.

Hi !

I have modified 3d.view.sh to run on my own elevation model. The size of this raster file is approximataly 8 times smaler than the elevation.dem in the spearfish data set. However, the speed by which the screen is updated is approximately 50 times slower.How do I improve the speed of updating the screen.
