I installed the newest drivers from nvidia, but with no success. I go on searching, but perhaps someone, if he has a lot of time ;), could try to write a simple vertex shader for osgShadow::ShadowMap for passing texture attributes etc. to the fragment program. I tried it, but for me it is not working. If someone else could get it working I would know that the problem is on my site. Thanks to you Robert and everybody else.
