It seems a number of people are no longer able to open SLViewer version 2.7.4 and newer. The problem apparently started in June 2011. So, what is the problem and what is the fix?
nVidia and Second Life Shaders
Some change in the Second Life render pipeline’s shader code has created a problem between the nVidia driver and the OpenGL drivers used by Linden Lab in the viewer. It appears the nVidia GeForce GTX 460 card with any driver newer than 260.99 has a problem. If the graphics level is set at the default or on High or Ultra, the viewer crashes on login.
The problem does not exist in the nVidia driver 260.99 WHQL and presumably earlier drivers.
