You do not get LOD fading on your geforce since it would be a huge
performance hit. LOD fading requires either multisampling, which is slow
on a GeForce of any kind, or stippling, which is very expensive as
well, so performer decides not to fade LOD's. You could force the
selection of a multisample visual by setting the environment variable
PF_ENABLE_MULTISAMPLE_VISUAL to 1 and setting the appropriate nvidia
environment variables as well.
