The OpenGL error "glProgramParameteri not supported by OpenGL driver" is
a message that will be displayed for everyone that is using shaders in
their application, but doesn't have support for Geometry shaders on the
GPU.

Subject: [osg-users] What changed with ShadowMap in 2.3.x?
Hi Robert -- osgShadow::ShadowMap no longer produces correct
results for me in 2.3.x, though 2.2 still works fine.
In 2.3.x, I now get the following displayed when I execute an
app that uses ShadowMap:
Error: glProgramParameteri not supported by OpenGL driver
I'm reluctant to upgrade drivers as newer NVIDIA Windows drivers
kill performance for occlusion query. Is there an environment variable
that will make ShadowMap behave like it used to in 2.2?
Thanks.
