Hi Adrian, Thanks for you quick reply.

The problem is that it is painfully slow on the 7300LE cards, eating 100% of the CPU with just 3 SceneView objects. ShadowTexture runs great on these cards, but it doesn't use any shaders, so I was wondering if it could be some GLSL extension those cards were missing or maybe the fact that they are running NVidia driver version 100, instead of 169 (the latest). We're running on Debian Linux. These are (some of) the messages I get from OSG, maybe the can be of help: OpenGL extension '' is not supported.
