I wouldn't worry about the "not supported" entries as these are for features that osgVolume doesn't use. More telling are the lines: glValidateProgram FAILED "" id=1 contextID=1 infolog: Texture unit 0 is accessed both as sampler1D and sampler3D I've just looked at the RayTracedTechnique.cpp and the fragment shader and haven't spotted anywhere where the textures are assigned to the same unit, or where the wrong sampler is used. Could you try the osgVolume property settings that don't require the transfer function to be used, this will give you a simpler shader and less room from the driver to screw up.
