I think the problem has to do with some GLSL extension in use by the PSSM shader which is not available in the NVidia GeForce 7300LE card. I've ran my application on both cards (7300LE and 8600GT) with OSG_NOTIFY_LEVEL=DEBUG and found some extensions missing in the 7300LE card which are present in the 8600GT card. These are: GL_EXT_geometry_shader4, GL_EXT_gpu_shader4 and GL_EXT_texture_integer. Is any of these 3 extensions actually needed by the PSSM shader? Thanks, Alejandro.- PS: I haven't been able to get the InfoLog output, it appears to be always empty. -- [EMAIL PROTECTED] http://varrojo.linuxuruguay.org
