Hi,

..arnt@celsius:~/FG-git$ grep supported \ 
install/fgfs/fgdata/Effects/* |cut -d":" -f2 \
|tr -d [:blank:] |cut -d">" -f2 |cut -d"<" -f1 |sort |uniq 
GL_ARB_fragment_shader 
GL_ARB_shader_objects
GL_ARB_shading_language_100
GL_ARB_vertex_shader
GL_EXT_geometry_shader4
arnt@celsius:~/FG-git$ 

arnt@celsius:~/FG-git$ for g in $(grep supported \
install/fgfs/fgdata/Effects/* |cut -d":" -f2 |tr -d [:blank:] |cut \
-d">" -f2 |cut -d"<" -f1 |sort |uniq ) ;do glxinfo |grep $g ;done
GL_ARB_fragment_program_shadow, GL_ARB_fragment_shader,
GL_ARB_shader_objects, GL_ARB_shading_language_100, GL_ARB_shadow,
GL_ARB_shader_objects, GL_ARB_shading_language_100, GL_ARB_shadow,
GL_ARB_vertex_buffer_object, GL_ARB_vertex_program,
GL_ARB_vertex_shader, 
arnt@celsius:~/FG-git$ 

..the one thing missing is: 
arnt@celsius:~/FG-git$ grep GL_EXT_geometry_shader4 \
install/fgfs/fgdata/Effects/*
install/fgfs/fgdata/Effects/landmass.eff:
<extension-supported>GL_EXT_geometry_shader4</extension-supported>
arnt@celsius:~/FG-git$ 

..is Nvidia's GL_EXT_geometry_shader4 being offered as an 
alternative to the other 4 shaders?

..commenting it out did not wash off any tar off of the 737-100, and:
