This is what I get:

GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context
client glx vendor string: SGI
client glx version string: 1.2
client glx extensions:
GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context
GLX extensions:
GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context
OpenGL vendor string: VA Linux Systems, Inc.

The direct rendering is set to No. Does this mean that my video card
handles most of it, or just the contrary?
Compared to some other outputs I have found, this seems like a rather
poorly GL support. Am I still missing something (configuration parts,
libs, etc)?
Thanks!

NT is the OS of the future. The main engine is the 16-bit Subsystem
(also called MS-DOS Subsystem). Above that, there is the windoze 95/98
16-bit Subsystem. Anyone can see that 16+16=32, so windoze NT is a
*real* 32-bit system.
