Yes, it's possible to buy hardware that has crappy opengl support. This
is true for any operating system. Many of the fringe players in the
video card market don't even have features on their card that could
support opengl well. Microsoft doesn't directly support opengl on all
hardware, and that also makes sense. OpenGL is in large part a driver
interface to the video hardware and MS can't be expected to write
drivers for everyone's hardware.
So the moral of the story: If you think you might want to run an OpenGL
based program, carefully consider your video hardware when you purchase
your computer. Nvidia and ATI typically provide excellent opengl support
for windows. nvidia provides excellent opengl support of linux/freebsd.
It pays to shop, know what hardware you are getting, and don't just
purchase something blindly. This is especially important if you are
purchasing a laptop, because you can't just drop in a new video card
later if you find out the built in video hardware has crappy opengl support.
There are too many important programs that use OpenGL for MS to even
consider tricky ways of killing OpenGL on their OS's.

Programs that Require OpenGL Support May Not Run in Windows XP
View products that this article applies to.

Article ID : 285912

SYMPTOMS
When you try to use programs (such as DVD players or games) that
require support for the OpenGL standard for three-dimensional graphics
display on your Windows XP-based computer, you may experience some or
all of the following symptoms:
• The software or game does not run.
• The display appears jagged.
• Pure color is missing.
• Different shades of color are not displayed to give the
three-dimensional look.
• Some or all colors are displayed incorrectly.
CAUSE
This behavior can occur if your video adapter driver does not support
the OpenGL standard.
RESOLUTION
To resolve this issue, contact your video adapter manufacturer for
information about how to obtain and install a Windows XP video adapter
driver that supports the OpenGL standard. Note that you may be able to
use a Microsoft Windows 2000 video adapter driver on your Windows
XP-based computer.
STATUS
This behavior is by design.
