MS included an opengl -> direct3d wrapper in XP?

[Dan Corban]

This is interesting... trust me.

I have been using XP since RC1. I have a Geforce2. In RC1 and RC2 the
default video drivers included the Nvidia OpenGL ICD and all OpenGL games
worked fine. In the retail version of XP, the Nvidia ICD was not included
with the default drivers (for whatever reason). These are all well known
facts.

I have been using the default WinXP video drivers and today decided I would
start playing Quake3 again. Knowing there was no hardware OpenGL
acceleration I downloaded the latest Nvidia drivers. Before installing them
I went ahead and installed Quake3. Just for fun I ran the game. It loaded up
fine. I started a single player game thinking, "OK haha this is using
software OpenGL and it will run like crap". It ran perfectly smooth. Feeling
rather puzzled I went into the video options, and clicked on the driver info
to see what the deal was.

Microsoft stealthily included a hardware accelerated OpenGL to Direct3D
wrapper? When did this happen? I could find no hard facts about this, and
the MS Knowledge base has no mention of OpenGL at all in the WinXP category.
It is fairly obvious that there IS indeed some sort of OGL->D3D conversion
going on.

Anyone else notice this or have any facts or info about it?

I know when I downloaded the updated drivers for my ATI All in Wonder 128
PRO, the ATI site said that the driver that came with Xp wouldn't support
OpenGL. It said I would have to install the update from ATI to have it.

After some investigation, I have discovered what has caused this:
