Those game cards also support OpenGL. There are actually more OpenGL cards
than DirectX 10 cards.

No, the CAD industry have been complaining to MS about this for over a year.

OpenGL has been a stable and mature technology for a decade, thanks to
Silicon Graphics. It was DirectX that has been trying to catch up to
OpenGL. MS adopted OpenGL in the early days of NT to encourage Unix-based
CAD programs to port to NT. Now that this has been done, MS is backstabbing
the industry, and they don't like it one bit. Several have told me that
there is no way they will port, and their customers will stick to XP rather
than use Vista. There is a _lot_ of talk of it being easier to port to
Linux and Mac, rather than convert to DirectX. Let's see who blinks first.

from the 10 or so people I know who use CAD only one uses velum. Autodesk
is the 900 pound gorilla. And while I hate installing Autocad and going
through the ms like activation hoops that is what everyone just uses
AutoCAD does not use OpenGL and is not affected by this. It is all the
higher end 3D CAD programs, like Solidworks, SolidEdge, CATIA, ProEngineer,
Unigraphics, Alibre, IronCAD, Think3, Rhino, and so on. 2D programs have no
use for OpenGL, only solid modelers and other such 3D programs are affected,
but this is the stuff that lies at the cutting edge. AutoCAD is old stuff,
and 3D modelers like Solidworks are growing like wildfire. My
Solidworks/FEA machine is a quad Xeon with 16GB of RAM, if that gives you
any idea of the level of power we are talking about. At this level, the
application dictates what OS is used. MS worked hard to get into this
market and could easily lose it. This is where all the 64-bit action is
happening.
I'll be visiting the Dassault and Solidworks folks this week. This is one
of the topics we will be discussing.

I'll be interested to see how some of the larger game dev shops
handle
this. Id Software is a big proponent of OpenGL and they have a lot
of
weight in the industry. Microsoft may find itself without a viable
PC
platform for games if they're not careful.
Id are two faced monkies. They are apposed to directx in there pr but they
make directx optimized games. They said they would support project rhapsody
with id games yet id has only a very small selection on non stellar titles
for OSX ( orginal code base for OSX was project rhapsody) id comment to
apple and rhapsody was outline in Boot magizine with McCormick being
interviewed by ex - ms direct x spin doctor Alex Saint John.
I dont see game companies throwing there wieght behind opengl. If they did
there would be optimized opengl cards instead of optimized direct x cards (
With the notable workstation exceptions of the ATI FireGL and the Nvidia
Quadro series of cards )
This is unfortnately another example of people crying foul way after the
fact. This was another area that other people let Microsoft take control
over of. Part of the reason is the slow moving process of adding new
features to opengl, while directx development progresses. Now that MS won
the gaming api war they have control over what people buy. If they want to
play a directx 10 optimized game then there forced to buy Vista.
While I know and have seen this CAD program velum before this article from
the 10 or so people I know who use CAD only one uses velum. Autodesk is the
900 pound gorilla. And while I hate installing Autocad and going through
the ms like activation hoops that is what everyone just uses.
My question is to them why linux now and not linux 2 years ago. They only
want to move do to ms crippling opengl support ( which will probably be
fixed eventually ) but it seems like to me as nothing more than a marketing
ploy.
