Currently schedule for late release in 2007 and there are about 3 video
cards on the market that will be compatible.

You make this stuff up? Scheduled for release in 2007?? Where do you get
this stuff? Lets have a reliable pointer.

I'll give you one that suggests you know not of what you speak...
http://msdn2.microsoft.com/en-us/xna/aa937781.aspx

The above link will take you to Microsoft's Direct X developer center.
Scroll down a bit and on the right will be a link... "directx 10 on xp?"

Click on it.

There are three replies for you to read.

Now, show me your link.

I'd be very interested in this link as well. While I'm sure MS
intended (or still is intending) DX10 to be Vista-only, no game
developer in their right mind is going to develop for an OS and
video hardware that only a relative few people are using, at
least for the next few or several years.

DirectX10 has been written to be an integral part of Vista, not a
bolt on for other OS. In the past the purpose of directx was as a
quicker router to hardware than the desktop. Vista is designed to be
more efficient at the low level, so instead of bypassing the low
level, direct10 works through it.

DirectX 10 eliminates all the legacy support for previous DirectX
versions. This is a great thing since they can concentrate on new and
future technologies. DirectX 9.0m will allow for backwards
compatability.
That being said, there is really no reason DirectX 10 can't work on
XP since the foundation between the two OS's is nearly identical.
Vista is nothing more than a glorified XP with a fancy front end.
Sure there may be some enhancements, but probably nothing that
couldn't be done in XP and as efficiently.

Bull****. You clearly know nothing about the driver models in either XP or
Vista. The Vista video driver model is completely different to XP's. DX10
requires WDDM and WDDM would mean radical surgery to XP. WDDM is predicated
on a 3D UI whereas GDI+ is predicated on a 2D UI. Furthermore, in Vista
GDI+ (for backward compatibility) now sits on the DirectX Runtime, unlike in
XP where is sits on the GDI XPDM. All the other driver models have changed
in Vista too. Like it or loathe it, the fact remains it's completely new
code on a significantly different architecture.

If you were here during the switch to DX9, then you should know that that is
NOT how it goes. Usually, the games that come out during the transition
period work with the previous DX version, while they have EXTRAs for the ppl
with the new cards and the new OS that support the new DX version. A current
example is MS Flight Simulator X. It's already out, but MS will release a
DX10 patch for the game, adding new stuff into the game for those who paid
the big bucks, buying a DX10 card, and Vista. If you have a DX9 card and XP,
you can still play the game, but you won't see the new bells-and whistles.
That's it...

In short, no, no developer is crazy enough to release a game that would
exclusively support DX10 (unless they get some serious compensation from
DX10 card manufacturers and/or MS, which MAY be the case with Crysis).

I doubt it will ever happen for several reasons...but Microsoft did say they
will release Service Pack 3 for Windows XP in 2008 and it is said they will
backport some of Vista's features into it. They were originally planning to
release the service pack this year for XP but did not want to draw attention
away from Vista. Regardless, I would not expect DirectX 10 in SP3.

No. DX 10 is designed as an integral part of Windows Vista's architecture.
It cannot be adapted to XP.

I was wondering if it's not just a marketing strategy of MS to force
everyone to buy Vista.
After all, Windows XP is a perfect platform for games (and DirectX 9
was available for Windows 98, 2000 & XP).

But it is still a 'bolt on' from its inception. DX 10 is integral to
Vista at a lower level. DX9c may well be the top end for XP.

Actually, many people think it is just a marketing strategy. Microsoft
is struggling to give people reasons to switch to Vista.

Microsoft may say DX10 is firmly rooted in Vista's driver model.
However, that's like saying Windows cannot function without Internet
Explorer or Windows Media Player.


Yeah M$ keeps telling the Feds that, don't they?
McG.

Yep, and of course the EU and the South Korean government aren't buying
that.

Then again, there's a running joke in the Dailytech forums that the EU is
conjuring up new fines for Microsoft just to bail out the Airbus A380

I seriously doubt they could get that much out of MS even if they sold
off the company and took all the sale as cash.

They (MS) also took a hit today when the Feds said no to upgrading for
at least 6 months or more. Comment was they had no valid reason and
nothing to gain by upgrading.
