I searched the forums and didn't find anything related, if so sorry. I was thinking of holding off for a DX10 video card but now I don't know. I'm not to excited about having to buy Vista just to have DX10. My plan was to wait for a year after Vista is released to purchase it. I think Microsoft is trying to force everyone to upgrade to Vista which sucks.
 
This has been beaten to death, but yes, DX10 will not be supported in XP. Conversely, in Vista, you will be able to run DX9 titles.

Whether or not they are forcing people to Vista is debatable. IMHO, they figured it was simply time to cut bait on some old code and make things more efficient, which is fine by me.
 
Indeed. There is always confusion (among the ill-informed) when discussion of DirectX 9.0L comes up, but only because of hopeful naivete. DirectX 9.0L is for Vista only (the 'L' stands for 'Longhorn').

Essentially, DX10 is a *completely* re-write of DirectX from the ground up. All previous DX versions were built on previous code, so if you upgrade to DX9, you could still play DX8 titles...all the API calls were 'still there'. Each release just added new ones.

DX10 is different. There is no DX7/8/9/etc code or functions in it. So no DX7/8/9/etc games will work in DX10. That's why Vista will ALSO have DX9.0L (existing in parallel with DX10). It will allow DX9.0 games to run at all on the OS.

So, in recap - DX10 is a complete re-write. More efficient, more features, faster, and completely impossible to port to Windows XP due to radical differences in interaction with the OS. Oh, and no backwards compatibility. DX9.0L is the DX version that will allow Vista to have some backwards compatibility. (There would be no reason to have DX9.0L on WindowsXP, anyway, as all it is is DX9.0C built for Vista)

You said it. This has been my gripe with all the people who crawl out of the woodwork on this topic to say, "They COULD make it work in XP but they won't, greedy !@#$%'s!!!" Not understanding (or refusing to understand) that the work that would have to happen to make XP compatible with DX10 would be to rewrite XP--which they've already done! It's called... wait for it... Vista!

I mean come on! It's like saying, "Hey, I can turn my Nissan 350Z into a Ferrari Modena. All I need is to buy a Ferrari engine, and a Ferrari body, and a Ferrari chassis...."

Oh, and to the OP: In other news, scientists have demonstrated conclusively that the Earth is not flat... just in case you missed it...

The real amazement is that this was a suprise. :rolleyes:

I'm suprised that the Inquirer et al.. are not posting articles about how DX10 is also not supported in OS X :D
 
I thought DX10 was going to be backwards compatible for XP. This was news to me until today. I seriously thought I could be able to play DX10 games on XP. The way I understood it is that I will be able to play DX10 games on XP but not utilize all the good graphics.

Yes, Commander Suzdal, I know the world is flat, jeeze.
 
Yep DX10 =Vista only
but there will still be support for DX9. It's called DirectX 9.0L (legacy)
 
I think you and dderidex need to talk because you two are saying two completely different things.

Actually, the only thing different is the word they believe L is meant to describe. L does stand for Longhorn as far as I know (wikipedia agrees), but I have also heard it as Legacy and Layer. Etiherway, everyone agrees on what it is- Vista's version of DirectX 9, basically an API replicating DX9 classes and functionality over DX10.
 
[H]ardOCP published a whole article on this. *sigh*

XP will not get DX10. The only way to game in DX10 is with DX10 hardware and DX10 software on Vista, only Vista, and nothing but Vista.

You can (for now) still install DX10 games on DX9 hardware/XP, but they will run in reduced eye candy mode. I'm not sure how long that will last though, with the new shader model and physics stuff on the way. Surely at some point there will be a DX9 cut-off, same as <DX6 is no longer supported, and most games require DX7 hardware (or higher) to even run in crap mode.

Can you put a DX10 card or software in an XP system? Yes. Will it run in DX10 mode? No.
