I read the DirectX 10 (D3D10) article a little bit, and learned, itll only be for Vista OS.

Now, ive heard (and think its bs) that for Windows XP theres going to be a version called DirectX 9.0d for Windows XP which substitutes for DirectX10 on Vista.

Is this true? or am i right of thinking its just bullshit?
 
Very close... right on all aspect, except for 9.0d it's going to be called 9.0l

l = "L"
 
no new DX for XP from what i have heard and 9L is the DX9 emulation layer for DX10 iirc

Correct, DirectX9l is what Vista will run previous DirectX9 games in.

There will be no option to run DX10 under XP.
 
9.0l is Vista only. I don't know where that stupid rumor got out about it running DX 10 in XP came from.


Oh wait, faud. Duh.

I wish some third party was allowed to develop a replacement for DirectX, that I could use/buy for less than an arm and a leg....I have no desire to buy windows Vista, apart from gaming....it's SO expensive.

They do, its called OpenGL :p
 
DX10 games will not run in DX10 under XP, if you really want all the extra speed and/or IQ that DX10 hardware will be capable of, you are going to need Vista. Period. Now all we need are the DX10 games and Vista right? :rolleyes: :p

OpenGL won't play DX titles. The person you quoted is wanting something that isn't DX (i.e. only from MS), but will still run DX titles. Sort of like WINE for Linux. That's how I understood it anyway.
 
windows vista really isnt that expensive so idk what you guys are talking about. its like 159.00 for an upgrade.
 
I wonder why for decades Direct X is the only API available. I know OpenGL is still there but this looks like theres some room for development.

It surely isn't the only API available, as you mention OpenGL. Just so happens, that inertia for game development has led a bunch of programmers to stick with DX. They knew it, so it's easier for them to code to.

OpenGL is coming out with a new version (can't recall the nomenclature for the release atm) which will contain a bunch of features that are comparable to those in DX10. Carmack has always been a huge proponent of DX as we all know, but he did say at one time that he thought of switching to DX because the version of OpenGL he was working on at the time was a pain in the a$$. That never came to fruition, of course.

And just to re-iterate for the OP, Direct X9l is for VISTA, and allows it to run DX9 games. No DX10 for XP, period.

DirectX 9.0L is legacy DX9.0c support for Vista. It is NOT DX10 for XP, nor will there be any DX10 support on XP at all.

No, the original version of the post you quoted is correct. Vista's support for DX10 is called DX10, not DX9.0L :rolleyes:.

Um, no he had it right. DX9L is so that Vista can run DX9 games.


I wouldn't be too terribly surprise if MS decides to release a hobbled version of DX10 for XP down the road.

I doubt it. The major selling point of Vista to gamers is DX10 support. Microsoft would be shooting themselves in the foot if they gave DX10 support to XP, since that would lead to less sales of Vista.

One could say they did the same thing with
WinFX
Sidebar
IE7
WMP11
Avalon
Indigo
.net 3.0 (i believe this is being backported to XP)

To my knowledge, only IE7, WMP11, and .net 3.0 will be(or are) available for XP. There's also a difference in the two situations. There are alternatives to WMP and IE on XP, so if they didn't port the newer versions to XP they'd be leaving the market open to other solutions. They're just trying to keep their existing marketshare of those programs on XP to prevent people from switching to non-Microsoft alternatives. However, DX10 does not have a viable competitor, since there is no other technology that can use DX10 effects. Therefore, they have no competition except for themselves, which is why they'd want to give Vista an advantage over XP so more people migrate.
 
Im not sure if this question was asked, but if I run windows vista with 8800GTX card and Quad core cpu would all games work like the last few years? thanks
 
DX10 is built upon an entirely different driver model than DX9, a driver model that isn't at all compatible with XP. Could MS build a wrapper to go around it? Highly doubtful, although I don't know all the ins and outs of it, so maybe. But from everything I've read about the security and memory handling aspects of the new driver model I don't see how they could make a wrapper around it to make it work with XP. Plus, would you really want that anyway? Imagine how slow that would be.

None of those other things mentioned (WinFX which is now .NET 3.0, IE7, etc.) share that same limitation/feature, which is why they are being ported to XP while DX10 isn't.

Will be interesting to see if Nvidia / ATI bring OpenGL extensions for the new direct3D 10 features (like geometry shaders) to Windows XP (and Linux of course).

(and just nitpick, OpengGL is a replacement for Direct3D, not for DirectX).
 
if I have two bootable drives 1 xp and 1 vista, games should work in xp and games that
have dx10 work in vista? If thats correct

They will, if they want to remain a viable alternative to DirectX(Direct3D, my bad :p). I'm sure the iD crew will see to that, since they're pretty much the biggest company that uses OpenGL exclusively.

Why not just have Vista for DX10 and DX9 games. That's what DX9L is for anywya. And supposedly it's just as fast or faster than DX9c is on XP.

thanks, I didn't know that you can use dx9 games in vista?
that makes it alot easy using only windows vista thanks

Yes, of course you can play DX9 titles under Vista......all versions of Direct X are backwards compatible, hence that is why you can play old DX7 games under XP, which is DX9.
 
Just wait till Dx10.1 throws you for a loop lol..... wouldnt it be something if the 8800 refresh and ati's responce are 10.1 by then..

Actually DX10 isn't compatible with DX9 or before. That's why there's DX9L. Question is though is DX9L (i assume the 'L' means light) backwards compaitble with DX8, DX7, etc?

I am clearly not an expert in the inner workings of directx,
that said, there aren't a lot of differences between DX8 and DX9. It would seem silly to me to migrate DX9 to Vista, and not bring DX8 with it.
DX7 on the other hand, you're talking about brining back DirectDraw (which is not part of DX8 or DX9 - Direct3D is the only component that draws to the screen now). Considering the relative age of DX7, if it's more than trivial to move over to Vista, I wouldn't bet on DX7 games in Vista.
 
DirectX 9L is compatible with all previous Direct X versions.

There are hundreds of reasons why several games won't work on Vista, but DX compatibility won't be one of them.

True, I wasn't specific enough, but yeah, the L version should be back compatible with 7 and 8....

besides the $$$, i heard that it only allows one copy of the it's OS to run only on 1 machine, wtf? how about people who build PC's yearly?
Well i just read that they have change that policy

This is what happens when you let Microsoft control something. Once they get their greedy paws on it, they start charging for it somehow.

Hope to see some developers move back to OpenGL. I can dream, can't I?

To home premium.

Most people here are going to be wanting to run ultimate, or POSSIBLY business.

This has been, technically true, for a long time. Installing your windows XP on two computers is a crime, and has always been. If you own 5 computers, and installed the SAME windows XP cd on all 5 of them, you are committing, every day, 4 counts of piracy, for example.


The other variation of the policy was that microsoft was going to make it difficult to TRANSFER licenses, however, they have relaxed that problem.
The item you linked STILL doesn't mean that you are allowed to run your SINGLE copy of vista on two or more computers.

Um... Microsoft created DirectX. The changes they're making are also for the better. They're taking advantage of the new Vista driver model to use DX10 to do things directly on the card that wouldn't be possible in XP. It's theoretically possible to make a DX9 wrapper for DX10 so it can be used in XP, but performance would be drastically slower.
