Ok, I need as many of you to post in here as possible. I'm trying to point this fact out to a friend. If you have any position in the industry of gaming development and such and know because of being in the industry, please state that too. Ok, aren't I right in saying that DX9 cards do not, and will not ever, support DX10? DX9 cards were engineered to with the unique logarithms of DX9 software. DX10 was built from the ground up, with a completely new, and unique set of logarithms, and is not compatible with cards engineered to work with DX9 logarithms. In other words, DX9 cards were engineered to work with DX9 and before, exclusively. You can't just update them somehow, because unlike DX9, DX10 was build from the ground up. So DX10 will not, and never will, work on DX9 cards. If you agree please post in accordance to what I said above. Thanks!

Technically no.

DX10 as in most previous versions of DX incorporate changes and features that older cards are not designed to run. Therefore a new card is designed to support those new features.

IIRC Virtualization and Pixel shader 4.0 are the main features.

Direct sound has been dropped and replaced with XACT standard and drops completely hardware audio processing and runs audio now through software making those of you with your nice and expensive new sound cards useless.

Asus and Creative Labs are supposed to be working inn a workaround to do hardware acceleration and still be Vista compatible.

DX10 has IIRC some virtualization features that a DX9 card cant support.

Any DX card should be able to support the previous versions of DX.

DX9 cards cannot support DX10. As Anlushac11 stated, Pixel Shader 4.0 and IIRC Virtualization are the newest features of DX10. DX9 cards aren't engineered to do that kind of stuff. Unless you can find out some sort of hack that will enable DX9 cards to run the features of DX10. They won't be able to run DX10.

Also despite some cards having faster core speeds and faster memory speeds it seems many DX9 cards are running DX9 apps better than DX10 cards do despite the fact hat DX10 cards are supposed to be backwards compatible.

I expect alot of this will change in time with driver optimizations.

Now what I do argue about is whether DX10 can run on XP. It can.

DX10 required memory virtualization which ATI pulled off very well and Nvidia couldnt get going right. Microsoft has since dropped or changed the virtualization part so Nvidia could run. That was hte only hardware reason XP could not run DX10. Now that that has changed there is no reason MS cant release DX10 for XP except that they wont siimply to boost Vista sales to prove Vista is the most popular and bestest O/S since XP.

I think it is able to run on XP but only for video games supporting DX10.

Its highly unlikely that they will.

Vista has DX9 and DX10 support built in so Vista will run on a DX9 card, but you will need a DX10 card to play a game to get to see the DX10 features.

It still won't. DX9 cards simply do not have the required hardware and features to run DX10.

To use DX10 = Vista and a DX10 card.

OH!! So DX10 won't work with XP. Dammit. That screws me over in that department. I run XP XP2 and I have a 7600GS. Was about to get an 8 series card and try DX10. But I might still get it considering it pwns the sh*t out of my 7600GS.

Anlushac11, I think you are missing the point. I'm just saying that a Directx 9 card will never be able to run Directx 10.
