Direct X 9c VS 10+

[daddog]

I have a GTX 260 card and heard I should download and use Direct X 10 or 10.1. Right now I am running 9c. Does it matter?

If you have XP, you can't use 10, you're stuck with 9.  If you have Vista, you should already have 10 installed.

Answers my question. XP here. Thank you sir.

Alky project is a hoax it never run a single DX10 game.

Hypothetically, if there was a way of running DX 10 on XP would there be any point unless you wanted to run a game written for DX 10? Wouldn't a game like AH which is written for DX 9 run just the same on DX 10 anyway?

well at somepoint they are gonna have to make the upgrade to DX10  .. you would think

Your exactly right, Aces High doesn't take advantage of DX10 and IMO there is little reason to. That's saying they would go about it like MS did for Halo 2 on the PC, it basically forced you to have Vista to play it because you "needed" DX10.

Not really, as I said above there are few reasons to. Granted DX10 does give some improvements in graphics in some areas, the amount of people here who seems to hate Vista(I'm one of them) would never use it... and from what I see even less people have GPU's that even support DX10 or 10.1. My guess is we won't see DX10 for a long awhile, and the game looks great now with DX9.0c so I'm not concerned.

Will DirectX 10 be available for Windows XP?

No. Windows Vista, which has DirectX 10, includes an updated DirectX runtime based on the runtime in Windows XP SP2 (DirectX 9.0c) with changes to work with the new Windows Display Driver Model (WDDM) and the new audio driver stack, and with other updates in the operating system. In addition to Direct3D 9, Windows Vista supports two new interfaces when the correct video hardware and drivers are present: Direct3D9Ex and Direct3D10.

Since these new interfaces rely on the WDDM technology, they will never be available on earlier versions of Windows. All the other changes made to DirectX technologies for Windows Vista are also specific to the new version of Windows. The name DirectX 10 is misleading in that many technologies shipping in the DirectX SDK (XACT, XINPUT, D3DX) are not encompassed by this version number. So, referring to the version number of the DirectX runtime as a whole has lost much of its meaning, even for 9.0c. The DirectX Diagnostic Tool (DXdiag.exe) on Windows Vista does report DirectX 10, but this really only refers to Direct3D 10.

it will never be offically released by microsoft but there is directX10 for xp ..

You're making it sound as if Microsoft made some underground version of DX10 for XP   Microsoft has no intention of making DX10 work on XP..  It's not even really possible to make DX10 work to the extent that there's any kind of significant difference or reliability..  I've seen guys run Crysis with an XP DX10 hack, but it crashes within a few minutes, if not seconds and there's really no difference in graphics..  Maybe a few lines on some of the leaves changed or something hardly noticeable, but the water looked the same (worse actually)..  I've read about some kids attempting to make ports of DX10 to XP, but the ones I've sampled are hardly reliable and hosed one of my systems (my test box)..

DX10 is so much slower than DX9 that it would make no sense to even want to run it on current hardware. It was a huge marketing trick basically. Visual benefits are diminishable but you get a performance hit. IMO DX10 is more of an addition to developers, they have easyer tools to work with but overall performance took a hit (.net anyone?).

No, it wasn't a hoax at all.  It was a legitimat attempt at making DX10 XP compatible but along the way they found out that they could only enable some features of DX10 to work in XP, namely some of the lighting/shadow effects in DX10.  Basically, DX9 with some .dll files from DX10.  Unfortunately, I didn't take any comparison screenshots to show the different lighting effects but in that regards, the Alky Project did work, there is a noticeable visual improvement over lighting and shadows.  There is also the added benefit of slightly better performance, though that I'm sure is more dependent on the system it's being run on.
