Microsoft Announces DirectX 10.1 Preview

Microsoft is making a tech-demo version of its upcoming DirectX 10.1 available via download, including a version of XAudio2, the company's cross-platform replacement for DirectSound.

Users can try out both via the 468-Mbyte version of the August 2007 DirectX SDK. There's a catch, though: the August 2007 Direct3D 10.1 Tech Preview requires the Windows Vista SP1 Beta which will be available to MSDN subscribers once it is publicly released, according to Microsoft.

According to Microsoft, "Direct3D 10.1 is an incremental, side-by-side update to Direct3D 10.0 that provides a series of new rendering features that will be available in an upcoming generation of graphics hardware." The XAudio2 technology is also used in the Xbox 360, and will eventually replace DirectSound as the PC's main audio driver, according to Microsoft.

This information concerns me. I have an X-Fi Elite Pro card.

Is XAudio2 going to be better than EAX?
Is Creative X-Fi Drivers going to support this XAudio 2?
Is XAudio2 only going to be 5.1? (What about 6.1 & 7.1?)
What about OpenAL and XAudio2?

What is the difference, and more to the point why didn't microsoft just licence creatives EAX technologies, as that is where its at with all the top games. And believe me I enjoy my surround sound on games.

Help???!!!

What's the difference between OpenAL and Xaudio2 ? As far as Vista is concerned OpenAL has allready replaced Directsound and DX10+ will only be for Vista anyway so...

Apparently Xaudio2 is going to be another proprietary Microsoft technology that only works on Vista, while OpenAL is basically the audio equivalent of OpenGL, open source and free for everyone to use on any OS they want. Guess which one I'm rooting for...

Xaudio has some unique features not present in other Sound implementations like Room correction.
You are out of luck if you are using Creative's implementation -- most of these unique Vista audio features will not be available to you.

You can use this on any sound implementation lacking DRC, so I guess it's not such an unique feature.

more interested in wether Xaudio2 will allow hardware access and thus more efficient sound processing than than the software ased openAL. and if the difference is similar to DirectX vs OpenGL.. yeah I know which one I'm rooting for too. There are many things to be said about MS, but their proprietay technologies in this case are better than the free alternatives.

The only problem is of course if Creative ends up with another EAX situation and can monopolize game audio. But if it's the same as in the 360, I wouldn't worry too much.

What are you talking about? OpenAL allows hardware access.

Regarding DirectX vs OpenGL, you might want to show some proof to back your statement.

Also, Creative does not own OpenAL. They do most of the work on it but it's open source, you do not ever have to worry about them monopolizing it because they can't.

Sorry to be blunt, but you don't know what you're talking about.
OpenGL's performance on Vista is no better or worse than DirectX's performance on Vista. Some companies released crappy drivers at first, but this was their fault - not Microsoft's and not the API's.

Try reading up on some of the facts before jumping to such conclusions.

OpenAL uses hardware acceleration if it is available.

That's great. So now everyone who bought a DX10 card is screwed. I doubt any games will be using these features for a long while, though. Just can't wait to try SP1. :P

I'm not sure, but they may be.

I guess I'll continue to stick with DX9 for now, and wait for some real DX10 hardware to be released. And some DX10-only games worth buying. Going to upgrade my motherboard, CPU, RAM for now.

Does anyone know if the 8800GTS 640MB will support 10.1? I spend 450$ on this card over 8 months ago and dont want to get a new card that support 10.1.

Sorry dude, you're **** out of luck. But don't worry, you wont be missing out on anything for a few years to come.

- you should know how computer standards work. new stuff is coming out all the time. don't you think those who bought a DX9/SM2 card felt a little weird when the Shader Model 3 cards came out later?

- if you have enough disposable income to make such a purchase in the first place, then you have enough to buy a $450 10.1 card.

I'm so glad I waited before dropping the dime for a new video card. I'm still on DDR1, AGP but running a C2D. I think the beginning of next year will be a good time to upgrade.

Cheers!!

I'd wait till the end of this year beginning of next - SP1 of Windows Vista released; drivers will be more mature, new processors from Intel etc. etc. Yes, its abit of a wait but atleast if you purchase it then its going to atleast last 3 years rather than buying something now and regreting it later.

i think i'm reading that wrong. sp1 beta will be released to msdn once it's publicly released? if this is an august preview doesn't that mean sp1 beta must be coming in august as well?

Not necessarily.

It could go either way, but it wouldn't make since for them to release something that nobody could use. So it actually leans more towards a possible release of the Vista SP1 beta in August. Maybe both would be released the same day?

Read more into the article before shouting out an answer.

[edit] nevermind, it does require a new videocard. I only recently bought a Dx10 card :P oh well I figure I'm probally fairly safe for now, since there isn't much Dx10 games out, probally be some time before Dx10.1 and games that use it come out.

Yeah, you'd need a new video card that can do the new Shader Model 4.1. DX10 is Shader Model 4.0. But they can be installed Side-by-Side, something you couldn't do before with DX9 and older.

What the heck does that have to do with this article?

every time something new comes out (new version of Windows, new version of DirectX), Creative Labs doesn't bother updating the drivers or software for existing products - they instead create new products and tell customers to buy the new products in order to get support.

Creative Labs has shown time and time again that they don't support their products, so having a new version of DirectX means they will have one more thing not to support with the current products.

I'm still waiting for 4 speaker/DirectSound3D WDM drivers for my CT4700 based Sound Blaster PCI128. it's been 8 years, and they have yet to release drivers for it.

they released VXD drivers for it that supported 4 speaker/DirectSound 3D under DirectX 5/6, but their WDM drivers only support standard 2 speaker audio.

As much as I agree with you that creative are crap... and they should have updated the drivers for that card before... 8 years! They won't do that now will they. If they were going to do it, at all, they would have done it already. Perhaps it's time to let it go.

i wouldn't update drivers for an 8 year old card either.

either buy a new card or stop complaining, if after 8 years you still haven't learned to perhaps not buy creative products anymore then thats your problem.

the adage, "trick me once shame on you, trick me twice shame on me" comes to mind.

well, the card wasn't 8 years when they stopped supporting it.

i purchased it brand new in 1998, and by 1999 it was forgotten. Creative Labs recommended people buy an SB Live! at the time. and of course all those who purchased an SB Live! were forgotten when the SB Audigy came out, and so on.

i ended up purchasing a CMedia 8738 sound card. even though it was basically AC'97 audio on a PCI card, the company made WDM drivers that worked with all 4 speakers.

from that i went to a Turtle Beach Santa Cruz. drivers havent been updated for it in years, but they at least provided WDM drivers.

now i've been using my nForce3 system's onboard audio, Realtek ALC650 i believe. 6 speaker support. they have good support even for 64-bit Vista.

I see it as another nail in the coffin of hardware accelerated audio (which is controlled by "Creative" Labs). With multi-core processors CPU utilization for audio is insignificant.
