Are rumors true about Vista SP1?

[deerhunter716]

That the 8800GTX will no longer work for DX10.1 and SP1?

 

[SickBeast]

No.

I heard that DX10.1 was dating that hot chick from the transformers movie.

If a game is 10.1 compliant, a few features that are locked just won't work with a 8800GTX. The 8800GTX will still work minus those features that it does not support.

This is definately the case, and much like every time directx was updated in the past, youll never run into a scenario where a less than a year old flagship card wont run a game because of API issues. Developers build in layers of compatibility into their game engines to prevent these types of issues.

Actually both 2900XT and 8800GTX support all major feature of DX10.1

You will just need a driver update to enable it or they can just not support it

AFAIK The 8800GTX does not support tesselation.

If you have sources saying different, please share

Is that even a DX10.1 feature?

All i heard was DX10.1 makes 4xAA MSAA a must for all games, and also something about AF.

I heard SP1 is cold with solution.

So far, tessellation isn't mentioned as a DX10.1 feature.

Direct3D 10.1 Tech Preview

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.

* TextureCube Arrays which are dynamically indexable in shader code.
* An updated shader model (shader model 4.1).
* The ability to select the MSAA sample pattern for a resource from a palette of patterns, and retrieve the corresponding sample positions.
* The ability to render to block-compressed textures.
* More flexibility with respect to copying of resources.
* Support for blending on all unorm and snorm formats.

This tech preview provides an early look at these features and the handful of new APIs that support them. 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.

Microsoft DirectX SDK (August 2007)

It is possible, however, that they could add it to one of the upcoming scheduled updates.

What's New in the August 2007 DirectX SDK

This version of the DirectX SDK contains the following new features, tools, and documentation.

New Release Schedule

Starting after the August 2007 release of the DirectX SDK, Microsoft will deliver future updates four times per year. The next five releases now planned for delivery are:

* August 2007
* November 2007 (instead of October and December)
* March 2008 (instead of February and April)
* June 2008
* August 2008

This delivery schedule will continue our strong track record of regularly releasing new features and tools, while allowing for longer technology development cycles.

Yes, and you'll have to walk, skateboard, or ride a bicycle for transportation, because the internal combustion engine will cease to function as well. Something about D3D10.1 changing the laws of physics governing the internal combustion process as we know it.

Bad day, that will be. I'm pretty sure I'll just commit suicide the day D3D10.1 is released, no sense in going on as life will be unbearable with "just" D3D10. I almost ended the madness when SM3.0 was introduced with DX9.0C, since my DX9.0B graphics card was "only" SM2.0.

 

[deerhunter716]

hehe, thanks all for the info.

DirectX - rather Direct3D has something called compatibility mode (the reference renderer). If the specific function isn't available or exposed by hardware, D3D has the option to drop to software emulation of that particular function. Hence, all cards can "support" a given level of Direct3D. That's not to say that the vendor pipeline will ever enable the software layer due to significant performance issues.

The 8800 may not be capable of supporting all the features of DX10.1, but that does not mean in any way that a given title won't work on an 8800. It would truly take an idiotic company to NOT include multiple rendering pipelines in their game, one that supports D3D9, D3D10, D3D10.1 and/or OpenGL for example. After all, if you want your title to SELL well, you need to market for XP, which there is no DX10 for...

I'd imagine that for most of that stuff, they would just add driver support for the G80 to handle it, and in the worst case it would just be substantially slower in those few features than newer hardware. Probably not anything to worry about in real-world usage.
