UPD: Microsoft released Win 8 Consumer preview release!!!

Also AMD released NEW WIN 8 drivers with some very VERY interesting (for US (3D USERS)) features:

Feature highlights of the AMD Catalyst™ driver for the Windows® 8 Consumer Preview:
Full WDDM 1.2
Highlights include:
Native Stereo 3D support: Windows 8 will natively support Stereo 3D for full-screen and windowed gaming, and video applications
Unified Video API – Video playback is now integrated within the DirectX® 11 API; enabling simultaneous high quality Video and 3D content, and the potential for enhanced video transcoding performance
Optimized screen rotation
improved sleep / resume performance
Optimized Power Consumption

So Im very excited about this, intertesting Tridef ignition works with that?

Without being able to confirm it:
I think the "old" way Tridef etc. currently use will still work (we're talking windows here, and thus it is backwards compatible). But ther could be a possibility to unify the middle wares to work via the new Windows/DirectX interface so Tridef and DDD could work with 3DVision if nvidia also includes Win8-style 3D support in their drivers.

Then microsoft will release their own sets of 3d-hardware which is supported only by win8 (and win8 only supports them of course...). I'm just joking but in these times things tend to go this direction. Are everybody sure native 3d in an op-system is good?

Probably it will be the same thing as with DX10: Not for earlier systems. But i suspect that the will give DX11.1 to Win 7 because they know that win 8 will fail horribly...
Own set of hardware won't be likely... that would mean to pull of a complete new product category and we havn't seen any hype about it. Also Microsoft hasn't propagated native 3D support as some kind of killer-feature so i doubt the'll monetize it much.

This would only kill 3rd party drivers if game developers all embraced it and coded native support, which is probably not happening any time soon (though I wish). Even the few games that have native support, it was because of partnerships with the GPU makers (mostly Nvidia). This wouldn't be possible unless Microsoft was putting some muscle behind this. And there will still need to be drivers to support specific display setups, especially weird stuff like dual projector, planar mirror, etc.

It would be nice if DDD and iz3d continue development and if game developers want to add 3d to their games to just add a side by side option regardless of what hardware the game detects or doesn't at least minimally. Most 3d monitors have sbs. Like Crysis 2

i also read somewhere they said 3D natively in Windows 8, then it specified it required middleware to use it.... I'm like what? hahaha I'll pass... Until someone actually uses Windows 8 and confirms how it works.... altho I have seen posts about how to get DDD to work in Windows 8 by googling.... again a driver related thing the hardware companies are supposed to work on.... I'm just glad my CF HD7970s work in 3D in Windows 7 unlike the odd game that gets worse performance in CF and EYEfinity(5760x1080) but i must say the new 12.11 drivers rock my CF setup!!!!!

Direct3D 11.1 SDK documentation has been released back in September 2011 and I assume no major changes have been made since.

So yes, it's just a quad-buffer interface much like AMD HD3D, which requires either your game/application or middleware "stereo driver" to implement actual rendering into each L/R view.

Far from a developer-friendly solution when you pass a flag and the Direct3D runtime takes care of the rest.
