Hello. I just want to know if windows 8 is going to support dx 12 or only win 10 will support dx 12. So will dx 12 be supported by win 8.1 and radeon r9 280x?

I have read that DirectX 12 will be exclusive to Windows 10. So no, you probably won't be able use it on Windows 8, unless they change that.

The good news is that the upgrade to Windows 10 is supposed to be free for Windows 8.1 users if they upgrade within the first year. So my recommendation would be to upgrade.

As for the 280X, I don't know. I've heard that DX12 will come to all Nvidia GTX cards all the way back to the GTX 400 series (could be wrong on that). But I don't know if they're going to try to push Mantle on AMD cards or try DX12.

Finally, with Microsoft’s announcement of their Windows 10 plans last month, Microsoft is also finally clarifying their plans for the deployment of DirectX 12. Because DirectX 12 and WDDM 2.0 are tied at the hip, and by extension tied to Windows 10, DirectX 12 will only be available on Windows 10. Windows 8/8.1 and Windows 7 will not be receiving DirectX 12 support.

Backporting DirectX 12 to earlier OSes would require backporting WDDM 2.0 as well, which brings with it several issues due to the fact that WDDM 2.0 is a kernel component. Microsoft would either have to compromise on WDDM 2.0 features in order to make it work on these older kernels, or alternatively would have to more radically overhaul these kernels to accommodate the full WDDM 2.0 feature set, the latter of which is a significant engineering task and carries a significant risk of breaking earlier Windows installations. Microsoft has already tried this once before in backporting parts of Direct3D 11.1 and WDDM 1.2 to Windows 7, only to discover that even that smaller-scale project had compatibility problems. A backport of DirectX 12 would in turn be even more problematic.

The bright side of all of this is that with Microsoft’s plans to offer Windows 10 as a free upgrade for Windows 7/8/8.1 users, the issue is largely rendered moot. Though DirectX 12 isn’t being backported, Windows users will instead be able to jump forward for free, so unlike Windows 8 this will not require spending money on a new OS just to gain access to the latest version of DirectX. This in turn is consistent with Microsoft’s overall plans to bring all Windows users up to Windows 10 rather than letting the market get fragmented among different Windows versions (and risk repeating another XP), so the revelation that DirectX 12 will not get backported has largely been expected since Microsoft’s Windows 10 announcement.

DirectX 12 and backwards compatibility with the older OS's (7/8.x) is too much work.
 
u get a free upgrade to windows 10 plus they skipped windows 9 the bad OS.....(pun intended.. iknow why it's called W10 instead of W9 )

so u don't have to worry about it

DX12 recuriments is a for nvidia is a gtx 4XX and above fermi cards i think?

and AMD GCN and above

DX12.1 support ATM is exclusive to nvidia GTX9XX series
 
The fun theory is that there are applications that do the following:

So previously we had two Windows OS kernels. Win9x and Windows NT. Applications that were written for both would query the windows version in a particular part of the registry. But only the first character. If it returned a 9 it would run the 9x installation.

Sort of related to the "You are not in Chicago any more" which was an error message that would appear when you tried to install a 9x application on an NT platform.

But pretty sure it is just marketing, because Microsoft has all of kinds of tools (Shims, particularly version lie and other compatbility modes)
 


Probably. This from a couple of months ago:

The ISO probably indicates you'll be able to do a clean install.
However, let's wait a few weeks for more info to emanate from the mouth of Microsoft.
 


ok. please please please let me know when you find out. I want dx12 and win 10 is exclusive to it. I will only do a clean install.
