Question about graphic card & about directx

[Skoshi Tiger]

CoD uses DirectX 10 features in windows Vista and Windows 7 and DirectX 9 in Windows XP.

Because DirectX10 is a subset of DirectX11 if your running Windows 7 or vista with DirectX 11 you just use DirectX11. When the developers decide to implement the DirectX11 only features you will need a DirectX 11 graphics card to access those features.


from Wikipedia
"Direct3D 11 runs on Windows Vista and Windows 7. It will run on future Windows operating systems as well. Parts of the new API such as multi-threaded resource handling can be supported on Direct3D 9/10/10.1-class hardware. Hardware tessellation and Shader Model 5.0 require Direct3D 11 supporting hardware.[32] Microsoft has since released the Direct3D 11 Technical Preview.[33] Direct3D 11 is a strict superset of Direct3D 10.1 — all hardware and API features of version 10.1 are retained, and new features are added only when necessary for exposing new functionality. This helps to keep backwards compatibility with previous versions of DirectX."
Cheers!

Turned another side, would the game look nicer (recent amazing visual effects) while changing from (for example) Nvidia 260 to 5xx serie which - as far as I understand - does support a feature rich set of visual effects on top of the old ones.

Thanks

The game gives dx10_0 in the conf file. try to change that for 10.1? Won't work

"Because DirectX10 is a subset of DirectX11 if your running Windows 7..."

Really? I was talking about what you typed, not what you quoted (just noting what I thought was an unintentional discrepency).

No what I said is logically(and mathematically) correct. You are either miss-reading it or are trolling.

IF DirectX11 is a Superset of DirectX 10.1 THEN DirectX 10.1 MUST logically be a SubsSet of DirectX11.

For your argument in this case to be correct you must be able to list one feature of DirectX10.1 that is not in DirectX11.

You are correct - I made a mistake because I was taking chronological order into account and I got my terms wrong. My bad m8
