    Re: Some OpenGL 3.2 and Directx 11 questions

    There are additional compute shaders models (4.x) for Direct3D 10/10.1 level hardware. But you would need new drivers and the hardware needs to support all features of this new models.

    Re: Separate sampler state from texture state

    Yes you can. The actual syntax for a sample operation is:

    DXGI_FORMAT Object.Sample( sampler_state S, floatx Location [, int Offset]);

    You can combine every sampler state object with every...

    Re: OpenGL 3.2 vs. Direct X 11

    DX11 support older hardware, too. You just canít use all features. There are six well defined feature levels for different hardware.

  5. Re: OpenGL 3.2 support in new nVidia linux beta dr

    Nvidia has some new OEM hardware that supports 10.1 (G210 & GT210). Beside of these the Direct3D 10.1feature level says all or nothing. Therefore itís quite possible that a chip that doesnít support...

    It isnít such a big problem to use both APIs in one program. But XP support will drooped one day and for Direct3D 9 hardware we will get 10 Level 9 in Direct3D 11. So we are back to one Direct3D API...

    Re: DirectX 11 preview available, impact on OpenGL?

    While I agree that most game developers will stay with Direct3D 9 more and more add an additional Direct3D 10 path. There are even some titles in development that will require Direct3D 10.

    Microsoft offers an additional software device for Direct3D 9 (not the ref rast). But as it is not part of the SDK this is not well known.
