Changeling:
Let me turn this around for you; why should I use DirectX? It is only supported on windows, it has an awful record of backward compatibility (case in point: FF7) and the documentation ranges anywhere from lacking to non-existant. Now of course I would never switch to DirectX anyway since that's a lot of work for little or no benefit, but if I were, what exactly would I gain from that?
AlbusJC:
What? I don't see how you could make that connection but anyway the answer is no, nothing you do to a texture can cause that problem.
Well I can think of one
. Just one though don't get you hopes up yet DX lovers. I for one found immense plugin documentation as well as countless ways to filter
only the backgrounds and leave out the 3D. As well as free SDK and audio plugins found...
http://en.wikipedia.org/wiki/DirectX_pluginA Quote from wiki...
"Until about 2005, another functional difference between the APIs was the way they handled rendering to textures: the Direct3D method (SetRenderTarget()) is convenient, while previous versions of OpenGL required the manipulation of P-buffers (pixel buffers). This was cumbersome and risky: if the programmer's codepath was different from that anticipated by the driver manufacturer, the code would have fallen back to software rendering, causing a substantial performance drop. However, widespread support for the "frame buffer objects" extension, which provided an OpenGL equivalent of the Direct3D method, successfully addressed this shortcoming, and the "render target" feature of OpenGL brought OpenGL up to par with Direct3D in this respect."
That would explain why Aali's driver performs poorly FPS wise for some. As I don't know if Aali's driver uses the "render target" feature.
Although they are equal on almost all levels some of the new features of DX11 would be nice to have. I do also want to note as you already know the impossible overwhelming amount of PC users in the market...My take DX=More power; OpenGL=More Flexibility.
it has an awful record of backward compatibility
Those days may be behind us we can only hope still is not looking good...
