and no you cant just "patch" something so that it uses directxXX technology. if its written for directxA, it doesnt use directxB. its like patching a app intended for mac to run on windows. just not that extreme. If you want to use the features that come with dx10 or 11, you have to rewrite the plugin. the games wont look more awesome, but there might be a small speed boost when done properly. other than that, not necessary!
Gsdx actually can use DX10 and DX11 to render PS2 game, it is also faster and more stable than the DX9 version of Gsdx. The PS2 doesn't use DirectX, it uses an in house derivative of OpenGL. With emulation it is possible to render and output graphics using the DirectX API.
:Edit: Eh, misunderstood you..
Technically it wouldn't require a rewrite to include DX10 or DX11 support. Support for a DX10 or DX11 renderer can be added into the existing plugin, and add a dropdown menu which allows users to choose what renderer to use. It's not easy to do and requires a bit of work, but it wouldn't require an entire rewrite of the plugin.
Does anyone know if Dolphin takes advantage of the SSSE3 and SSE4 instruction sets like Pcsx2 does or does Dolphin only support SSE2? If Dolphin lacks SSSE3 and SSE4 support, would adding support for these instruction sets into the existing graphics plugins offer a slight performance advantage for Dolphin as well?
