gsdx uses dx10?!
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! not to mention, there are very few people with dx11 cards out there...
