i understand some of its issues but that also depends on the type of style of game you are after, for instance our current project works great on msaa and forward withbgreqt performance but as soon as we tried taa it felt like we had to redo all the textures and shaders and some of the smaller geos all over again to compensate for blur and ghosting. Give ua msaa in deferred since at the moment we have no other choice and let us choose. And fxaa is worst than taa.
