hihi! juz wondering wat r the signifcant differences between using render to surface and render target when doing a render to texture?? so far i have been using render to surfaces for abt >128 passes for the pixel shaders, i noticed that offscreen rendering via render to surfaces will incur a slight performance penalty as well. i know we can create textures, then take that surface ptr out and append to either render to surface or render target. i am not referring to MRTs. seems like we could simply "toggle" between these rendertargets, instead of using render to surfaces, and yet acheiving the objective of rendering to a texture... can it? thx!
