But I understand that the final image gets a little blurry and the textures washed...
Actually it doesn't. If you use Wide or Narrow tent it gets noticeably blury. But with MLAA, i couldn't notice any blur on textures or overall image. So even if there is some blur i can't see it. Doing side by side image comparison, but that's just for technical standpoint, wouldn't prevent me from using MLAA as i'm happy with it's results.
