Deferred shading anti-aliasing
<p>Many people note that MSAA does not work with deferred shading. Why is that? It sounds okay in my head.</p>

<p>According to <a href="https://en.wikipedia.org/wiki/Deferred_shading" rel="noreferrer">wikipedia</a>:</p>

<blockquote>
  <p>... due to separating the lighting stage from the geometric stage,
  hardware anti-aliasing does not produce correct results anymore since
  interpolated subsamples would result in nonsensical position, normal,
  and tangent attributes.</p>
</blockquote>

<p>Can you explain that?</p>

<p>What are the other AA alternatives I have?</p>
