From what I've read, one of the main benefits of LPP over traditional deferred is that it supports hardware MSAA. Other benefits include: different approach to shader permutations, smaller GBuffer size. Cons include: extra CPU/GPU cost for rendering more geometry passes. For me, the lack of MSAA on (DX9 level) deferred renderers is one of their main problems, so 'upgrading' to LPP seems like a good idea. Now, if you were given an LPP renderer that had no anti-aliasing support whatsoever, would you be a bit confused / disappointed, or would you still use it anyway for the other benefits?
