I'm talking about your claim of DSR + 32x CSAA.

You weren't doing that on Maxwell because Maxwell does not support CSAA!  The CSAA logic was removed from the ROP's and MFAA added in its place as well as allowing the ROP's to operate more efficiently in Maxwell compared to Kepler.

You can do CSAA on Kepler, but a 780 is very underpowered for DSR to begin with and Kepler doesn't do DSR as effeciently as Maxwell does.

Hmm, I wonder why Maxwell doesn't support CSAA?  That's what Nvidia worked so hard as a new feature with G80 (8800GTX) and brought out 32x CSAA that greatly enhanced DX10+ games on Fermi cards.  I never actually bothered with using CSAA on the Maxwell cards, due to the little time I had them (for bitcoin mining). 

Perhaps CSAA didn't work properly for some games (which was my long-time suspicion from many years ago)?  I actually though it was TR-MSAA (not TR-SSAA) that was sucky, but perhaps it's that DX10+ does not allow for CSAA to be forced on if the games do not specifically support the CSAA feature with DX10/11?
