I quote an article about this setting:

The Surface Format Optimization checkbox allows improved performance in selected games that use 16-bit floating point surfaces for HDR rendering. It is designed to have no discernable effect on image quality,.
Sounds like a reviewer quoting from the supplied AMD PR materials to me.

From my experience, the check box has no effect on the way AMD's drivers handle FP16 at this point. I'll check again when the 10.11 drivers are released but 10.10 WHQL and 10.10c don't show any difference when it is toggled.

I've got bits and pieces of testing done for an IQ article and FP16 is one of the first things I tested for when 10.10 came out.
