It shows that dynamic resolution isn't the end all solution.
DF measured resolutions from 4224x2376 all the way down to 1496x842, or a factor 8 difference, while still dropping frames. DF cites higher geometry detail and higher fixed buffers for depth of field, color correction and bloom as the reason for the bigger drops. (2160p vs 1440p buffers on pro)
This only proves that a pro patch or X patch involves a lot more than simply turning up a few dials. The software still needs to be optimized to run well across the board.
