This setup is aimed for maximum energy-efficiency. This means that it produces less shares then normal usage in absolute values, but is much more energy-efficient, which in fact may give even more profitability. Moreover, mining on default settings is actually even unprofitable for me because of expenses on electritity, despite bigger hash-rates.
Main point here is undervolting the GPU in MSI Afterburner. In this setup, clock speed is capped at 1400 MHz at 743mV (see numerous guides on Internet for how to do it).
Normal setup: 380W, 600 KH/W.
This setup: 275W, 966 KH/W.
Note that at least in my case, this algo runs simultaneously with KHeavyHash, so despite this exact algo gets boost in hash-rate, the latter works slower.
Less power consumtion of GPU also leads to less power consumtion of a cooling system, which also increases power-efficiency indirectly.
