Is still an? I don’t remember if you can disable WaveWorks with some console parameter. I wasn’t aware of WaveWorks adding a cost unused though and I don’t really have time to investigate it myself now so I put out different branches with and without WaveWorks merge:
(Blast, Flow, HairWorks, HBAO+, TXAA ad VXGI2)
(same as above but with WaveWorks)
