I explained on earlier post:
Hairwork samples didn’t work in packaged builds so there was something broken. I don’t have time to investigate it and I’d rather have working build than something that almost works, so I just reverted the HairWorks merge.
WaveWorks which we get from NvPhysX repo is only for NVidia GPUs so I have no interest in merging it. All other tech in that GameWorks repo should run on both Nvidia and AMD GPUs.
