Also a qustion if i may. 
Alot of talk on the forum of late related to NVIDIA Gameworks and we seen forks for WaveWorks intregration and apperantly VXGI in January.
And i noticed on NVIDIA Gamewors Page that Flex is upcoming for UE 4.
Its been hard to find any real confirmation on this so am wondering.
[Q] Are these all solutions that be supported out of the box with the coming versions of UE 4?
[Q] And are you able to talk a litle off what is actualy is getting implemented over the next couple of months?
Cheers!
