Wow. Nice interactivity with video materials to boot. UE4 + VXGI does appear to be the frontrunner for full dynamic GI in games.
Has anyone tried VXGI on AMD? Hard to find resources whether it will work well on AMD (probably not the NvPhysX branch anyway?).
Update: VXGI + HBAO + FLEX + WaveWorks + HairWorks* confirmed working with latest. Have a good week playing with it all!**
*At least with Nvidia demo material etc.
I thought GameWorks would be really slow but Flex, WaveWorks and HairWorks seem to run OK thus far on my GTX660M. HBAO is not too bad. VXGI is quite different, of course. Certainly requires a card to even develop with it.
