NVIDIA GameWorks Integration

You can get that same effect using HairWorks, you just need to play with the settings some more, default settings are not good.

They apparently refactored a lot of the integration for 4.9, check the config options, make sure they are the same between 4.8 and 4.9, so maybe thats why there is a difference in performance.

I would love to and TurfWorks if NVIDIA would me access to do so.

Yes it does.
