NVIDIA GameWorks Integration

Only people with a UE4 license can access UE4 source. The source at /NvPhysX/UnrealEngine is a fork of the Unreal source and is therefore controlled by Epic and subject to their license, just like the source at /EpicGames/UnrealEngine. Previously required a paid subscription, but as I read it, the big announcement today means that people only have to register and agree to the licensing terms, there is no more monthly subscription fee for UE4.
