NVIDIA GameWorks Integration

Question about GPU and NvCloth

Hi, I saw in the 4.17 Release notes that

as been added to the engine (https://www.unrealengine/en-US/blog/unreal-engine-4-17-released) searching for that , I only found a older 4.16 preview build thread where a UE4 dev said

(https://forums.unrealengine/showthread.php?142071-Unreal-Engine-4-16-Preview/page6&styleid=6) So adds support for pre-GRB GPU support? And now, the next step would be to ask Nvidia to release GPU dll libraries that we can drop in and get GPU acceleration? Also, the mainline UE4 is being moved from APEX Clothing to NvCloth and in the release note of NvCloth, it is mentioned that it supports “Windows (CPU, CUDA, , RenderCloth)” (.nvidia/gameworks/content/gameworkslibrary//nvCloth/ReleaseNotes/index.html) anyone know which version is integrated in UE4 CPU, CUDA or? And I have no idea what is RenderCloth. Thank you
