Oh I should also say that I wasnt at GDC and havent found a good record of nvidia-related GameWorks stuff discussed there (apart from all the raytracing-related stuff). So I dont know if I missed any little details that would be pertinent to debate. eg I know that an updated version of FleX was discussed along with Unity plugin and updated UE4 plugin, but I dont know what was said about the UE4 plugin.
