Nvidia VRworks was held at Games Solutions Centre on the 6th May which promotes the use of its SDK on the unreal engine platform which claims to BOOST performance by up to 100%.
Its not really open to download on the internet unless you contact them but they are very open to it. Nvidia is supportive of building the VR ecosystem, partly because VR demands more of graphic cards…. “7X more!” claims Nvidia.
A HTC Vive demo was also available showing Everest VR demo after the talk which has good graphics but its just a short demo without much playability. Try the real games instead.
