E3 2013 - If the tech demo shown by Epic at NVIDIA's press conference is anything to go by, we have a lot to look forward to. Unreal Engine 4 features numerous NVIDIA PhysX features. The tech demo embedded below was first shown at GDC.
At E3, however, Epic focused on some of the NVIDIA features found in the demo. The graphics are seriously impressive and the entire demo is running in real-time from a single GTX Titan.
