A new version of the Unreal Engine just got released (4.16) full of new features and improvements. As you may recall, UE is free for most to play with. The release notes are extensive, along with a cool video showcasing some of these: low-level clothing simulation, image-based (FFT) convolution for bloom, distance field lighting optimizations, games on Nintendo Switch, and physics simulation in VR mode.
