Key new features and updates available in Unreal Engine 4.22 include:

Real-Time ray tracing (Early Access): Selectively ray trace just the passes that benefit from it, to achieve subtle, accurate effects that contribute to the realism of your scene, like true reflections and refractions, soft area shadows, and ambient occlusion–at blazingly fast speeds. Watch the 90-second “Troll” short film to view unprecedented cinematic-quality lighting using UE 4.22 ray tracing features.

Simultaneous multi-user editing (Early Access): Collaborative editing allows multiple developers to simultaneously make and view changes to the same Unreal Engine project, facilitating effective collaboration that eliminates bottlenecks and inspires creativity.

Faster mesh drawing: UE 4.22’s rendering code refactor significantly improves mesh drawing performance, with more aggressive caching of drawing information for static scene elements, and automatic instancing to merge draw calls where possible.
