Unreal Engine is used by over 7.5 million developers worldwide, from those working on innovative indie games, to many of the world’s biggest franchises (see a list of games here).

Now, ray tracing development tools are available to all professional, amateur and enthusiast developers worldwide with the public release of Unreal Engine 4.22, making ray tracing more accessible and easier to implement, accelerating adoption. And that of course means more games with fabulous, immersive, real-time ray-traced visuals.

To demonstrate the power and possibilities of Unreal Engine 4.22 and its new ray tracing tools, Epic Games, Goodbye Kansas and Deep Forest Films went to GDC 2019 and demonstrated "Troll", a ray-traced demo-stroke-film that ran in real-time on a GeForce RTX 2080 Ti.

Offering a glimpse of what developers and creators can do with ray tracing running on GeForce RTX GPUs, the demo marks an unprecedented level of cinematic-quality lighting, with complex soft shadows and reflections.
