To judge how expensive, we use the game's great integrated benchmark that flies through various levels. So all in all, it's a very comprehensive RT implementation that also uses high quality settings in an environment with a lot complex vegetation - so we expect that the ray tracing here will be expensive. In practice, DDGI doesn't dramatically change the game's lighting, as the game already uses plenty of static baked lighting, but it still adds to the overall realism of many scenes.įor more information on probe-based global illumination, check out our Tech Focus on the topic. It's a kind of probe-based diffuse global illumination that uses RT to prevent the usual issues probe GI can have. The last RT effect is the most subtle of all: DDGI or Dynamic Diffuse Global Illumination. Normally this sort of caustic effect is faked, so it's rather neat to see a whole new layer of light added to a scene and new shadows as well. What's more interesting is its use with transparent meshes, which range from the obvious (light being coloured after passing through a stained glass window) to the subtle (an added bounce of light and slight chromatic dispersion from light emitted from a lamp's glass housing). Meanwhile, RT caustics enhance the appearance of water, which is something we've seen before on Unreal Engine RT games. The inclusion of this feature also generally improves transparency shading. Translucency adds realistic refraction to transparent objects like bottles, showing a realistically distorted view of the world, or RT reflections on surfaces like car windscreens. It's all very impressive and uncomprising - and of course, this doesn't come cheap.Īs well as RT reflections, the game uses RT translucency and RT caustics.
This is no longer a clean, modern city, and it is key that its reflections actually mirror that.
Finally, all vegetation is captured in these ray tracing reflections every branch, twig, bush, tree and leaf can be seen if you look at a reflected surface.

It even uses full detail textures and objects in its reflections, rather than computationally cheaper but lower resolution assets with worse geometry or materials as we see in most other games.
Similarly, the game takes objects kilometres away into account when generating its reflections.
