Path tracing kneecaps your graphics card’s performance, though Nvidia’s wonderful DLSS 2.0 technology scrapes a lot of it back. That said, glorious visuals like this don’t come free. It’s gorgeous stuff, and it makes Minecraft feel much more vibrant. Alcoves down there include colored lights inside, and you’re seeing that reflected on that roof, like you would in real life. In the second one, pay attention not only to the light streaming in from overhead, but also the different hues on the roof farther down the hall. These additional scenes from Color, Light, & Shadow show a stunning combination of realistic lighting sources and reflective surfaces. The tiny room’s mirrored walls look spectacular with RTX On, but just like basic grey slabs with the technology disabled, as base Minecraft doesn’t support reflections like this. This room from Color, Light, & Shadow-which is essentially a ray tracing tech demo-reveals how striking reflections can be using the new materials. Hybrid ray tracing is strenuous full-on path tracing hits hard. I spent time exploring them to show some examples of Minecraft’s ray tracing in action, and to get a gauge for the technology’s performance impact. You can find each of the free maps in Minecraft’s Marketplace by searching for “ray tracing.” The official worlds each list Nvidia as the creator in the store.
These new materials make the game feel much more alive and natural, but requiring them means you can’t simply turn on RTX in your existing Minecraft worlds. Ray traced worlds support materials with not one, not two, but four additional states: Metallic, normal, emissive, and roughness. In the standard version of the game, textures have only two material states: Color and opacity.
The Minecraft beta adds “physically based materials” that react to the realistic ray-cast lighting. Look at how the pink and yellow hues from the colored blocks reflect off the marble stairs. Heck, you can even see colors reflected off other solid surfaces, as shown below.
