We’ve been following the evolution of hardware-accelerated real-time ray tracing for some time now here at Digital Foundry – and one of the most spectacular demos we’ve seen actually took the form of Sonic Ether’s RT shader mod for Minecraft, which brute-forced full path-tracing into the Java version of the classic Mojang title. It’s brilliant stuff, and although slow, it will work on any modern GPU.
But as good as it is, we had to wonder – what kind of improvement would we see with full hardware acceleration? What if Mojang itself incorporated full path tracing into the engine itself? The developer duly delivered at Gamescom 2019 and my colleagues John Linneman and Alex Battaglia played the early code, handing in the extensive deep dive into the demo found on this page.
Similar to our own work with the mod, the developers put together their own custom maps to showcase the effects of full path tracing within the Minecraft engine. In our video, you’ll get to see both of these creations. One of them showcases how the new technology interacts with the existing, older-style textures – which are typically based on 64×64 textures – but the video kicks off with a look at path tracing combined with higher resolution block art, reaching a maximum of 1024×1024.
