Minecraft is getting a free update that brings much-improved lighting and color to the game’s blocky graphics using real-time ray tracing running on Nvidia GeForce RTX graphics hardware. The new look is a dramatic change in the atmospherics of the game, and manages to be eerily realistic while retaining Minecraft’s pixelated charm.

The ray tracing tech will be available via a free update to the game on Windows 10 PCs, but it’ll only be accessible to players using an Nvidia GeForce RTX GPU, since that’s the only graphics hardware on the market that currently supports playing games with real-time ray tracing active.
