We pointed out yesterday that Bethesda’s original grid included some processors that don’t exist. You can see the corrected grid on Bethesda’s website.

Jim Kjellin, MachineGames’ CTO, also explained to The Verge why hardware ray tracing is required even at minimum specs:

Indiana Jones and the Great Circle uses a technique called global illumination to light the environment and characters. Our engine MOTOR, used by MachineGames, uses hardware raytracing to calculate this. While this isn’t what players may typically think of as “ray tracing,” the compatible hardware is required to do this is in a performant, high fidelity way.
