Steam does not attach an official resolution, preset, or frame-rate target to either tier. “Recommended” therefore should not be read as a guarantee of 4K, maximum settings, or a fixed frame rate.
Halo Support lists the actual download as 70 GB or less, while Steam asks for 100 GB available space. Those numbers measure different things: transfer size versus installation headroom. Use the larger Steam value when deciding whether the drive has enough free space.
