Doom The Dark Ages ray tracing might have killed your frame rate, but at least it saved id 110GB of disk space
id Software has revealed that implementing real-time ray tracing in Doom: The Dark Ages, instead of pre-baked global illumination, significantly reduced potential disk space requirements and development time. While this decision necessitates ray tracing-capable hardware and can impact frame rates, it allows for more complex environments and faster iteration during development.
