Yes, but the tech has not advanced that much since then. Also the game probably doesn't look twice as good.
Tbh. the game needing 8 cores is the most outrageous of the list, but the ray tracing is a close second, since that could easily be toggleable.
In a doom game ray tracing should not be used for registering hits, since most if not all of the projectiles are visible and fly slower than light.
