Doom Eternal 120Hz Performance Mode: How id Software Maximized Series X Hardware

Few engines in the history of game development can match the raw engineering prowess of id Software's id Tech 7. With the next-gen patch for DOOM Eternal, the Dallas studio pushed Xbox Series X hardware to its absolute limit, delivering a blistering 120Hz mode that completely redefines console responsiveness.

Halving Input Latency at 120 Frames Per Second

In a hyper-speed arena shooter like DOOM Eternal, where surviving on Ultra-Nightmare difficulty requires quick-swapping between the Super Shotgun, Ballista, and Precision Bolt in fractions of a second, framerate is not just visual flair—it is gameplay responsiveness.

Running at 120 FPS cuts total controller input latency from approximately 68 milliseconds down to a razor-sharp 32 milliseconds on compatible HDMI 2.1 displays with VRR enabled.

• Dynamic 1800p at 120Hz: Series X maintains exceptional image clarity while doubling the temporal sample rate.
• Ray Tracing Mode: Enables real-time ray-traced reflections across glass, metal, and blood-soaked metal surfaces at 60 FPS.
• HDMI 2.1 & VRR Support: Eliminates screen tearing completely during chaotic Marauder and Tyrant battles.

DOOM Eternal Xbox Series X Display Modes Breakdown

Players can choose between three distinct visual configurations in the video settings menu:

“Our engine is built around speed. When you give players 120 frames per second on a home console, you unlock their true mechanical potential as the Slayer.”

Why 120Hz is the Ultimate Way to Play

Tracking flying Cacodemons, quick-hooking past Baron fireballs, and landing sniper shots on Arachnotron turrets feels telepathic at 120Hz. Once you experience the tactile smoothness of id Tech 7 at 120 FPS, playing at 60 feels sluggish by comparison.

Play on Xbox Game Pass

DOOM Eternal and its expansions, The Ancient Gods Part 1 and Part 2, are available with Xbox Game Pass on Console, PC, and Cloud. Plug into a 120Hz display and rip and tear.
