Digital Foundry Finds High Input Lag on Modern Warfare 4 for Switch 2

Measured docked and handheld controller delays of roughly 81ms and 100ms create a clear competitive gap that will likely need software fixes.

Overview

  • Digital Foundry’s technical analysis, published Friday, measured multiplayer input latency on Switch 2 at about 81ms docked and 100ms handheld versus roughly 49ms on PS5, a difference that can hinder aiming and reaction in online matches.
  • The Switch 2 build meets stated frame‑rate targets—30 FPS for campaign, 60 FPS for multiplayer and ~40 FPS in DMZ on 120Hz displays—but multiplayer sometimes dips into the high‑40s and 50s FPS, causing intermittent performance drops.
  • Key game systems such as interactive smoke, destructible glass and high NPC counts are preserved on Switch 2 while some effects like bump mapping, screen‑space reflections and player self‑shadows are reduced or removed to save performance.
  • Image quality relies on two upscaling paths: Nvidia’s DLSS option targets a dynamic 900p docked baseline (falling to 450p in heavy scenes) and SMAA can push toward 1080p; handheld uses a dynamic 720p baseline with drops to 360p.
  • Developers have pushed early patches and a large Switch 2 update, the smaller ~88GB install reduces storage pressure versus PS5, and further software tuning will be needed to close the input‑lag gap and improve competitive parity for players.
