Digital Foundry Finds Significant Input Lag in Call of Duty: Modern Warfare 4 on Nintendo Switch 2

Digital Foundry Analysis Reveals Input Lag Disparity

Digital Foundry's technical analysis of *Call of Duty: Modern Warfare 4* on Nintendo Switch 2 indicates that the port suffers from substantially higher input latency compared to other platforms, creating a measurable competitive disadvantage in multiplayer modes. The findings, reported by IGN, show that the Switch 2 version exhibits input lag roughly double that of the PlayStation 5 version when both target 60 frames per second.

Performance Details

• Docked mode: Average input latency of 81 milliseconds.
• Portable mode: Average input latency of 100 milliseconds, with a observed range of 83 ms to 125 ms.
• PlayStation 5 (60 fps baseline): 49.1 milliseconds.

According to Digital Foundry, the portable mode latency is "actually deleterious to performance," meaning players' actions register noticeably later than on competing hardware. Variable Refresh Rate (VRR) support on compatible displays can mitigate frame-rate drops, but does not eliminate the underlying input delay. The multiplayer mode generally maintains its 60 fps target, though certain scenarios — such as viewing through a riot shield's transparent visor — can cause frame-rate dips.

Campaign Experience

Outside of competitive multiplayer, the campaign runs at a locked 30 fps and 4K resolution while docked. IGN's Simon Cardy noted that while textures and character models are visibly simplified — describing them as having a "plasticine" appearance — the gameplay remains smooth and feels responsive enough for a single-player experience. The visual downgrade is consistent with the Switch 2's reduced graphical horsepower relative to PC, PS5, and Xbox Series X.

Context: Microsoft's Commitment to Nintendo

The arrival of *Modern Warfare 4* on a Nintendo console marks the first *Call of Duty* release on Nintendo hardware since *Call of Duty: Ghosts* in 2013. This release stems from a 10-year agreement Microsoft made to bring *Call of Duty* to Nintendo platforms as part of its regulatory concessions during the $69 billion acquisition of Activision Blizzard. Then-Xbox head Phil Spencer stated in December 2022 that Microsoft was "committed to helping bring more games to more people — however they choose to play."

Practical Implications for Players

• Competitive multiplayer: Players on Switch 2 face a tangible responsiveness disadvantage; crossplay matchmaking may place them against opponents with lower input latency.
• Portable play: The highest latency occurs in handheld mode, making it the least suitable for competitive matches.
• Campaign and casual modes: The 30 fps campaign is playable and enjoyable for those without access to other platforms.
• Verification: Players can review Digital Foundry's full video analysis on their YouTube channel and IGN's written report for methodology details. No official patch or mitigation has been announced by Activision or Nintendo as of publication.
