Call of Duty: Modern Warfare 4's Nintendo Switch 2 release has drawn close technical scrutiny from Digital Foundry, which lauds the port's overall optimisation while calling out serious input-latency concerns that particularly affect multiplayer play.
The Modern Warfare series is developed by Infinity Ward and published by Activision; this analysis focuses on how the Switch 2 build compares to current-gen console performance.
Digital Foundry’s assessment notes that once missions begin the Switch 2 version maintains consistent frame pacing and avoids stutters or slowdowns during key campaign moments.
The report highlights that core visual systems carry over well to the platform: interactive smoke, destructible glass, wall-projected video elements and high NPC densities remain present in busy urban scenes, delivering much of the series’ intended spectacle on Nintendo’s hardware.
On image quality, Digital Foundry describes two primary anti-aliasing and upscaling pathways: a standard SMAA mode and Nvidia’s DLSS upscaler.
When docked with DLSS active, the game targets a dynamic resolution around 900p, occasionally dropping to roughly 450p during graphically intense sequences such as the Paris vehicle chase.
Native SMAA settings are assessed to cover a similar dynamic range, with peaks approaching a 1080p target.
In handheld mode the build targets a dynamic 720p baseline with dips to about 360p under heavy load, while feature parity with docked play is largely retained aside from output resolution.
The most consequential finding for competitive players is input latency.
Digital Foundry measured multiplayer input lag on Switch 2 at approximately 81 ms in docked mode and 100 ms in handheld (with observed variability between about 83 ms and 125 ms in portable testing).
By comparison, Digital Foundry cites PlayStation 5 input latency at 60 Hz as roughly 49 ms.
The publication concludes that Switch 2 input latency is substantially higher — about 64% greater when docked and roughly double in handheld — creating a meaningful responsiveness gap for multiplayer matches.
These latency tests were performed using the Switch 2 Pro Controller and Sony DualSense wirelessly, reflecting common player setups.
While Digital Foundry praises the port’s optimisation and visual fidelity, it recommends that the elevated input lag be addressed via a software update to bring Switch 2 responsiveness closer to that of other consoles.
