Modern Warfare 4 Beta Launches With Cross-Platform Stress Test

Developer teams are issuing rapid patches to fix PC input and performance problems as Switch 2 previews show a native build that favors frame rate over resolution.

Overview

  • The multi‑week beta began in an Early Access window for pre‑orders on Friday, August 21, and will open to all players in a second weekend starting August 28.
  • For the first time in a Call of Duty beta, players can play a full single‑player mission called 'Entrenched' alongside core multiplayer modes and maps.
  • Weekend One limits progression to levels 1–20 and awards five cosmetic beta rewards that carry into the full game, with Weekend Two raising the cap to 30 and unlocking three more rewards plus Warzone Resurgence content.
  • Hands‑on Switch 2 footage—built natively by Digital Legends—generally targets 60 frames per second but makes visible compromises in resolution, draw distance and occasional artifacting.
  • PC players reported mouse input lag, performance problems and setup friction from TPM 2.0/Secure Boot requirements, and Beenox and Infinity Ward have promised near‑term patches and tuning during the beta.
