Activision’s latest patch for Call of Duty: Modern Warfare 4 Beta reduces mandatory restarts for PC players on Battle.net or Steam and for PS5 users, while Xbox Series X|S and Nintendo Switch 2 models continue to require interruption during updates.
Restarts Cut on PC and PlayStation
After most updates are delivered, players on eligible platforms can hop back into the game without relaunching. A restart remains necessary if an update arrives mid‑session, so the time‑loss is narrowed to brief reboots rather than full delays.
Shader Preloading: A First for Call of Duty
The shift to shader preloading marks Activision’s first industry‑wide implementation for the franchise. By compiling shaders before launch, launch times drop and frame‑rate hiccups during play fade. The improvement also tackles shader‑related performance dips that plagued earlier titles.
Hardware Prerequisites to Maximize Gains
To harness the full benefits of the new system, PC users should enable TPM 2.0 and Secure Boot. Activision also clarified minimum and recommended specs, underscoring a deliberate push toward optimisation.
Why Xbox and Switch Players Still Wait?
The persistent requirement on Xbox Series X|S and Nintendo Switch 2 has fueled frustration among the community, especially given Activision’s partnership with Xbox. While the rest of the platform roster moves forward, these two groups don’t yet share the streamlined update experience.
Beta Launch and User Feedback
Activated around the time the beta was distributed, the new system will allow testers to assess a smoother launch and less disruptive update cadence before the full game roll‑out.
