Overview
- Activision has added a Shader Preloading system to the Modern Warfare 4 Beta that prepares and compiles shaders before you launch the game to reduce lengthy first‑time waits and in‑game stutter.
- The preloading runs in the background after install and after major updates, can be disabled or canceled, and will resume progress when you next load the game.
- Activision and the developers say the process is CPU‑dependent but tuned to use minimal resources so it should not severely impact other tasks while it runs.
- Beta testers will see platform differences: PC (Battle.net and Steam) and PlayStation 5 largely avoid restart prompts for most updates in the Beta, while Xbox Series X|S and Nintendo Switch 2 still require restarts during the test.
- The Beta rollout arrives alongside published minimum and recommended PC specs and aims to surface hardware edge cases so Infinity Ward and Beenox can refine the system before full release, which could reduce a common pain point across modern PC games.
