Call of Duty optimizer & FPS booster for PC

Modern Call of Duty games, Modern Warfare 4 and Warzone included, have dozens of graphics options. A few of them (shadows, volumetrics, ambient occlusion) cost most of the FPS.
What EMP Tweaks does for Call of Duty
- Tweak All: Windows, network, timer and GPU tweaks that help every game, checked change by change.
- Real FPS: average FPS, 1% lows and frame times measured in Call of Duty, before and after.
- Overlay & crosshair: FPS / CPU / GPU overlay and a crosshair overlay as a separate window. Nothing is injected into the game.
- Reset: one button puts everything back the way it was.
Game settings, written for you
Pick Off, Auto, Low, Medium or High for Call of Duty on EMP's Games screen. EMP writes it straight into the game's own settings file while the game is closed and keeps a backup:
Documents\Call of Duty\players
Shadows, effects, post-processing and anti-aliasing follow your pick; VSync and motion blur stay off. Resolution and view distance are never changed. Auto picks the level that fits your graphics card and processor and adjusts it after real FPS sessions.
How it works
- Get a plan and download EMP Tweaks for Windows 10 or 11.
- Log in with your account (Discord or Twitch).
- Press Tweak All, pick your Call of Duty quality on the Games screen and play.
Is it safe?
EMP Tweaks never injects into Call of Duty, never reads or changes its memory and never runs inside the game. It only changes Windows, driver and settings files, the same things you could change by hand.
