FPS & performance
Low or unstable frame rates, stutter and input lag, and the settings that actually affect them.
- Low FPS and stuttering in Call of Duty: Modern Warfare 4: how to fix itLow or uneven frame rate in Modern Warfare 4 on PC is a performance problem, not an error code, and Activision has not listed an official FPS bug. Third-party guides commonly suggest letting the game finish shader preloading before a match, then updating your GPU driver and turning on upscaling if your card supports it.
- Games stutter or have uneven frame times on Windows 11: how to fix itStutter means frames arrive unevenly, so a game can feel choppy even when the FPS counter looks fine. Windows 11 has no error code for it, and the cause varies by setup. Start with driver and Windows updates, close background apps, then test HAGS and Memory Integrity one at a time.
