Call of Duty: Modern Warfare 3, a first-person shooter game developed by Infinity Ward and published by Activision, has been a favorite among gamers since its release. However, some players have encountered issues with the game's performance, specifically with frame rates.

- Half V-Sync (VSync Half Refresh): If your monitor is 90Hz, half is 45. If your monitor is 144Hz and you have a frame rate limiter set to "Half," the engine targets 72 FPS, but if V-Sync engages via a bug, you slide down to 45.
- Background Process Conflicts: Old RGB software (Corsair iCUE, Razer Synapse, Logitech G Hub) sometimes injects DLLs that conflict with the IW 9.0 engine, causing the renderer to stutter-lock at half your refresh rate.
- Windows Power Saving: If your laptop or desktop is accidentally using integrated graphics, 45 FPS is a common thermal/power throttle threshold.
- VRAM Saturation: When your Video RAM fills up, the engine panics and drops to a "safe" framerate floor, often 40-45 FPS.
For many users, especially on Windows 10/11, the game may cap at approximately 45 FPS regardless of hardware power. This is often attributed to: The Ultimate Fix for Call of Duty: MW3

- Set Gameplay to Unlimited (or 300 if Unlocked isn't an option).
- Set Menu to 60 (this prevents GPU coil whine in menus, but doesn't affect gameplay).
