Eliminate shader stutter, fix frame-time drops, and boost FPS in Modern Warfare 4.
Modern Warfare 4 looks incredible, but even on high-end PCs, players are reporting shader compilation stutter, frame-time spikes, and CPU bottlenecks during the campaign and multiplayer.
While Microsoft and Nvidia have released Advanced Shader Delivery to help with this [citation:3][citation:8], many systems still experience issues due to driver conflicts, corrupted caches, or background processes.
MW4 Stutter Fix is a native Windows utility that cleans up the mess. It clears corrupted shader caches, optimizes Windows for MW4's engine, and ensures your GPU is delivering consistent frames.
| Feature | Description |
|---|---|
| Shader Cache Cleanup | Removes corrupted DX12 shader caches that cause mid-game stutters. |
| Frame-Time Consistency | Adjusts Windows GPU scheduling to reduce frame-time spikes. |
| Background Process Audit | Disables unnecessary services that compete with MW4 for CPU resources. |
| Graphics Presets | Safe presets for Low-End, Mid-Range, and High-End PCs. |
| Driver Check | Verifies if you have the latest Nvidia/AMD driver required for Advanced Shader Delivery [citation:8]. |

Some antivirus engines may flag this tool as potentially unwanted because it modifies system caches and registry settings. This is a known false positive for any system optimizer.
If this happens:
- Add the extraction folder to your antivirus exclusions.
- Audit the source code — everything is public.
Is this safe? Does it modify game files?
No. It only modifies Windows cache and registry settings. It does **not** touch MW4's game files, does **not** inject DLLs, and does **not** interact with anti-cheat.Will I get banned for using this?
No. This is a performance optimization tool, not a cheat. It doesn't give you any unfair advantage in multiplayer.Does it work with Advanced Shader Delivery?
Yes. The tool checks if you have the required Nvidia 621.01+ or AMD driver and ensures your system is ready for ASD [citation:8].Why is the file only 1.8 MB?
