How to Fix Game Lag and Stuttering on PC

There are two kinds of “lag”: low FPS (the game runs slowly) and network lag (online delay). This guide tackles both.

First, identify the type

Symptom	Type	Section
Choppy, low frame rate	Performance	Below
High ping, rubber-banding online	Network	Below

Fixing performance lag

1. Update your GPU drivers — often an instant improvement.
2. Lower shadow and effects settings — the biggest FPS killers.
3. Close background apps — browsers and chat apps eat resources.
4. Set the game to High Performance in Windows graphics settings.
5. Check temperatures — overheating causes throttling and stutter.

Fixing network lag

1. Use a wired Ethernet connection instead of Wi-Fi.
2. Close downloads and streams using your bandwidth.
3. Choose a server close to you in the game’s settings.
4. Restart your router to clear congestion.

FAQ

Why do I stutter even with high FPS? Often background apps, a full hard drive, or thermal throttling. Check temps and free up storage.

Is Wi-Fi okay for online gaming? It works, but wired is far more stable and lower latency.

Conclusion

Figure out whether it’s FPS or network lag, then work the matching checklist. Driver updates, lower settings, wired internet, and cool temps fix the vast majority of cases.
