Why You May Need a Call of Duty Booster for Better Game Performance
Before choosing the best Call of Duty booster, it’s crucial to understand why performance issues happen in the first place.
High CPU and RAM usage: The game consumes a significant amount of processing power and memory, particularly in large maps with tons of players. This might result in bottlenecks and FPS drops.
Background applications consuming resources: Browsers, antivirus programs, and streaming software run silently in the background, which can steal CPU, RAM, and network bandwidth from your game.
Overheating or hardware bottlenecks: Dust buildup, thermal throttling, or older GPUs/CPUs might cause the system to slow down to prevent damage during gameplay.
Poor system optimization: Junk files, outdated drivers, and poor Windows settings might also result in stuttering and inconsistent performance.
These are the core issues most players face, which is why many eagerly look for the best Call of Duty booster to achieve more responsive gameplay. Just read on to find the most effective fix out there!

How to Reduce Lag in Call of Duty Using Additional Optimization Methods
Now you know how to fix lag on Call of Duty with the best game booster. In addition, you can further enhance performance with a few manual optimization methods. These tweaks can also help you achieve smoother gameplay.
Step 1 – Adjust In-Game Graphics Settings to Reduce GPU Load
High graphics settings are one of the main causes of FPS drops and lag in Call of Duty, which places heavy demand on the GPU. You can try to lower the visual settings to balance performance and stability.
1. Launch Call of Duty, click the Settings (gear) icon in the top right corner, and navigate to the Graphics tab.
2. In the Display tab, choose Borderless Fullscreen for better performance. Match the aspect ratio to your PC display to ensure the best clarity.
3. Switch to the Quality section and adjust the settings, for instance, Texture Resolution, Depth of Field, Shader Quality, Particle Resolution, etc., based on your hardware condition.
4. You can also disable Ray Tracing for smoother performance or turn on NVIDIA DLSS/AMD FSR to boost the framerate.
Step 2 – Close Background Applications to Free System Resources
As introduced earlier, background applications consume RAM and CPU power, which can directly impact game performance and cause stuttering/delays during gameplay. But worry not. Here’s how to fix lag on Call of Duty by closing these programs.
1. On Windows, search for Task Manager and open it.
2. Identify unnecessary programs running in the background.
3. End non-important tasks to free up system resources before launching the Call of Duty.
Step 3 – Update Drivers and Windows System
Outdated graphics drivers are frequent culprits behind severe FPS drops, unexpected crashes, and hardware compatibility issues in Call of Duty. That’s why you need to keep your system updated to ensure the game can communicate optimally with your hardware. If you are looking for a hassle-free solution, Driver Booster is your best bet. The software can automatically detect outdated drivers, and you can update them in batches with one click! Here’s how.
1. Download, install, and launch Driver Booster on your Windows PC.
2. Click the large SCAN button in the center of the dashboard. The software will analyze your system to find outdated drivers.
3. After scanning, click the Update Now button to automatically download and install the latest versions of drivers.
Common Questions About Call of Duty Performance
1. Why is Call of Duty lagging even with good internet?
A stable internet connection only prevents network-related lag.
Performance issues can still occur due to hardware limitations. For instance, an overworked GPU, an overheating CPU, or insufficient RAM, etc. In addition, outdated drivers may lead to stuttering and delays, even when your bandwidth is high.
2. How to increase FPS in Call of Duty without upgrading the PC?
You can boost FPS via in-game graphics settings. For instance, lower hardware-intensive settings, disable demanding features like ray tracing, and enable DLSS or FSR. You can also turn on Windows Game Mode and close unnecessary background applications to free up system resources.
3. Why does Call of Duty keep stuttering during gameplay?
Stuttering usually occurs when your system can not maintain consistent frame delivery. This may be caused by background shader compilation, limited VRAM or RAM, CPU overload from other applications, or thermal throttling due to overheating hardware.
4. How to make Call of Duty run smoother on a low-end PC?
For a low-end PC, it’s best to set all graphics settings to low, reduce render resolution, and enable performance-focused upscaling(DLSS/FSR). You should also lock your FPS to match your monitor’s refresh rate and optimize Windows settings for gaming. Meanwhile, it’s crucial to keep your graphics drivers up to date for the best performance.
Final Words
Call of Duty lag and FPS drops are common issues for many players, but they can be effectively resolved with the right optimization methods. You can use a Call of Duty booster, adjust in-game graphics settings, close background applications, and update drivers to improve overall performance. However, if you want a more stable gaming experience with minimal effort, Smart Game Booster is the ideal solution.
