Is MW2 lagging on your PC? If you are facing this issue, you come to the right place. In this post, MiniTool Partition Wizard offers you 8 solutions. You can try them one by one.

Why Is MW2 So Laggy?

MW2, short for Call of Duty: Modern Warfare 2, is a 2009 first-person shooter game developed by Infinity Ward and published by Activision. It is available on Windows, PlayStation 3, and Xbox 360.

Many people report that they are struggling with frequent MW2 latency spikes. Why is MW2 so laggy? The possible reasons are as follows:

  • Insufficient Hardware Configuration: MW2 requires at least an i3-6100 / i5-2500K or AMD Ryzen 3 1200 processor, 8GB RAM, and a NVIDIA GeForce GTX 960 or AMD Radeon RX 470 graphics card with 2GB VRAM.
  • Game Server Status: Sometimes, the MW2 lagging issue is caused by Modern Warfare 2 game servers, like bugs, or under attacks.
  • Network Congestion: If there is some network congestion, bad routing, bandwidth congestion, or some network overloading problems, you will see high ping spikes over 100. Lag is usually associated with high ping in games.
  • Background Apps: Some apps may run in the background, which consumes the CPU and GPU resources.
