Here's what you will need to run Call of Duty: Modern Warfare 2's upcoming beta
For PC gamers, Call of Duty Modern Warfare 2's beta will start on September 23rd for those who have pre-ordered the game. To prepare for this date, Activision has released PC system requirements for the game's planned beta, letting PC gamers know if their systems are ready for the game ahead of time.
The good news here is that Modern Warfare 2's system requirements are on the low side, as should be expected from a cross-generation multiplayer shooter. These system requirements are expected to be similar to the final game's system requirements, though Activision is likely to recommend higher-end hardware configurations to play the game at higher resolutions, refresh rates, or visual quality settings.
 
Activision is expected to reveal more information about Call of Duty: Modern Warfare 2 on September 15th at their "Call of Duty Next" event. Here, we can expect to see some Modern Warfare 2 gameplay and get a look at Call of Duty: Warzone 2.
 
To play Modern Warfare 2 on PC, gamers can use graphics cards as old as Nvidia's Geforce GTX 670, which is a graphics card from 2012. That's right, PC gamers can play Modern Warfare 2's beta on a graphics card from ten years ago. Modern Warfare 2 should be a incredibly scalable game on PC.
