> what are the system requirements for this game?

Depends on what map you play, how high the resolution you set the textures.

If it is a regular map, a gig or 2 ram.

If it is a city, with texture resolution set to as high as possible: 4gb or more gb of ram.

It just depends on what you are loading. How many weapons, how many models, how many buildings, which maps, etc.
