: The most played map online, probably Factory or Docks, along with Office and Hi-Tech.
: Virtually any computer can run F.E.A.R. You won't have the awesome uber insane graphics like most other people, but, F.E.A.R was designed to be able to play on virtually any PC. You can have the graphics cranked WAY up and look awesome, or dropped real low and look ugly. Plus, if you want to further increase your FPS, you can use the DX8 shaders instead of DX9, giving you further frames and possibly a higher level of detail. The thing with F.E.A.R is that you can run it on nearly any PC.
