So does the extra 480 horizontal pixels really make that anti tank weapon that much easier to use? If so, I think you have truly found the only possible reason to crop.
Playing the Demo:
About an hour ago, I picked a prone sniper off the roof of the hotel from the crane. (using the anti tank weapon. First Try. Just about 30 minutes before that I sat on the crane prone and let a guy by the hotel pool try to sniper me. He finally got me after about 9 richochettes or whizzing rounds. ( I was not even trying to hide, just prone looking at him)

I noticed when you use the site on the Anti Tank weapon, it acually zooms in about 30% or so. This means that the game engine does support some change of angular resolution............. I guess the sniper scope does too......even more.....if they can zoom positive can we zoom negative?
