Do you mean the range-finder? Or how fast it is, if so later tanks have laser-rangefinders which are way faster then older vehicles and if not you can bind the range finder to whatever you want🙂
Là, c'est sûr,un bon pc c'est excellent, pour moi, j'ai un vieux pc et c'est compliqué, images saccadées,lags et j' en passe, très compliqué de jouer surtout contre les premuims.,.. trop de différences..,
