I downloaded bf5 yesterday and have been having input lag issues in full screen so i was messing about with the settings and tried windowed mode and i found out that i get 45+ fps increase while in windowed mode which i thought was strange, as usually it doesn't make a difference in other games, i also found that my Cpu is being used a lot more in windowed so i am a bit confused to what is happening as i get a lot more fps in windowed but i have huge amount of input delay, and in full screen i have input delay but 40-50 fps less which i think is whats causing my game to have input lag in full screen. Is this some kind of bottleneck? i was going to buy a new Gpu eventually when i get the money.
