keyboard lag PC
basically as said in title. keyboard lags whenever I shoot, use ADS or do hold W and D together, it just doesn't recognize W in like 5 sec or so, feels like that button was turned off. it's not only...
It could be that the the input is sometimes interrupted by system or server LAG (test solo game / without internet). It could also occur that a button fails to respond if it isn't pressed down deep enough. I am not aware that BFV has a maximum button count per cycle but I am aware of this kind of game/engine limitation.
-remove unused USB devices / disconnect additional hardware
-try resetting the (custom) keyboard settings
-remove the BFV config > gamedrive:\username\documents\battlefield v\settings folder before starting the game
-try another USB poort
-update USB && Chipset software drivers
-update system BIOS
-check system temperatures
