Playing COD WWII i encountered a lot of "wow i should have beat that person to the shot there" . although i firmly believe you can sometimes fix lag, R1 will assist in that.. although it can only do so much when the video game developers introduce tools that involve lag compensation which ultimately determine your experience in game. even so for fps games. the developers design a system that tries to lower the skill gap between players that way the less experienced players can have a good game which in theory would keep them playing and buying dlc. this video will go into detail about some of the topics we discuss here frequently.
watch the video when you have some free time. it basically reiterated what i have an idea of regarding shooters & lag. and will most likely enlighten those of you who are interested in understanding why a player "sees" you first before you see them.
