If you read deep into the community and play something like modern warfare 2 2022 (mw2) you'll see quite often the game seems to purposely lag players and decide outcomes on a per engagement basis. kill cams show a totally different set of events than what you saw on say a decent PC such as running around a corner and you shot first but kill cam shows the opposite. they aren't just doing de lag or whatever they are balancing kill death ratios too.
