Raise your hand if you actually know what lag compensation does. Oh nobody?
The lag compensation myth is up there with the "theater mode lag" in terms of ridiculous claims that really have no bearing in reality. https://developer.valvesoftware.com/wiki/Source_Multiplayer_Networking#Lag_compe nsation
What lag compensation does is to allow hit registration when a player lags. If a player has 200 ms of ping and shoots precisely at a moving target that has 50 ms of ping, then on the host's view, will be shooting behind the enemy player. On the shooter's screen, the hitmarkers will appear after the host receives the packets that say that the enemy was hit. A player with a better connection will still have an advantage, but a player with a bad connection will still have his shots register, albeit much later (because of lag)
I got my start in multiplayer video games with Mechwarrior 2 on a 56k connection. I remember the case insert had a message to "aim ahead of the enemy player to account for network latency". Without lag compensation, people would have to predict where the enemy players are on the host's view and aim in front of where it seems the enemy player is.
The reason why I think that the whole idea of "host lag" got started is from framerate drops in Black Ops and MW3. Framerate drops don't necessarily mean that a game is lagging, and just because a game runs smoothly doesn't mean it's not lagging.
I know it's a huge wall of text, but this idea that lag compensation is anything but good for the game is ludicrous.
