Actually, the server controls the game mode. The lag compensation mechanism rewinds time for players of all ping so that what they see on their screen is what they’re interacting with. When you shoot a player, even if you have 5ms lag time, the server goes and rewrites history so that what you shoot is what you were aiming at. When a player with 300ms lag does the same thing, the server rewrites history (just more history) too. There’s no advantage or disadvantage to be had depending on your ping - in fact without lag compensation, players with high ping would be severely disadvantaged. What’s happening with lag compensation is not that you were sentenced to death 100ms ago, but rather you were running for 100ms based on a prediction that turned out to be false - the prediction that nobody killed you in that time. Your death is retroactive. On 12 Mar 2014, at 8:54 am, Jermin Hu <[email protected]> wrote: > Of course low pingers have a disadvantage.
