Explanation of Sponge(-ing)
Some people also refer to it as the loss of packets or the *hit* not registering.
I myself study IT networking so im very much capable of explaning what sponging is.
It depends on:
1. The location of the dedicated server/player host.
2. Your location.
3. Location of the client players.
Basically if the host is originated in the UK (which can be both the server or player host) and everyone in the game is in the UK or somewhere near that the sponging will be minimal or zero at best.
See it like this: everytime you interact with an in-game object (your weapon for example), fire bullets and move(rotate your camera, walk) a package gets sent to the host. This package then gets send to the target player or back to you. Depending on the distance between the target player or host the package sometimes returns damaged.
What happens is that the package gets *dropped/deleted* it won't register thus your shot will sponge or you will experience movement lag of some sort.
The success rate for the package to be damaged increases with greater distance.
It does not matter if you have a 120Mbit connection hell even with a 5Mbit connection you can enjoy gears, its all about the distance.
Dedicated servers are dedicated to hosting servers (just what the name says actually) they can handle hundreds of connections, it is like a place where everyone meets and shares information remotely.
If you get in a game and you live in the US and the game is player hosted in the US it will be a great connection for you (only exception is if the host is doing naug..downloading movies). Another player in the same team is living in Africa, he will get sponge after sponge, the packets that his game sends keep getting damaged so they get dropped everytime by the host but if you just send enough of them (repeatedly shooting) eventually 1 will get through thus register as weapons fire or anything.
"OMG! HE SPONGED I HAD TO SHOOT HIM LIKE 6 TIMES WITH ACTIVE!!!!" <- explained.
"Nothing wrong here, nobody is sponging for me" <- explained.
"They shoot me full red all the time but seem to sponge the last shot" <- explained.
Are there any more questions?
