Diablo 3 Lag Sucks!
Here are some samples to show how frustrating lag can be in the awesome game, Diablo 3. Most players use their in-game ping meter to help them figure out what their connection is like, but the challenge is that it is just a snapshot or average score, which doesn't really show you what your connection is like.
Having a smooth game connection is very important when you are in a twitch environment when every click matters. If you see a ping spike or packet loss, it can result in a lost move, and getting your butt kicked in-game. Often the further you are from the game, the chances something can go wrong will increase. But even if you are close to the game server, your connection may not be optimal.
In Diablo 3, some specific problems you will often see due to lag include delays getting your loot, health and spirit meter lag or super long teleport times.
WTFast helps to ensure that your game connection is as fast and as strong/responsive as possible. Instead of fighting with lag and your bad connection, you can actually fight your enemies and have a ton of fun playing the game as it was intended!
