Several factors can negatively affect your performance while playing games online. Often collectively described as lag, these factors can lead to a host of in-game performance issues, including:
Lag can also result in your getting booted from a match or from the multiplayer lobby while matchmaking.
What can contribute to lag?
Latency, also referred to simply as ping, is the amount of time it takes for data to travel between locations, measured in milliseconds. Your ping can be found on the Network Status screen within Call of Duty: Black Ops III.
Unfortunately, there aren’t many things you can do to improve your ping, as it is mainly dependent upon the quality and scope of your Internet Service Provider and your geographic location in relation to servers.
Call of Duty: Black Ops III’s matchmaking attempts to put you in matches with other nearby players in an effort to reduce the effects of ping. However, if there aren’t enough players close to you geographically, or if your ISP’s ping rate is high, you might experience some of the performance issues listed above.
You may, however, consider hardware improvements. Some routers specialize in reducing lag, while Linux-based models incorporate more up-to-date network drivers.

Network quality and connection
From time to time, even the best internet connections can suffer from data loss, also known as packet loss. While you can’t anticipate packet loss or prevent it from happening once data is sent from your network, you can tighten up your connection to help reduce the potential for loss of data.
Some of these tips will require you to log in to your router. If you're not sure how to do this, please consult your router's manual for instructions. If you do not have your router’s login credentials, you will need to contact your Internet Service Provider.
Bandwidth is commonly thought of as speed, but it is really the number of bytes that can be transferred between locations over a set time period, usually measured in megabits per second (Mbps). Most online games do not require a great amount of bandwidth, even when you are hosting a match. However, your available bandwidth can also be consumed by other sources, leaving you with less overall bandwidth for online gameplay and affecting in-game performance:

The latency experienced on an ISP is dependent upon the range and comprehensiveness of its overall network. When data packets travel between locations, the fewer points of exchange, the better. Direct routes will reduce latency and minimize potential instances of packet loss.
It is also worth noting that, depending on the scope of your ISP’s network, you may be more susceptible to packet loss when internet use is at its heaviest.
If you experience recurring latency issues while playing online, you may want to consider finding the ISP with the best connectivity options available in your area.
