Speeds of 10 Mbps and higher are good for gaming, but what you really want to consider when choosing an internet service for gaming is latency, or ping. Latency is the measure of how long it takes for your device to communicate with the server and is the main contributor to lag. The higher the ping, the more likely you are to experience lagging.
