What is QoS? QoS (Quality of Service), a security mechanism of the network, is a technique used to solve problems such as network latency and congestion. It is necessary for key applications and multimedia applications. When the network overload or congestion, QoS ensures that important traffic is not delayed or discarded, while ensuring the efficient operation of the network. In short, it is to improve the network priority of the game program to achieve the goal of reducing latency. The QoS policy is primarily for network applications.

As a result, the amount of CPU time allocated to the network will naturally be less, which will affect the speed ", so we can try to disable the service to achieve the goal of reducing game latency."
