Latency steady at 100 milliseconds is something a system can plan around; latency swinging between 40 and 200 makes it hard for the system to know how long to wait before playing the next chunk.

None of these have room to buffer — a late packet shows up as a stutter right then. This is exactly why "game accelerator" exists as a category: it is built for situations that are extremely sensitive to timing, not for "a webpage opened slowly."",{"type":7,"html":186},"Different genres of games are sensitive to these three in different amounts. A slower-paced or turn-based game can tolerate a bit of extra latency; a competitive game that depends on precise aim and split-second calls will show the effect of an extra few dozen milliseconds of latency or jitter immediately, in missed hits and mistimed movement. That is also why the same route feels completely fine to one person and unusable to another — they are playing different kinds of games, with very different tolerance for these three numbers.",{"type":14,"id":77,"html":188},"What a game accelerator and a VPN actually do here",{"type":7,"html":190},"A game accelerator and a VPN work in a similar way underneath: both pick a route between you and the target server rather than making data travel faster than it physically can.
