On Windows, when using some Wifi adapters, in device properties > advanced tab, you'll see a setting called "Multimedia/Gaming Environment", it is disabled by default and you can enable it if you like.
I tested it myself and found enabling this will sometimes result in a slightly lower link-layer speed, but also slightly less packet loss.
Googling it will show up a lot of different explain for it, some says it's QOS, some says it lower the buffer, some says it's a frame burst technology, some says it allow more connections, some says it lower the ping, some says it trys to maintain a constant ping.....
So what does this setting actually do, officially?
