For one it can adequately show if your WiFi is performing well...

In a home network setting I've got a UDP display sink (64x64px, RGB) with a custom protocol. It works fine-- no hard number as the performance varies based on other factors, including congestion. I've been able to push it to >90fps, but around 42fps there is virtually no flicker.

For context in my protocol I use all 512bytes, with 3 first being the "line number and such" data and the rest containing ~128 pixels.
