According to the built in speed estimator, my speed is running at a solid 127 Mbps. This is hooked up to 5ghz band wifi. Why am i getting so much input lag? Fps games are UNPLAYABLE. Framerate as smooth is butter. I’m actually paying for 200mbps but yeah its wifi so its going to be cut down a little but there should be no excuse as to why games are literally unplayable. Why is this?

Check your ping. You can have all the speed you want and still have it lag because of a bad ping (0-20 is good -50 is ok and anything above that is bad)
