Do you ever have anything nice or constructive to say in this Virgin Media forum? My ping has dropped from the mid 20s to the low 10s now! Hence I notice a difference.
I have things nice to say when circumstances merit it. I say plenty that's constructive.
Now onto the topic in hand: it's not a fix at all. It changes how the modem handles BQM traffic to make BQMs look nicer, it doesn't change how it handles the actual gaming traffic. The periodic jump about every 2 seconds in actual traffic persists.
Still if you think you can notice a difference in gaming because 'all BQM sites' you use look better and pings reported have dropped 1/100th of a second that's all good.
