This sounds more like latency or what gamers call lag. Most games only use the 60 to 200 kbps for gaming. It's the latency or lag that gamers mostly gripe about.
Did you try it wired to see if it's your internet?
So when I'm playing a video game my task manager shows I'm getting as low 60kbps-200kbps out of the 3mbps so you can imagine I have intense latency issues. But even when the game is still running and I load a video to see if my internet is the problem, my task manager starts telling me its getting like 2.6 mbps bandwidth and then that stops as soon as I close the video. Is there some way to make my computer give more bandwidth to the game?
