Can flash games slow down your internet?

[Aj]

No its not a coincidence.

Because flash games stream data while they are in use, they take up more bandwidth, and so you get less bandwidth. Because of the way protocols work on the internet, you may experience degraded internet responsiveness, however the internet is not slowing down, it is just being used.

So for example if you have 50 mbps coming into your house and the flash game takes 25 mbps, then 25 mbs every second are not used and are left for other uses. So if you need to do something that takes 40 mbs every second, then the internet protocol will make choices to assign bandwidth and at some point trading of bandwidth occurs and the flash game will experience degraded responsiveness for a period of time.
