This sounds like a third party application is throttling your connection. Please make sure that any application you are not using is either closed or uninstalled.
Not sure how that could be when the only thing that is running while I play any game is Discord. I even tried closing everything before hand but it still happened. It only happens with Destiny as well. Incredibly frustrating.
If you go to Network and Sharing Center, click on Change Adapter Settings, right click on your Ethernet connection, and click Status.
In the speed section, what does it state?
I used speedtest.net as well as directly through my provider's website. Before I launch the game, the testers sit at 1Gbps. After I launch the game, it fluctuates between 10-25. I used Chrome, Firefox, and Microsoft Edge and I'm getting the same results.
It makes all webpages, programs and different games load much slower until I restart my PC.
Yes, and they weren't much help. That told me that it was a problem directly with the game I was trying to play. They haven't seen any changes to my speeds at all. We had a router update about a month ago, but the problem was happening before said update.
