This issue comes up in waves each year. I’m not sure what the cause is, as I’ve never been able to replicate it. Due to the recent posts, I decided to test a few game downloads for titles I’m not currently playing.
Here’s my D4 install from last week. The connection never dipped below 100 MB/s.
Yes, it is possible other factors cause this, such as a slow/old drive, security software, or connection throttling. It’s tough to pin down the cause as it might be different across the group of people experiencing it. For instance, one report was maxing out the available download bandwidth without disconnecting the rest of their internet connection. Here’s that case.
