Just taking advantage of the Steam summer sale and noticed that Steam downloads are classified as Gaming on the traffic monitor. Would it be possible to have Steam downloads classified as Downloading?
yes that's correct. We noticed this during testing. I'm not sure if it's possible to re-claissify steam downloads as 'downloading' due to the way the system works, but I will try and find out. It would make more sense to do it that way.
Note that Steam itself has an option for slowing/pausing downloads when you are playing online - so there is a workaround of sorts.
