I'm noticing the same. No matter what SmartBOOST setting variation I use -- if someone is downloading a big file, like a steam download or console game update, etc -- my in-game ping (Rocket League via desktop/steam for example) will make the game unplayable. Even browsing/streaming can get really bad. How can I make it so large downloads/updates doesn't hog too much bandwidth? I have tried the Ping Optimizer, and while it says it's made big improvements -- in effect it doesn't seem to make any difference. Also I noticed when I'm playing in-game on Rocket League it doesn't show up on Network Activity under gaming.
