I can confirm . I have had with the launcher since day one. Every time I start the unreal launcher it brings my internet connection to it’s knees. Even browsing the internet while the unreal engine launcher is active is impossible for me. Seems to me there’s a major flaw in the launcher that takes all the bandwidth available. The even stranger part is that i’m on a 180Mbit connection allowing me to download with 22MB/s the launcher itself how ever doesn’t go faster than a few hundred KB’s if I’m lucky (100/300KB’s max)
