I am kinda lost to what I can do. I have a pretty new system (i5 8600k RX580 and 16GB ram) and I can't play any game that requires a wifi connection (like Rainbow six Siege and Apex Legends) and my GPU and CPU usage shoot up to 100% when I am playing, and my game lags so badly it becomes unplayable. This is not a thermal issue since they stay around 60 degrees. The weird thing is that this doesn't happen when I play an offline game (ex. Cities Skylines) and when I play the online games the network usage is like 2%. Can you guys help me?
