Hi, this just happen today. When i launch any steam game, my internet become disconnected/very slow. Can't open store page, can't open google.
When I close my game, the connection is up again.

If i use other alternative internet like my mobile, it works fine.

Note: I just realize it doesn't happen to all game. If i open game like Resident Evil 4, or Persona 3 Reload, the issue happen.
Other games like metroidvania is working fine.

Anyone know what i should do?
