So since June i have been experiencing random ping spikes when playing Overwatch. It will happily stay around 30 - 40ms but during games it will spike to upwards of 240Ms resulting in heavy rubber banding and general lag issues.
I am using a Superhub 1 with all required Ports open as per Blizzards Tech site and Admins Instructions. I suffer lag on various other games also such as rocket league on PS4. Overwatch is connected via Ethernet to a PC and the PS4 is also connected via ethernet, their is no wireless connection used.
