Overwatch ping higher than shown

It reports as having 105ms to Amsterdam. I get 125ms ingame. Also the RTT calculator seems to be incorrect for advanced mode since it says the lowest I can get is 125 (145 ingame) when Auto Select → FR Marseille gives me 105 (125 ingame).

Could you please confirm that it’s also same with Full VPN mode enabled?

If it works fine with Full VPN mode enabled, it means there’s something a problem in the game item of Mudfish.

Full VPN mode doesn’t support the advanced mode does it?

No. It doesn’t support it in Full VPN mode.
