As of Lua mod 4.6.4, PPS has been removed.
In the server list, I see “PPS” next to servers. What is this? Is it ping?
PPS has no meaning anymore and is completely irrelevant. You should ignore it, it is not an indicator of ANYTHING.
If it’s high, that means NOTHING.
If it’s low, that means NOTHING.
-, that means NOTHING.
