This is not about latency in 2023.
This is about server configuration, server & client performance.
For example, next set of software dramatically improve "so-called lag issues" in game.
accuracy_fix, reGameDLL 126.96.36.1996-dev, 1.9.0-dev+5210, and https://www.youtube.com/watch?v=gPCN_6aXl54
All of that crap - dramatically improve "so called" lag feeling in game.
In other words: shooting / action / motion in the game much smoother, predictable, and easier.
And in result people think that "server does not lag".
No, not really. This is pure path / algorithm side.
Try it, you will notice dramatic difference to default setups.
