Of course low pingers have a disadvantage. In the lag compensation mechanism,
the high-ping players dictates the game world, not the low-ping players. That’s
why my opponent only need to focus on what’s happening the screen. If he hits
me on his screen, the server would think he hit me.
My game world doesn’t have the final say, because if it is, I shouldn’t die
after I run behind the crate.
Let’s say the server time now is 100 (unit: ms). Let’s assume itt takes no time
for server to process the received packets. That means when the server receives
a packet, it can immediately send out the packet containing the processed game
world to both players. And both players’ game client can render the received
packet right away.
My ping is 5 and my opponent’s is 45. At 100 the server sends out a processed
packet, where I have been running from south to north for 10 ms and my opponent
is aiming at me. At 145, my opponent receives the package, his game client uses
the packet containing data of what I was doing at 95 to interpolate (predict)
where I should be rendered on his screen at 145.
If I suddenly stopped and started running reversely at 96, his client is unable
to correctly predict it, because the packet he received only contains what I
was doing at 95 (100-5). His client still thinks that I am running to north.
After he hit me on his screen, his client sends the packet containing this
information to the server. It arrives at 190, and the server processes and
conforms the kill. Then it takes another 5 for the processed packet to reach my
computer. At this time (195), I actually have been running south for 99 ms. But
in the packet the server sent to me, I am already dead. That is I have been
sentenced to death 100 ms ago. The running I have been doing for 100 ms is in
vain.
What a big error! Keep in mind this doesn’t include server processing time and
client rendering time yet. And 45 is really not a high ping in my server.
This is what really happened when I get killed after I run behind the crate.
If low pingers have the final say, it would be the high pingers who suffer this
frustration.
P.S. I have tried turning off sv_unlag. It turned out to be a bigger mess.
Players can hardly hit each other when moving.
P.P.S. About the calculation of the theoretical max ping. We all know light can
travels around the earth 7.5 times in one second. That means every round takes
about 1/7.5 = 0.1333 seconds = 133.3 ms. The ping shown in net_graph too is
round trip delay. That’s the time taken by a packet to travels to the target
computer and back.

Subject: Re: [Csgo_servers] Lag compensation is punishing low-pingers?
Hey,
you're always stating that you have a disadvantage. It is not a disadvantage
since your enemy has (like you) no control how you are seen on his the screen,
and no control how he is seen on your screen.
Also, saying you have a disadvantage implies that he has an advantage, witch is
false. He has the same window of time than you when anyone peeks, which is what
I would consider fair.
"I think that as a person who provides (high-quality) servers for the community
for free, I shouldn’t receive an disadvantage when playing in my own server."
Let's exaggerate that: "On my own server I should be allowed to cheat, since
there could be chaters that could have an advantage".
I'm wondering why should you (or anyone) should have any advantage on your
server? In a fair game, no one has an advantage.
Now, I can just repeat what I just said: Since nobody has an advantage (It
isn't easier for the high-ping-player to hit you!) you don't have any
disadvantage.
If you really want to fix this, use sv_unlag, but please notify players about
this behavior, because it directly affects gameplay.
If you think: "People that are closer to the Datacenter should be harder to
hit" then you can enable this.
I still advice against it.
Best regards,
