Rejected Lag/stutter on Higher Tower EU2-9

So, this has been a thing for a while, when there's over ~15 players on the server, there's randomly a quite amount of lag/stutter happening.

I first thought it's just my 1070 SLI, took it down to one GPU, nothing and other players started to tell same on chat too, so it's not on my end. Example i get normally quite high fps but it's randomly dropping to low 20 fps when there's that ~15 players or more. And this is happening daily. My ping has stayed same for most of the time(35-37), same with others.

If i try to describe that lag/stutter somehow, it would be like an HDD nor CPU is hitting it's limits.

 

Don't quite get what you mean by that "server-side lags".

Anyway, went and played another server running highertower that was full of players and didn't get that kind of lag.

 

Thus far that cl_disablehtmlmotd 1 seems to help, not as bad anymore, still some tho.

As you meantioned ads, i started to remember that this has been a thing as long those ads started to pop during waiting to spawn time after death.
Before ads were only at start when joined to server.

 

Dont wanna ruin the way of thinking here, but does it happen everytime you play on the server or was it a one time thing?
Because there is something called lagbots. Valve said they fixed it but from people i heared that they are still a thing.

Maybe n0 knows more of it or someone else who played on that time.

Just pointing it out. Feel free to delete if its not needed or unrelevant. Just trying to help to find a solution

 

Well it's mostly everyday and another have noticed it too..
Looked up those lagbots, looks similar lag, but there has not been any lagbot spam on chat tho.
And mostly server has known players playing.
