Are all official servers 30 tickrate?
I mean all of them, not some country having it different?

I have been reading that conflicting topics about how to properly set your lerp settings.

This is recommended settings for vanilla servers, according to this guy

https://steamcommunity.com/sharedfiles/filedetails/?id=247881457

cl_cmdrate 30 // max command packets per second sent to the server DO NOT SET > FPS
cl_updaterate 30 // max update packets per second received.
cl_interp_ratio 1 // lerp time ratio.
rate 30000 // max download bandwitdth in bytes/s
cl_interp 0 //final interp if > cl_interp_ratio/cl_updaterate

IMPORTANT: Your cmdrate is limited by your fps. If fps<cmdrate then OUT/s=fps. This means your out/s will be inconsistent. This is VERY bad. Make sure your fps is never falling below your cmdrate - lower cl_cmdrate as needed.

Then, theres the other guide, which just says to put CL rates to 100, and the rate to 100000, which according to the link i put above is bad...

I read, that if you play on 30 tick server and put cl rates higher than 30, you get inflated ping, which happened to me, though it only went up by 10.

Im getting seriously confused here. Is it pointless to use 100 cl rates on official servers or not?

If i use the settings in the link, but change ratio to - 1 and cap cl rates to 30 and rate 30000, is it better for vanilla servers or not?

That still has conflicting information, im not intending to be a ♥♥♥♥, but

Some say to use rate to match 1000x the value of cl rates. On that guide they say to use rate of 30 000, and put cl rates to 100.

Also, in the link i gave he claims that cmdrate and updaterate are locked to 30, and in the guide you linked it says the updaterate is allowed up to 60.

As far as i know that is because official servers are locked to 30 tick, cl_updaterate rate are locked to max value of 60, cl_cmdrate are locked to max value of 100.
cl_interp_ratio are locked to 1
cl_interp are from 0 up to 0.5
and rate are locked up to 30000.000
You may put whatever you want as value in rate, update rate, cmdrate and interp_ratio. Them values are restricted by what server have set them to be

That is not true..
All rates are defined by the server you are joining on..
Does not matter if you use updaterate at 300, if the server maxupdaterate are set at 60, your updaterate will be at 60 too.

You guys are forgeting something, the max rate (default) for this game is 30000.
That is <30kb/s (29,29..) a value tunned from the 512kbps (0,5mbps) connection, with some tunning, a dial up connection (<6kb/s) can handle this game.
Theres no reason to "limit" the game, if it can do "better" and smoother.

Thats why some people "boost" their servers, with 66+ tickrate and 100+ updaterate, and unlimited rate value (0)..

Is it just a glitch then? I mean my ping? Also, if i set my cl rates to 30 and rate 30000, will they get changed by server as well or do those values have to be set higher to be capped to server settings?

It is changed by the server, but just as long as you are connected to it..
As you leave that server it gets back to its regular value.

ok, i just tested this out. I lowered cl rates to 30 and put rate to 30k, and my ping was 28.

I put the settings back this:

rate 100000
cl rates to 100
ratio to -1

and my ping was 40, so whats up with that? Is my connection speed of 50mb as bad as dial up ♥♥♥♥???

One thing dont have anything to do with another..
50mb does not mean better ping as 10mb..

It is just a coincidence, connection issues, or simple more data to transfer giving you a little more ping.

The game itself already works better with improved rates/tick, look at those pics:
https://steamcommunity.com/sharedfiles/filedetails/?id=1151720433
https://steamcommunity.com/sharedfiles/filedetails/?id=1151702724

Those pics are taken from a local host, same server and same client (me) on both pics, the connection here is 120mbps.
The only difference is the second one being tweaked tickrate/rates.

The game works better with improved rates and tick.

i wonder why this game is 30 tick instead of 66 like team fortress 2. Looking at those pics, 66 ticks would make wonders for the game.

Your lerp should be on the edge of white and yellow in the net graph, not orange.

Cl_interp 0.066 is what I use and works great for hit registration with everything else default.That and a high hz monitor like my Asus PG279Q, 165hz gsync, helps a lot.

If i leave everything else to a defaul, and only lower my lerp, my lerp value turns to yellow or orange. If i put rate to 100k and cl rates to 100, the lerp value stays white.

Im not sure if this is related to anything regarding connection settings, but i seem to get delayed firing with some guns. Like its definitely input lag, but the only thing thats affected by it is when i shoot. Its only happening with deagle, and somewhat on hunting rifle. If i keep shooting many times in row, the issue disappears. Only happens on online, but never when i play singleplayer mode.

And yes i use mods, but those same mods never caused issues before. Just dont understand how only few guns are affected...
