[...] That's not strictly true, the server ticks at that rate, but there is no engine design guarantee that says the same about packets.
I didn't think I would get away with it but yea, server ticks is more accurate the packet rate does indeed vary.]]> generator=rsdiscuss&baseurl=https://staging.etf2l.org&feed=forum&forum=customise&topic=22896&post=410890 Fri, 28 Sep 2012 12:42:29 +0200 Reply by Dr. Chris https://staging.etf2l.org/forum/customise/topic-22896/page-2/?recent=410890#post=410888 Quoted from FireStorm
Oh and the reason for the recurring number is because the game sends a packets at a maximum rate of 1 packet every 15 ms which works out to the 66.666. Hz

[...] Because of lag compensation.
More the lack of it for projectiles, so when you increase your interp its like playing with a higher ping when you fire and see them since it means you are playing the game further in the past so to speak.

Why is it that if you set the maximum cl_interp possible (I believe it's 0.5), just for testing purposes obviously, projectiles have a significant delay between the moment you shoot, and the one it leaves your weapon (at least that's what you see client-side)? That's why I said you delay your client 'cl_interp' seconds.

You've got it the wrong way around. Interpolation happens to entity data being recieved, not entity data being sent.
Yeah, my bad, edited that last part in a rush because I had to go and wrote something that didn't make much sense. I know the data you receive is the one being interpolated but... damn I got it mixed up now lol.

Tickrate is (technically iirc) 66.666..., so what would that mean? that in optimal conditions the updates would vary between 66 and 67 per second? If that's correct, is 67 the maximum number of updates, or is it some other number (or maybe no limit?)?
The number of updates a second doesn't really mean anything, because it is possible that, for example, 132+ packets arrive in one second (hop delays, etc). Quoted from compleat
I understand the concept of interpolation, but the value one uses in cl_interp is used as the time the client has to interpolate, right? (That's why I said a "client side lag", you delay the sending of information to the server by 'cl_interp' seconds).

You can receive more updates than 66, it's just that that is the maximum tickrate.

It's not really a client side "lag", it's more of an "averaging" of the data (but yes, this does have a comparable effect).

What does the colours even mean in the lerp?
White = Normal Orange = Interpolation range < 2 / cl_updaterate Yellow = Server dropped frame Think of orange as being a notice that you are approaching the theoretical minimum lerp. It's not a warning or error.]]> generator=rsdiscuss&baseurl=https://staging.etf2l.org&feed=forum&forum=customise&topic=22896&post=410847 Thu, 27 Sep 2012 22:48:21 +0200 Reply by Compleat https://staging.etf2l.org/forum/customise/topic-22896/page-2/?recent=410890#post=410845 [talking about the interval shown by "lerp" in the net_graph] . This can be used to figure out why all of the objects in the world are no longer moving smoothly. In addition, the indicator will turn orange if the user or server has tuned the ConVars such that the interpolation amount is less than 2 / updaterate. This indicates that if there is any packet loss (or possibly choke if the choke is occurring for long periods of time due to large packets being sent over a low bandwidth rate setting) that the player will likely see sluggishness in the game.]]> generator=rsdiscuss&baseurl=https://staging.etf2l.org&feed=forum&forum=customise&topic=22896&post=410845 Thu, 27 Sep 2012 22:23:10 +0200 Reply by Luzik https://staging.etf2l.org/forum/customise/topic-22896/page-1/?recent=410890#post=410843 generator=rsdiscuss&baseurl=https://staging.etf2l.org&feed=forum&forum=customise&topic=22896&post=410843 Thu, 27 Sep 2012 21:45:50 +0200 Reply by Dr. Chris https://staging.etf2l.org/forum/customise/topic-22896/page-1/?recent=410890#post=410842 Quoted from Daerados

btw anyone know why with cl_interp 0 and cl_interp_ratio 1 my interp go 14.9ms some times? isnt 15.2 is a minimum?or its just a bug
This indicates a misconfiguration somewhere. Quoted from TviQ
[...] Im pretty sure 10.0 is minimun but i think ive heard its unstable or some shit like that but 10 is reachable
You're mistaken. 10 would only be reachable if you had 100 updates a second. This is possible in the old Source engine (as was used for a long time in CSS/etc), but is not possible in TF2.]]> generator=rsdiscuss&baseurl=https://staging.etf2l.org&feed=forum&forum=customise&topic=22896&post=410782 Thu, 27 Sep 2012 16:25:00 +0200
