Last update was August 23. It's not Valve.

If its my side would an re install possibly fix it?

what makes you certain that the command isn't working?

most servers restrict cl_interp to be in the range of .0152 to .500

If you're unsure it's working, just put it to 0 and let the server take care of it.

I'm pretty sure 0 is messed up now.

OK, please excuse my lack of coherency. I start tf2, bottom right hand corner I have all the game performance indicators. fps, ping, in, out, lerp. (don't know what this is called sorry.) I open command console, I type in "cl_interp 0.01". When I did this before, my lerp number would change from "100.0ms" to "60.0ms". Know when I enter it, the number stays "100.0". I tried "cl_interp 0.05 also and nothing happened.

Edit: fyi: I'm doing this on the same servers as I did before when the command worked.

what's your "cl_interp_ratio" set to?

what does cl_interp do? I heard it helps with airblast?... not sure

Sorry, Ratio? Not quite following. Here's the numbers from my display in the exact same configuration as they were on my screen.

fps: 90 (<-jump map-usually 30) Ping:58
in: anywhere from 90 to 130 2.60k/s Lerp: 100.0ms
Out:60 to 80 3.9ks

20/s 21/s 21/s 21/s

type cl_interp_ratio into console and it should tell you what it's set to

I wish I could be more specific, but I'm not quite sure myself. I think it helps with hit scan weapons like the scatter gun. I think it reduces the time between shots fired and the scanning to see if a player was in the line of fire? I probably sound like a noob, but it's something like that.

Did what you said and this is the result I got.

"cl_interp_ratio" = "2" ( def. "2.0" )
client
- Sets the interpolation amount (final amount is cl_interp_ratio / cl_update

Mean anything to you?

That's interp_ratio.

try cl_interp_ratio 1
and you should really have cl_interp 0 or cl_interp 0.0152 in your auto exec so you don't have to type it in every time you launch tf2

That is called net_graph, you have it set to 1 (net_graph 1)

make sure that your other net settings are set to the "correct" values, you can find them in any of Chris' fps configs. Sometimes if you don't set your rates right the interp won't set right either.

here are the net settings that I use:

cl_cmdrate "66"
cl_interpolate "1"
cl_lagcomp_errorcheck "1"
cl_lagcompensation "1"
cl_interp_ratio "1"
cl_updaterate "66"
cl_smooth "1"
cl_smoothtime "0.1"
rate "25000"

and I use cl_interp 0.0152 for projectiles and cl_interp 0.033 for hitscan.

Let me know if this helps

I'm sure the article at the end will properly educate you on this but from what I've noticed visually and gameplay wise, when you use a high interp (the default is cl_interp .1 I beleive) it seems to increase the time between when your shot hits the player, and when the effects of the shot (not just damage) actually register on the player. If you use default interp and you shoot a wall with a rocket you will notice that the rocket seems to explode a tiny bit after the rocket actually hits the wall. with cl_interp 0.0152, the rocket seems to explode at the same time that it hits the wall. Also with a high interp if you shoot someone with a hitscan weapon you will notice that the knockback from your shot applies a little after the shot and damage applies, but with cl_interp 0.033 the damage and knockback are applied at the same time. There are technical reasons that we use values such as 0.0152 and 0.033 that have to do with tick rates and such of TF2 servers, and you can learn all of that stuff if you read this article: http://forums.steampowered.com/forums/showthread.php?t=1353969

Thanks for the reply. I noticed you mention something regarding Chris' fps configs. I do in fact use max frames. Are you saying I need to open the config file, find these settings and change them to what you stated in your post? I appreciate your detailed post, but I'm still a little unsure of where to enter these commands at. Thanks.

Thanks for the reply. I did in fact open the command console and entered the value "cl_interp_ratio 1, and nothing seemed to happen. Is it still working if I get no response from the console?

//cl_cmdrate 66
//cl_interp 0
//cl_interp_ratio 1
//cl_lagcompensation 1
//cl_pred_optimize 2
//cl_smooth 0
//cl_smoothtime 0.01
//cl_updaterate 66
//rate 60000

those are the "good connection" settings from chris' maxframes config. If you remove the // before each command, it will use them. He comments the commands out (thats what the // does) to disable them in case a player has their own net settings. So if you take it out they will apply. Try it and let me know if the problem persists.

Also there is no need to change to what my config uses, it was just an example that I had on hand.

Oh, and change that cl_interp 0 to cl_interp 0.0152 actually, with a recent update I think that cl_interp 0 messes something up

Ah the sweet sound of success. looks as if everything is know in order. Thanks for your help.

anytime my friend

good to hear
