Change Lerp settings -> Cheat?

[mwob]

As you can see my question is about changing the lerp-settings. I sometimes noticed this in L4D2 Versus they kill some SI without really hitting them, they just shoot near them and they die. Also a tank in Versus hit me although i was ~3 metres away from him. In my opinion this is cheating but a guide for L4D2 says this is not really cheating. What´s true?

Servers always have to compensate for lag, the way L4D does it is if you hit that person on your screen they the damage is dealt to them

[bear]

Changine the lerp in general? Not cheating at all.

Toggling lerps for tank and other situations? Still not cheating just gay and pathetic.

Well Valve recently changed this in TF2 afaik and possibly CS:S or GO etc where a client cannot change these values unless in the main menu (not in a server) due to the fact it was being heavily abused.

Seen plenty of it (abuse of lerp values) in l4d2, would be nice if the devs done the same for this game and lock it so it can only be changed when not in a server.

Even though i know why ppl alter it, there are those who abuse it to no end.

Modified lerp in public games is obviously a cheat. Devs have ruined this game allowing access to this value to unfair players.

This is because spectators don't have interpolation, so they can't really see exactly where player aiming at this point.

You can read official documentation about interpolation and other technologies of Source Engine.
Basicaly, because only server decides if it was hit or miss, and interpolation is a client-side thing, it affects how fast you can see changes of the game on your screen. Keep in mind we talk about fractions of a second here(miliseconds).
Set interpolation too low and you will have "choppy" animations of common infected. Because game client can't interpolate CI with your lerp setting.

The bad thing is that server knows what interpolation settings players have and uses them in hit-miss-location calculations. If some cheating player plays a tank and sets his lerp to high value, higher than default 100ms, then server will use locations of players and objects "from the past" and from your perspective you can see how tank hits players from "long distances".

So to sum up. Interpolation(lerp) from 100ms to 0ms in theory will benefit players with fast reflexes and is not cheat because you still have to aim right and shoot with your hands to get kills. And players who sets interpolation to high values 200ms or more up to 500ms are cheaters.
Some servers use addons to track lerp values of players and will kick players with high values as soon as they detect them.

I hope this will clear things up and stop players from witch hunt.

clearly from ''FAIR-PLAY = EQUAL RULES 4 all paries'' standpoint it is wrong.once setting is not aviable trough GUI in game options = > creates question why it would be so.any deviance from characters /zombie+++/ known in game( e.g. tank will hit you only at certain distance) is wrong.perhaps cheat.Once tweaks /console/ do not serve purpose a) show fps/net/etc counter b) fix fps/net lag -in other words if they provide unfair advantage against others rather than fix issue.....it is not right..Mind you some game audiences do qualify lowering textures/effects off as same (cheating|) as grass/lack of light /looking into light were implemented into game for some reason-thus ballancing of strong and weak aspects were (at least) partialy dependant on factors mentioned above........and therefore boomer does not wear stroboscopic flashlight on his belly.
stay cool.peace and equality

so if it is only cheating a little bit its ok?

Clearly you haven't read official documentation and don't understand what interpolation is. You can try it yourself and I bet hardly see any difference in your gameplay.
Default settings were intended for PCs and Networks from 2009 year and since your modern PC and network connection allow you to opt-in and request information from server more often at computing power expense and set interpolation to low values to reduce latency for a few miliseconds. Valve even suggests it in official documentation.
Players who play competitive ( Confogl\ProMod ) all use different safe(<100ms) lerp values they like and no one argue and calling names.

but if you only cheat a little and still have to aim its ok?

Ofc it's not ok to cheat but changing lerps aint cheating.

As you and bulldogs say, it is highly abused so yeh it is a cheat anyone who says different has e peen issues

Most players look for excuses if they bad at games. Lerp has become one of that excuse.

If you care for lerp so much, then play Confogl\ProMod. Lerp changes are monitored and restricted there.

Why having to use special mode to have "normal" conditions ? You talk about technic while some people think about ethic ... so long

[jr.miqell]

like just had a go on scavenge for while..... joke. charger is hitting me from 5-7 metres (even if he at the end hits my teammate) I get ''3rd person '' time out...and quite contrary some are so ''mastered'' -they escape tank+charger+hunter while cornered....

I DID NOT SAID......not said it is because ''LERP''

or TWERP
or DERP
or YOURGRANNYSTEALSMONEY setting.....it might as well be something else

.What I said is-

IN THAT GAME/TYPE/ were some ODD RULES

.-NON CONSISTENT with USUAL RULES observed in COOPERATIVE

.Non consistencies observed on Special Infected abilities towards survivor-player (ME).
Those non consistencies did however NOT manifested themselves when I was ''Infected spec''

Put please Not blame on my hardware/sw/internet service provider as all of them well above recomended.not showing off right? but connection is best you can get as private entity,no other users of connection do exist.In sense PC is only thing connected to internet, no stupid phones,tablets,tamagochi or ip tv set.

apart from tank long arms the only form of cheating with lerp is when a player sets binds to toggle their lerp and rapidly toggles between very low lerp and very high lerp. this is effectively like using a lag switch, making jockeys and hunters near impossible to hit as they will appear to be stuttering and rubber banding around to other players. this is why 'competative' configs like promod and confogl strictly limit the amount of lerp changes a player can do per round and limit the maximum lerp to either 67ms or 100ms as far as i remember.

Valve could have limited the max lerp possible to the vanilla 100ms - as it is you can have up to up to 500ms lerp on valve servers! even 100ms is far too much - the standard lerp should be much lower, say 33.3ms/1 tick of interpolation, but valve designed this game to run on potato internet it seems...
