O COD4 é um jogo de velhas!

Well this is what wikipedia had to say about it.

In computing and especially computer networks, lag (slang) is a term
used where the computer freezes and than continues some time later when
an action is used, for example clicking. If there is different latency,
such as distance between computers connecting, the term used is delay
although many get it mixed up with lag.

Latency is the time taken for a packet of data to be sent from onetime
for encoding the packet for transmission and transmitting it, the time
for that serial data to traverse the network equipment between the
nodes, and the time to get the data off the circuit. This is also known
as "one-way latency". A minimum bound on latency is determined by the
distance between communicating devices and the speed at which the
signal propagates in the circuits (typically 70-95% of the speed of
light). Actual latency is much higher, due to packet processing in
networking equipment, and other traffic.

While strictly every packet experiences lag, the term lag is used to
refer to delays noticeable to the user. There is often a correlation
between latency and the physical distance that data must travel. Thus
the time taken for a packet to travel from a computer server in Europe
to a client in the same region is likely to be shorter than the time to
travel from Europe to the Americas or Asia. But protocols and well
written code that avoid unnecessary data transmissions are less
affected by the latency inherent in a network. Modern corporate
networks have devices to cache frequently requested data and accelerate
protocols, thus reducing application response time, the cumulative
effect of latency.

In many online video games, internet lag is undesirable because it
disrupts normal gameplay. Due to this, many players that have a lower
speed internet connection are often not permitted, or discouraged from
playing with other players or servers that have a distant server host
or have high latency to one another. Extreme cases of lag may result in
extensive desynchronization of the game state. The game may attempt to
correct this by pausing gameplay and attempting to fully resynchronize
all players. Games that do not or fail in the attempt may simply drop
the offending players.

Call of Duty 4: Fight the Lag

digg_skin="compact";




If, while playing Call of Duty 4 on Xbox Live, you see me join a game only to leave 5 seconds later,
please don't think I'm some kind of game-hopping n00b. I have a good
reason for visiting game after game like some kind of nomadic... er,
nomad. That reason is lag,
which all Aussie online-gamers will be intimately familiar with.
Unfortunately Call of Duty 4 is not immune from this problem. When I
get a good connection (as represented by green bars) the game is fantastic, with the best players inevitably placing well on the leaderboard. Once the connection drops to yellow- or even worse- red bars,
all bets are off. Skill has little to do with anything, and blind
firing with a submachine gun on full-auto is the order of the day.
It's really very disappointing when
you empty a full magazine into the enemy, only to see them stop, prop,
and drill you through the forehead with a carefully-aimed shot. All this could have been avoided if COD4 players were provided with some kind of connection filter,
allowing us to filter out all games below a certain connection level.
I believe that HALO has this option, as do 99% of online PC games. As
it stands, we Aussies have two options: 1. Hope that a friend is online and playing in an Aussie-dominated game (with a spare spot available to join), or 2.
Spend 30 or 40 frustrating minutes searching for games, connecting to
them, and then immediately leaving upon discovering that you have a
woeful connection. I'm sure that all it would take to end this misery
for Aussie gamers is for a small patch to be released providing the
connection filter option. In the meantime all we can do is hope and
wait...

Citação :

I know several Aussies having the same problem, all using different
ISPs. The problem is that you can't prevent the COD4 from connecting to
high-ping games... there are no filters etc. The first you know about
your game being high-ping (bad connection) is when you're thrown into
it! (and people start killing you

Citação :

I have stopped playing cod4 online because of the frustration i get
from lag. I can play games like FEAR Combat on the PC just fine because
i can choose a server i want to play in based on Ping. If i keep it
under 100, the connection is great. It would be really nice if
Microsoft would implement this function for Xbox Live, instead of the
slow, ugly, heavy behemoth that matchmaking is.

Citação :

Honestly lag is there even when you have green bars. Even so its by the
milisecond, that milisecond will kill you. How many time have you've
been aimed and ready to light up someone walking around the corner and
they kill you first? They actually walk around and see you before you
see them and start shooting. Or when you run into someone exchange fire
- COUNT YOUR SHOTS - DIE - and when you watch the kill cam it shows you
didnt even fire 1 bullet...?

Citação :

I am getting spanked around in CoD4 and don't know why. I land 3-5
shots to the chest, with the m4 carbine, and the guys don't die, but
when i see the kill cam after i die it only takes 1-2 shots to my legs
with any gun to kill me. I use stopping power and deep impact for my
perks and still don't rack up kills. I took the sniper riffle one round
and i hit this guy with 2 bullets square in the chest and he didn't die.

Citação :

Best thing I do is land shots to the head. Because the M4 has
considerable accuracy it should be easy. Here's another thing - never
stop moving. Even when shoot close range. I normally walk side to side
so that the enemy has a less chance of hitting me. Circling works too.
I use the M16 more because it has a more powerful show [you can easily
kill someone with one to two shots but be careful because there is no
automatic fire (only burst).

Now, like I was saying about
moving. Always keep pressing on that sprint button. Even if you can't
shoot your almost guaranteed to knife them. There has been so many
times when people are shooting bullets at me but since they are unable
to kill me, my knife as the reach to kill them.

Don't go
prone. The worst thing you can do is go prone. People can walk right on
top of you and knife you and you have no chance of getting out. It's
better to always keep your normal stance because you need to be
aggressive. Bullets don't wait for the player to move out of the way -
make yourself an attempt to get out of there yourself.

Don't
use silencers. They lower accuracy. ALWAYS USE RED DOT SIGHT. For the
best in accuracy use that one. ACOG SCOPE is useless in small
environments while the red dot site is good for all. If you haven't
unlocked it yet, use the normal one with the GRENADE LAUNCHER. You can
wrack up some kills using it so you can get the new site [its the next
unlock]. RPG's are almost useless and take up time. C4 or CLAYMORE are
a lot better but using something more like SPECIAL GREN. X3 is a lot
more useful for close encounters. I always use more than 1 grenade and
that perk helps me out every time.

If you plan on using a sniper
rifle, only use the original one [the first one] or the BARRETT .50
CAL. The rest suck and are wasting your time. The first one is either 1
shot kill or 2 shot kill with incredible low amount of recoil per shot.
The Barrett is almost a guaranteed one shot kill even in the back. If
your not up to the rank, use the first one.

those bars dont have to do with ping, that is the speed, like say for
some reason your internet is being limited to under 50kb/s download or
25kb/s upload you will be in the red, it could be a ping issue but that
is why it goes down, its not a direct relation to ping. As for the
shots. when I get killed, on the replay it shows me only shotting once
or twice when I practically unload my whole clip on a guy. Yesterday I
did pretty good though, I was having around +10 k/d spreads almost
every game except the levels I just haven't found a grove in yet.

Assim FAZ MAIS SENTIDO... se calhar as BARRAS não são o PING, mas a quantida de informação (UP e DOWN) que cada um consegue fazer, e é nesses dados que o algoritmo escolhe o HOST.

FAZ SENTIDO!

Mas afinal:

Citação :

No, I'm pretty sure the bars tell you your ping. Here's a quote I found from a user named tdoll22 from another forum:

Here's what guys on the Infinity Ward forum wrote me about the ping!

Ping
is time it takes to send a packet to the host. If the host is in Europe
or Asia and you are in the US there will be a longer travel time so
your ping will look bad. Also Ping or Latency DOES NOT correspond with
bandwidth. There are several factors that could affect your ping, hops
is the biggest. If the routing tables have you hit 3 or 4 different
switches just to get you out of your ISP's domain that will affect the
time it takes.

Just to give you an example while in college we
did a traceroute from my house to the school, 5 miles away. The route
went from my house, ISP office in our city, Chicago, Kansas City,
Chicago, to the school. Now I am in WI so it went around the country to
go 5 miles.

You got a bad host. If you enter a game with orange
ping, I suggest you just leave the game and search for another host if
you usually get games in the green.

It's not just the lag, i figured out how to get past the hit
detection., this is cheap and needs to be fixed, but, instead of aiming
for peoples chests i aim for their legs now and i clean house. for some
reason it picks up on all the leg shots but only picks up maybe 1 in 3
chest shots. Sometimes when it gets laggy i can tell too, like if i run
to knife a guy and on my screen it shows me knife him but on the kill
cam it doesn't show my guy get his knife out i know its lag.

With the COD4 feature patch having received good initial reception
from the community it's a bit surprising to discover that some players
are reporting problems. Specifically there are problems with the
host-migration feature that was supposed to help the
connection problems. It seems that gamers outside of the Americas are
having trouble getting a host who is local enough to them that they can
get a good connection. GeekPulp was able to get a response from the Infinity Ward Community Manager, Robert Bowling, who had this to say:

"That
doesn't mean it will always choose a US player, but I understand that
the odds are typically stacked against some of our more remote players
to be selected as host. We're currently looking at options available
that might help out with those odds and I'll keep you updated on it."

So hopefully we'll soon be seeing another
patch that'll fix the things that the first was supposed to take care
of. In meantime, to our readers overseas, have you all noticed any
effect on the game since the patch?

ping no COD4 em PC:



Na australia:

Citação :

yeah i was getting REAL REAL bad lag especially at night after 10pm when i was like looking for matches all i would get was european matches or US matches and i was always 1 bar connection. every single time.

it took me and a friend about 2 hours to find a decent match the other night so we ended up just playing cage much wich got old fast.

so yeah now im organising PSN get together every night at around 10:00pm AEST. for anyone interested in joining in we get around 15 players in our server all AUS people.

we have a hell of a lot of fun, there is a news article where you can sign up and post interest on this here

Latência sempre!

Citação :

COD only uses about 5-10kB/sec (that's kiloBytes)

it's the latency of your connection that matters (ping)

Já sabiamos que o WIRELESS por router é uma porcaria:

Citação :

Wireless connections are just plain horrible for gaming. Everything from cellphone towers to your neighbor's $29.95 dvd player can trip up your connections and cause lag spikes.

Try it with a wire and you'll drop at least 20ms off your ping, and probably kill most of the lag spikes.

Como em PORTUGAL:

Citação :

It is mainly due to the company we choose to provide our routes in Australia.
However, the main problem is how the Australian servers tell our connections to route.
As when our connections go from our provider to the actual server, they force our connections to take a specific route that doesn't cost them money as it goes via their peer's.
As we are not peered with the same people, our connections would ask for a different route, since none is specified, they find the next best thing etc.

Other providers probably don't experience this as they have different overseas route providers.

So the problem could technically be solved by TelstraClear changing route providers(highly unlikely as that would be a massive change over) or on the gaming server end, by allowing our connections to take correct routes(this has been explained to the people at Internode and various other gaming network providers, yet they refuse to try this, as they have nothing to gain).

At the end of the day, we are only one ISP, probably the only one experiencing this problem, so why would they want to help resolve this problem.

Citação :

I use TelstraClear cable because it provides the fastest, best ping connection for game playing, particularly when using trans-tasman links.

However, for at least the past few months I have noticed that connections to the Internode servers in Australia are unplayable (with latency increasing from 50ms to 200+ms).

Some quick googling of the terms "internode" and "TelstraClear" suggests that I am by no means alone, and that there is some kind of routing problem in Australia. Examples of other people complaining of the same problem include:

I fully agree, we need a numeric ping indicator. Or at the very least a 5 bar ping meter.

It's just stupid not knowing how you should adjust your play until you can shotgun the wall. Which you can't do at the start of any match, cause you need to rush weapons and get in your positions.

Hell, if you don't want others to know who host is, just tell us locally what our ping is.

Ping teste na XBOX:

Citação :

Ahhhh I thought you had found a way to check ping times whilst in the game, like you can often do on PC games. Pinging from the PC is not a reliable method with the 360 COD4 as I believe that it is a 'client hosted' game rather than 'server hosted'. In other words, one of the player's Xbox becomes the server rather than having a dedicated server hosted by say EA. If this is the case (and I'm sure someone will shout if not) you will get variable connections and variable pings through different games depending on who is hosting the game you are in.


Foxy... (I always said women had no sense of direction )

Lag is generally when the data is getting to the server, but slower than it should. So for example, when you press the fire button other players dont see you shooting until the server has received the information from your box. On a 'laggy' connection this becomes noticable, esp when you can see killcams. A player with a fast connection to the server will always have an advantage in this case. In comparison they are on red bull with lightening fast reactions, whereas you are erm.. 'out of it man'.


What you are describing is more like lost data packets, which is worse.
What happens is that you run around the map on your Xbox - your xbox tells the server where you are in the map and basically then the server chats back to your xbox and tells it where you should be according to it. What is happening is that some of the data which tells the server that you have run from A-B is never actually getting there, so when a bit of data does get there the servers says "Oh no you're not" and you get put back where it thinks you were. If this gets too bad you get the 'lost connection' icon and dumped back to the lobby. If this is happening a lot then I'd be suspecting your connection is a bit dodgy - first place to look is the wireless signal if you are using wireless.

Citação :

Killcam is a bit of a double edged sword. Nothing like saluting a fine piece of marksmanship but when you die and the shot looks like its in a different postcode it makes your teeth itch!

As for lag, I get it occasionally in a round, but then the next round is fine. You just have to suck it and see if you get a laggy host.

One day some boffin at MS will realise it would be a whole lot easier for them to set up a load of servers rather than getting us to host.

But that was the whole point of this thread...

Even if you didn't watch the kill cam, you know that you were aiming straight at the person you wanted to kill, and your shots should have hit him. Then, you feel just one bullet hit you from a normal assault gun (whereas it should usually take at least 2 or 3), and you're dead. You think "hmmm, something's wrong here". Then, you watch the kill cam, and see that you haven't even shot at the person, and they did shoot you 3 or 4 times... How can this be, when you didn't even see them shoot them? Hence, it's putting you at a big disadvantage...
