FAQ Lag!

What causes lag?

  1. Game server is overloaded or badly reachable
  2. Your internet connection is bad
  3. Your computer and software can't smoothly display the game

What to do against lag?

  1. Game server is overloaded or badly reachable: This is something we work on by placing enough servers on the right places in the world. Actually, right now this problem is non existent. We are monitoring constantly to see if the servers are OK. Only thing you should look for, is if you are on the right cluster. If you are from Europe, play on the European servers, If you are from America, play on the American servers, etc.
  2. Your internet connection is bad:
    1. Don't use wireless, but a wired connection.
    2. Make sure wireless is turned off
    3. Make sure no software is running that uses the internet (also on an occasional basis). Consider shutting down Skype, Outlook, Torrents, Dropbox, and other software.
    4. Make sure other people on your network are not destroying your network (like streaming audio/video, downloading torrents, etc.) This is a common cause for lag in student houses
    5. Make sure your connection from your house is good (sometimes network providers, like cable companies or telephone companies, actually overload their network)
  3. Your computer and software can't smoothly display the game:
    1. ​Make sure you actually shut down and restart your pc, make sure no other programs are running (none!)
    2. Make sure you actually shut down and restart your browser, so you have an empty browser without any other tabs
    3. Now go to http://curvefever.com/play2.php directly
    4. Right click on the gamefield, select Low Quality
    5. Keep a look on your memory consumption in the task manager, it should not get higher than 64MB for Curve Fever
    6. Consider switching from one browser to another. The browser plugins for flash are in general very bad. In the past we have seen best results on Opera. However, if you are on an old Windows machine, (like Vista or older) we recommend Internet Explorer.
    7. Consider to restart the game after 1 or 2 games played.

To see if it is our fault or your fault, use this webpage to check your ping and jitter: http://www.pingtest.net/

Toggle Stats

Ingame you can also see if it is you, or our servers. If you press right mouse button and toggle stats, it will show you a graph of your performance. What it shows:

  • in yellow: your FPS (higher is better)
  • in green: ping with your actual room
  • in red: ping with a reference server in another data center in another country
  • grey lines show 50ms difference

All that matters in this graph is how high is the green line? And is the green line stable, or does it fluctuate a lot? If it fluctuates, does the red line also fluctuate? This results in the following 4 scenarios:

So 4 scenarios:

  • Your internet is bad: Both green and red follow each other in a high spike!
  • Your PC is bad: There is a drop from the yellow points to almost the bottom.
  • Our game server is bad: Only the green points go up significantly, the red points stay on the same level.
  • Our reference server is bad: Only the red points go up significantly, the green points stay on the same level. But this is not a problem, as you don't play on the (red) reference server. Only on the (green) game server.

 

And on a final note: http://rescomp.stanford.edu/~cheshire/rants/Latency.html

If you have further question about lag, or tips on how to prevent them, please leave it behind in the comments.

Best regards,

Geert

Hola, ultimamente he tenido problemas cuando juego, hace tres días no tenía lag, y últimamente cada vez que quiero jugar, no me aparece que tenga concexión baja hasta que ya estoy jugando, por lo cual he perdido muchos puntos en mi rank de ffa, en cuestión de segundos me dan las dos advertencias de lag, y me empiezan a dar pantallazos de "slow conecction". Me podrían decir, ¿por qué me está sucediendo esto? y ¿qué puedo hacer para que no me vuelva a pasar?.

With linux it may be hard because of different distributions of it - but maybe exporting on most popular ones (I guess ubuntu, suse and maybe mint), so most of the linux users could use it without making 100h of extra work. And if somebody is using... lets say debian on regular basis, im pretty sure he can make app/convertion of the game on his own Biggrin

OK, this has to stop already. Last two weeks, it was ok to play. Sometimes little laggy, but mostly ok. Not superb but just ok. Last two days, its horible. Horible... Whichever browser i use its horible. Just horible.  I dont have lags like there is showing frame "username lags", instead, my snake is constantly delaying. When u look at it, it looks like the tip of snake is on fire. Its not moving on a straight line when u let it run, instead it looks like sinusioid wave, with really small amplitude. Climax was yesterday night while playing game i could not turn for small angles, I mean, i can make turn only while i press nonstop my key, if i want to make more precise turn its not responsing. Causing me loose more then 100 points on rank.

When i look at toogle stats, ping varies constantly with minimum of 70 ms, while 124 is mostly regular. Sometimes it reaches 500, 600 and more.

Now i tested on my laptop using wifi server in frankfurt, while I live 831 km away, and that is the result.

And mostly ironic of all, i usually have less lags on laptop and wifi than on pc wired connection, while pc has by far superior hardware btw.

But average result is same, pc and laptop lags equally. My connection is ok. OK enough to handle flash game. Better then ok enough to handle more demanding games, then what the fuck is going on?  excuse my french.

It is interesnting also. before instaling new server, it was by far more pleasurable playing. Now its just FRUSTRATING. 
There are few hours in the day when i can play normaly and that is fucking 4 in the morning. Who plays at  4 a.m??

Also, before that new server my ping was max 35-40, in relation to now, that was not improvement, its a regress..

What a disgrace.

 

 

Now ignore this post like every other post , and tell me that "You will work on it." or "Maybe its my connection."

Thank you for reading if you did.

Hello Geert and everyone else! 

I'm writing here to get my curvefever ping back to normal again. I have played for like 2 years now and I've never had a problem with my ping and gameplay until 3-4months ago - and I cant figure out what the problem is, so I hope you can help me. And before I could play this game with a ping like 49ms ALL the time with uTorrent running, another games like GTA and dayZ in the background, 5-10 different windows in google chrome, spotify and still have 49ms and no lags. Now i need to close every single program that use my internet connection to not get lag warnings and input. And I'm the only computer who is using the internet in my apartment. 

 

In this thread you are saying that the lag are coming from this topics:

Game server is overloaded or badly reachable
Your internet connection is bad
Your computer and software can't smoothly display the game

So I have printed some things here I want you to look at.

 

First of all, here is a traceroute to your site in the program pingplotter:

Seems good, right?:)

Here I pinged curvefever.com with 20 packets:

 

Ping - 35ms.

And here is a TPtest so you can see the internet connection:

96down/85up in speed. 

My computer setup (with a graphic card AMD Radeon HD 8600 Series and a SSD hard drive):

 

I have done a traceroute with cmd to:

 

 

And finally, here is my ping in curvefever. This screenshot is with Adobe Flash Player, and I have exactly the same ping in Opera, chrome, firefox and internet explorer 11.

 

And here is some things I have done to get my ping back to normal:

Have tested 60/75/100/120 Hz on different resolution

Have tested 2 ethernetcables from the router to my computer

Have tested my computer directly to the fiber converter with 2 cables

Have tested to take out 4GB memory to only run on 4

Have tested to format my computer

and some small things like taking of antivirus, windows firewall and disable some other things but the ping dont want to go back to normal.

 

When I play other games outside sweden I don't have this problem. When I play games and the servers are here in sweden I have like 5-15ms all the time, and when the servers are outside sweden it's pretty much 15-35 and nothing over that. Only on curvefever I got this huge lags.

 

Can you please look into this?

 

And for the record: I have tested one another computer here at my homenetwork and that computer also have 143ms exactly. If I take my computer to a friends house (the friend does not have the sam internet provider that i have) and there it works perfect. So I asked another friend who have the same internet provider as me, and he also got exactly 143ms. So I have figure out that it is only my internet provider here in sweden who have this problem.

So the big question is if the problem is on your side, or our provider. 

 

Thanks!

like i said, at other topic. when i started plaing, no lags and normal ping like 10-20 but since some months, there are hard lags and this happen only at curve fever. and i dont chaged something at my connection, computer etc. so its clear that the problems are at the servers of curve fever, and not the players have them.

or geert, why you think are here sooo much lag-posts at forum, but before maybe 1 post per 3 months or less

if the whole thing goes red, it means the connection to the reference servers is bad (it overwrites the green dot). So probably your internet is bad. You might also benefit form disabling Nagle's algorithm:
 

Disable Nagle's Algorithm
​Nagle's algorithm squizes packages together to safe bandwidth. But this is unbenificial for your ping. So disabling it is a good thing. Go to google.com and type: Disable Nagle's Algorithm [Your OS] . For example, for windows 7: http://www.optimizemswindows.com/disable-nagle-algorithm-to-increase-you...

And without screenshots we can't do anything for you, unfortunately. Next time do deliver the screenshot.

It's not funny... I have too problems with key lags.
1 week ago I played without lags, so my question is: What happened?
I play on http://curvefever.com/CF_Preloader.swf ( browser: Flash Speak Slimjet ).

I tried all methods in this topic...

Speed Test: 12 mbps and 35 - 42 ping.

Ive tried to toggle the stats, and there I saw the red dots are up. This means my internet works just fine, since the ping with the actual room is perfectly normal. Therefore, the problem was at the reference servers' side. I do not know what this means for the lag in-game. I'll post a screenshot of it if necessary.

Key lag is solved, but not in the way it should be. The difference is that I now use another internet provider :/

Hmm that is wierd GameRich, since key input is handled DIRECTLY on the client, and does not wait for server confirmation.

T1 Predat0r,

Please read the first post in this thread, or I suggest you go here: http://curvefever.com/content/laggy-try-potential-solution-graphicsfps-lags. This highlights a problem with the latest Flash player and how you may be able to resolve it through installation of an older flash player. This is a common problem in recent weeks.

 

Good luck,

Hi, I experience the following problem since yesterday's update:

After a few minutes played, everyone complains I would lag heavily, teleport, etc. In contrast, I can play without any problems and nobody lags for me. All this happens in both the CF standalone browser and in Chrome. In Chrome, I disabled PNAPI 16.

My frame rate seems to be fine (about 60 fps), the ping too (30-35 ms), my PC is more or less idle and my upstream quite ok (0.8 mbit/s) according to several speed tests. To fix the problem, I uninstalled Flash Player 16 and installed Flash Player 15 as recommended in posting #1, and I even disabled Nagle's algorithm. But nothing seems to work.

What else can I do?

I don't want to annoy the other players, but of course I want to play too.

EDIT: The same in Firefox. And the same no matter whether i'm host or not. And the same even if I restart the browser before starting a game. Very frustrating. Please help me!

EDIT2: After realizing that there was an update yesterday, I think this is a bug introduced with this update and hope it will be fixed soon. Thanks for the quick reply.

Unfortunately, I figured out today that the bug has not been fixed until now. I played a speed game - the first one after 3 days of break - and received a ******** again. I fully understand the other players, but I lose understanding why this bug is still in the game. If you are unable to fix it quickly, why don't you rollback to the version prior to this fatal update that introduced the bug? I mean I pay for this game and want to play it, but in the current state it is impossible.

Psyphy,

The developers are working on the lag issues this week. Some major bugs were resolved in the previous update! However, you probably are aware that in solving some bugs you always appear to get new ones. We ask you for your patience as the developers get to work on solving these bugs. After all there are only limited resources available.

Hi everyone, 

i'm really asking for help now, cause i'm slowly loosing my mind with this lag. I have come to this point that i can't bear it anymore. When i joined the game i was immediately hooked, i was fascinated by how a simple online game like that can be so exciting. I was playing it everyday and i was never bored. But lattely (to be more exact after the latest upgrade) i started to have problems with huge keylag, that i never had before. To be honest i never had any problems with the game, when i was using a proper connection. But now its just a nightmare. For a really short period i stoped playing it, which resulted in loss of rank points. Because i played hard to get those points i forced myself to play it at least once a week or so, that i didn't lose more. 

Cause the lag got me just more upset, i looked on the forum, found this topic and decided to give the advices above a try. So what i did is following:  

- I disabled Nagle's Algorithm

- uninstalled the latest version of Adobe Flash player and installed the 15.0.0.239 version (and disabled auto updates)

- disabled the PPAPI 16 plugin

- restarted my browser

When i logged in the game after this, it was like a miracle, almost to cry for. I had no more lag, I didnt even knew anymore how does that feel. I had to get used to play again without lag. But then a few plays after that i was still fine, when suddenly everybody else around me started lagging (-.-). It isnt happening all the time, but when it is, it is worse then before..i couldnt even tell where the people were going, the lines were jumping like crazy.

So I'm kindly asking for help, because i play the game to relax myself and enjoy it, not to lose my last nerve.  

 

P.S. sorry if there are any mistakes in the comment, english is my second language.  

I also made a ping check on http://www.pingtest.net/ and in the game itself (Toogle stats).This is what it showed:

Todays update:

Hello there, reporting a new great thing. Today when i played the game the lag from others remains the same, but there is something new, something even better. Two times happened to me, that it was so laggy that i was going straight out of the playfield an others were drawing circles. So i went out, logged in the game again and wanted to join back, but guess what? There was no join back button anymore! So as a result i lost 20 points of rank today in one hour. Great succes, keep it up. 

And to be honest i'm not the only one complaining about the lag. In every second game that i play, there are complainings and i dont think they are all lying.

My opinion is that you should make it unranked (dont delete the ranks, just hide it) till you fix the problems for the majority. Otherwise i think its better to just delete the game, so the people will be calm and in the meantime you should fix it. When it would be working properly, then you should put it back on the internet again, open for the people. This just cant go on, people were patient for a long time, but enough is enough.

skategrizzly,

I must stress that putting the game offline won't be an option. That is not fair on the players who are not lagging - and there are a lot of players like this, including myself (on all 4 of my computers might I add). I can say from your toggle stats, your green and red lines look fine and only your ping is massively fluctuating. This implies to me that you have an unstable internet connection (or it could be your direct connection to the CF server).
The team are looking towards lag reduction lately. However, you are clearly showing connection lag. Most people are experiencing what we call "FPS lag" or "graphics lag" which is where the snake doesn't seem very smooth - and this is what the team are addressing. It is not common that people have such problems as yours - the more common thing is another type of lag which is separate from yours.

NOTE: there has been a potential bug identified which could cause users to lag in some games. This is another type of lag again - it's like your time reference is 0.2 seconds ahead of everyone else's. This is being looked into as well.

We kindly ask for your patience to see if any of these problems solve your issue,
Tranquility.

Hello everybody,

I've got the exact same story as skategrizzly does. I hope the devolper of curve will fix this problem fast because this is already taking to long. If this problem is for a day or two it's exapteble, but people, including me, are paying for this game for having fun, and it's not fun waiting for a fix for so long.

After 3 years membership of curve i am a bit dissapointed in the devolpers.

Trying the beta version didn't help.

The bug I described in post #28, which appears since the update on Feb 7, has not been fixed for more than 2 1/2 weeks now!

You asked for my patience two weeks ago but I'm really running out of it. If solving 'some major bugs' introduced such a giant bug (i.e., making the game completely unplayable!), the developers should better consider rolling back the fatal update.

By the way: It's no fun to be denounced as a cheater when the lags suddenly appear in the middle of a game (though I can't even notice them). I use to leave the game in these cases, but it costs me lots of rank points.

PsyPhy,

Please bear in mind there are only a couple of people capable of dealing with your issue, and they have to deal with the issues of many other users too. We understand your frustration, and believe us, we are frustrated too.

Furthermore, please note your laggy problem, although you are not alone, is not a common thing. So labelling it as a "giant bug" is possibly a bit of overkill. For you individually, then maybe! The bug is logged, and will be looked into. I can assure you.

Tranquility.

C'mon guys. It's one month over now and I still can't play. Sad What is different with me (and the few others) that I have this problem with any browser (even CF standalone) despite acceptable CPU speed and a good internet connection? Is it my Windows 7? Is it my account? I could create a new one if you transfer my premium status (+1 month please) to the new account. What is so special with my configuration?
