Intermittent lag issue in all games?

Archived from groups: comp.sys.ibm.pc.games.action (More info?)

Hi,

I suspect that some sort of network or XP related forum might be the ideal
place for this post, but I will also bet that there are peeps in here that
know more than most network experts when it comes to lag etc...

Anyway, I am experiencing intermittent lag/network freezes in the games I
play online - BF2, HL2, BF and mods.

At first I thought it was just BF2 as I used to get silky smooth play before
installing this, but I also reinstalled WinXP Pro before installing BF2 to
make sure it went as smoothly as possible (!)

My setup is: WinXP Pro (SP2 and patched up), Athlon 2.2, 1GB ram, GeForce
FX5900xt 128MB, SB Audigy, Maxtor 7200rpm 200GB drive, Hitachi 120GB drive.
Ralink 804.11g wireless network card, Belkin 804.11g wireless network
adapter/adsl modem. Internet is 1MB ADSL.

I have tried optimising the MTU, which is about the limit of my networking
knowledge. The figures I came up with suggested that 1500 would be ok, so I
changed both PC and router to reflect this. This seemed to make things
worse - certainly no better - so I took it back to 1400. Also tried
disabling ZoneAlarm Pro.

There seems no pattern to the lag/freezes except that they will happen at
some point - more often than not around the time I am killed (probably
occurs as a kill results from my lag, not the other way around?).

Any suggestions as to what else I might look at?

    See that it's not your internet connection first -
    Go to www.broadbandreports.com and do a line packet loss test against
    your public IP address (you'll have to register for free for this). I
    think the site will show this, or you can go to www.showmyip.com to see
    that as well.
    This will reall just go as far as your router's public IP address.
    Have you tried a continuous (ping -t) ping to an external host? Do you
    get intermittent timeouts or spikes in ping time?

    > Hi,

    I doubt this is the problem but on MTU some info for you I found some time
    ago on the netgear site

    Setting MTU size is a process of trial-and-error: start with the maximum
    value of 1500, then reduce the size until the problem goes away. Using one
    of these values is likely to solve problems caused by MTU size:

    a.. 1500. The largest Ethernet packet size; it is also the default value.
    This is the typical setting for non-PPPoE, non-VPN connections. The default
    value for NETGEAR routers, adapters and switches.
    b.. 1492. The size PPPoE prefers.
    c.. 1472. Maximum size to use for pinging. (Bigger packets are
    fragmented.)
    d.. 1468. The size DHCP prefers.
    e.. 1460. Usable by AOL if you don't have large email attachments, etc.
    f.. 1430. The size VPN and PPTP prefer.
    g.. 1400. Maximum size for AOL DSL.
    h.. 576. Typical value to connect to dial-up ISPs.
    I'm guessing your problem is more likely to be your new XP settings for your
    network. Others will have to tell you how to optimise that - sorry.

    Thanks - I'll try this and let you know...

    Erk.. Thanks for this - only problem is, I have my router set up not to
    respond to pings (I think) as the test was cancelled.

    I would guess that this is something to do with ICMP pings? I thought I had
    these enabled, but looks like I have more to learn before I can begin to get
    to the bottom of this!

    Regards

    Hi Schrodinger,

    Here's some things to try:

    1. I understand that BF2 comes with its own Beta nVidia driver. If you
    installed this, it would be my #1 suspect. (Even though it seems to
    be a network problem).

    2. If you've installed Ethernet drivers off of Microsoft Update,
    uninstall them and get the latest from the manufacturer's site.

    3. I usually find MTU causes problems when it is too big, so try making
    it smaller.

    4. I had a 3-way conflict between an Audigy 2, Punk Buster and
    audio/video that had to be seen to be believed. Basically I got an sound
    and video update twice per second and the rest of the time it was
    frozen. (Stuttering). Simultaneously I got LOTS of "Network Interrupted"
    messages from the game. Try yanking the Audigy and just running in
    stereo mode.

    5. If you have an Audigy as opposed to an Audigy 2, be aware it takes up
    more CPU cycles.

    6. I'm not familiar with your adsl modem, and you didn't list your
    motherboard, but whatever it is, it probably has an on-board Fast
    Ethernet port. Can you try swtiching to cabled Fast Ethernet? It might
    give you some hint as to what driver or component has gone wrong.

    7. 2.2GHz is an awfully high overclock for an old, non-XP Athlon. Do you
    have watercooling? Maybe you should crank it down a bit. Which model is
    it, anyway? You should consider upgrading to an Athlon XP.

    8. It could be your ISP. Try to find some kind of throughput or
    download tester that identifies pauses.

    9. Your ADSL modem might have a web interface with statistics. Check
    it out.

    Hope that helps. If you come have more questions, please tell us what
    Motherboard you have.

    ken.

    Unfortunately, the problems you describe may, or may not, be lag. When
    people say lag, they usually mean latency and/or packetloss. Out of
    the box, most home and SOHO equipment comes with networking
    preconfigured to meet the demands of most people. Sure, you can tweak
    things, but depending on your software, hardware, router, ISP, it may,
    or may not, make a difference. This is vastly different from the old
    days of dialup modems, where tweaking made a BIG difference.

    I state all this because your problem is most likely NOT on your end.
    XP Pro networking is pretty solid, and the stock configuration is fine
    for broadband. Again, you can munge MTU and stuff, but for 99% of the
    people this will make little or no difference.

    With your router, changing the MTU may make a difference, but then
    again, it may not. I have found that most networking issues are not
    user issues; they are ISP issues.

    So, go ahead and mess with MTU just to make sure, but if that does not
    work, realize that one of two things is probably the real cause:

    1. It is not lag, per se. You have some other bottleneck that is
    causing slowdowns, and results in laglike symptoms. Flakey or old
    drivers, a slow system, too much sound detail that chokes the CPU, too
    much video detail that chokes the CPU, etc.

    2. It is lag, and the problem is your ISP or an upstream provider. You
    will need to use tracert and ping to help determine if this is the
    case. If you run a tracert to your target game server and see 3
    initial hops with low pings and 0% loss, then one server with high
    ping and 5% loss, the problem is an upstream provider. If you see high
    pings and packetloss to your first hop (your gateway) it is your ISP
    or local cabling.

    #2 is hard to get any action on because most ISPs assume the problem
    is user related to begin with, and because most ISPs do not escalate
    issues with upstream providers very well.

    Good luck.
