I'm playing this game for a long time but still I got lags every game. It's not HW lags because other games are going well.
I have it just every 5-10 minutes I got about 10 seconds LAG and I don't know why. My Internet connection is good and latency is always very good but this lags annoying me 
Do somebody have the same issue? Or do somebody know how to fix it?
I was already posted this on GG.net too in Forums: http://www.gosugamers.net/starcraft2/thread/497103-game-lags/
They said something about GFX Fan.
|
Can you post your computer specs? There's a bug in a recent Nvidia driver that causes graphics cards to overheat because it messes with the default fan profiles, so it would be nice to know if you were using an nvidia card.
|
Sure I'm using nVidia.
ASUS M2NPV-MX AMD Athlon 64 3500+ GeForce 8800 GTS 320 MB ZOTAC 3,5 GB RAM Windows XP Professional
I know they fixed something with ATi cards in patch 3.
|
I found the internet can get clogged with this game easily. I can do everything else on my school's wifi and I cannot tell the difference, but the moment I turn on starcraft 2, if I'm not on ethernet the game just doesn't work.
|
I don't mean to hijack the thread but I actually have a similar problem. I have very good internet connection and a computer that can run the game on best settings no problem.
I get little lags for ~1-1.5 seconds maybe where everything is completely stuck and then the game goes on and for ~0.5 seconds everything that happened in the meantime just flies by as it catches up. It's really weird and happens maybe once every two minutes in-game. Now, the weird thing: it doesn't happen when I watch replays. Never. But it does happen when I play against AI.
I have no idea what this is. I have graphics set to maximum but it also happens when I turn it down. My specs:
Vista 64-bit Home Premium Intel E8500 2x3.16Hz Core2 Duo CPU 4GB RAM NVidia GeForce GTX 260 More than enough HD space
I have the most current NVidia drivers that you can download, not the ones that melt your card but the ones Blizzard told people to use instead.
I guess it must be the internet connection but I have the fastest DSL speed you can get in Germany and everything else is super fast (including SC1, never had lags there).

Definitely sounds like a internet/connection issue with SC2 or BNET2.0
Not saying your internet is bad, but maybe you have something that is stopping packets from coming in or not sending some packets out. When your game just kinda lags for a second and comes back really quickly that's your game trying to catch up.
Maybe you have a firewall up or something? Maybe check your CPU usage when you play SC2, if it uses 100% your PC kind of freezes a bit (happens to me in L4D/L4D2, I fix it by setting the priority of the task to low in task manager).
Should post it up in blizzard support forums so the devs know about it and fix it if its something to do with the client. Good luck with it xP

Exactly the same problem here, I thought it was a HW issue since my specs do not meet minimum requirements. However, with all settings set on lowest, it will run semi-decent, but I get those 2~3 second pauses and then the 0.5 second when the game tries to catch up. I am on cmu school ethernet, and it is very fast (I've seen anywhere from 500k ~ >7mb/s download speeds!)
|
I have the exact same problem. Thought my router might suck, but maybe not if others are having the same problem.
|
Downloaded recommended nVidia drivers but it's still lagging.
|
I get this too.. Really weird.
I have almost identical computer as you TS.
I had to turn my computer off today, was feeling like the graphcard would burn down or sth.. really much noise + heat from the computer Looks like ill have to get new comp to play this game.
|
This sounds like what happens when I try to game on wireless.
|
Striker, my tips for u is to post on blizzard.com forums, they might help u a lot better than us, people here seems to have the same problem, so go to blizz forums and ask there, some people even work for blizz posting there. gl btw.

Ok,
My brother couldnt even get battle.net to work because of the lag in the graphics.
Heres the topic: http://forums.battle.net/thread.html?topicId=23425769546&sid=5000
The solution you are looking for could be there, so you might check it. What we did was this: 1.Run regedit 2.go into computer>HKEY_CURRENT_USER>Software>Blizzard Entertainment>Battle.net 3.Delete the dirtycacheindex registry Read the whole thread before you do it. Hope it helps!
|
And I thought I was the only one...
Same problem, computer of around minimum requirements, little above it. Got nVidia and proper drivers (not the latest until they fix that).
I doubt it's my internet since it's usually fast and steady. Also, they whole game freezes, lag doesnt make your sound screw up..
|
I installed that drivers they suggested and in the middle of the game I got Blue Screen of dead. So now I'm installing back the newest ones :D
Will post there since nobody knows nothing about it.

I know this sounds silly, but your video card could be overheating due to dust buildup. I've had games freeze/lag even though it doesn't seem like my system should be taxed. If you're computer isn't brand new there may be some significant dust build up. It's especially common in video cards with a fan like this:
Dust can build up inside the heat-sync and you won't be able to see it when just looking at your card. The best way to clean it is to take your video card out of your computer and use a vacuum with a soft brush end. You can also put it on reverse to try and blow some of the dust out, but go outside or open a window first. =p
Sometimes, if your card really hasn't been cleaned in a long time (over a year) you can even use a tweezers to pull the dust out. I've pulled a wooly-mammoth of out one of my old Radeons before. Something like that can really tank your card's capabilities as it keeps overheating and has to cut back.
Anyway, maybe that will help some of you guys out. Not necessarily the case for everyone, but something to check. xD

I have this one: + Show Spoiler +
So I will try to do as you said And if smth happen to it I will blame you to buy me new one
|
But there's a difference - my problem (and the one the people that posted below me) NEVER occurs when watching a replay (where the gpu surely works as hard as it does in-game). I think that rules any of the gpu- and fan-related sources for the problem out, no?
Striker and the others, do you guys have your lag problem in replays as well?

uhhhh you might wanna roll back your nvidia drivers. They announced on their website that their latest drivers are causing ALOT of geforce cards to overheat and melt. This is a huge problem, and has wrecked alot of video cards already.
Here is the link where Nvidia directly says DO NOT download their latest drivers (196.75) due to it causing fan problems.

Exactly. I've had about 5-6 different WLAN cards and they are all different in terms of lag. Some don't lag at all (very rare). Others do lag every ~20 sec for about 1 second only on B.net, another card lags every minute about 4 seconds while playing CS... WLAN just sucks. If any of you guys use WLAN, that's most likely the cause of your problems.

This, I had same problem and finally my fan just stopped (old ati radeon card)
I had freezing lags for few seconds after some time. Then when I used any 3d related games/programs my comp would crash.

there's one thing i can think of, and that is that the sc2 equivalent of "warden" runs in all those other cases, but probably not during a replay.
|
bnet 2 is sensitive to your latency. you can create a game with just yourself and no AI, and if your connection lags, you will notice the stuttering.
it might not necessarily be causing your problem but since you mention the lag never occurring while viewing replays, your connection or some program affecting your connection might be the culprit.
|
I've had this exact problem
It happens even when I have played the single player (not latency) (yes the real single player.. not through bnet (replays etc)
I switched video cards, same problem. It is NOT overheating (I have good drivers and know the nvidia issue)
It is not overheating or latency issues.
|
Same for me. My pc is hovering around minimum requirements, but generally I have about 40-50 FPS, and 20-30 during engagements.
It seems like those screen freezes happen most often when new unit is built or upgrade finishes.Screen just gets stuck with looping sound for like 5s, even though I can move the mouse just fine.

same exact thing
it seems to happen far more often on a fresh bootup of SC2, if ive been playing a while it stops happening
|
It happens to me too, but I always thought it's cause my comp is sucky and can barely run SC2 on lowest settings (so I figured some random moments I may lag up the game). Guess I'll clear the dust and see if that helps.
And just as dacthehork above me said - it's a lot more common in my first few (especially the first) game(s) after starting SC2 up, it almost vanishes after a while. Pretty weird.
|
Nope I'm not using WLAN.
I tried to clean Fan and GC and it didn't helped. Bad
|
Correct me if I'm mistaken, but I've stumbled a couple of weeks ago over a thread with a comparable issue in which somebody recommended to add
framecap=60
to the settings file in the Starcraft II Beta folder on MyDocuments.
For me that didnt work out, tough I had perfectly working hardware. I use Windows 7 so I finally decided to reinstall the whole client making sure I ran it "as Administrator". Worked out for me and since then it works flawless.
Hope it may helps

Its pretty funny to see that almost no one in this topic mentions lost packets. I guess there is no such thing in US/Western Europe countries  Usually such lags occur if you had a significant packet loss. It seems that Bnet 2.0 uses the same crappy netcode as SC1 and WC3, and this code cannot handle packet loss. To verify, press Win-R, type "ping eu.battle.net -t", wait for few minutes, then press Ctrl-Break. More than 5% packet loss means huge lags, 2-3% means some lag. You can't ping us.battle.net directly, so do the following: "tracert us.battle.net", find out the last IP address that allows ping (does not block ICMP traffic), and use that IP instead.

DId this just start happening to you?
I've played more than 300 games and this happened to me for the first time yesterday. In 2 of the games I played (2v2s) it would lag, then catch up. I'm wondering if it only recently started happening.

I definitely dont think its packet losses, it's something based on HW on client side cuz all the sounds keep looping too (like when you press ctrl+alt+del in windows 97). This usually happens when my first extractor pops and im watching it.
|
Are you playing on US server? I'm from Europe and I play on the US server, lag is almost unbearable at times. I can't micro worth a damn.

But it's sometimes lags only game not the sound. Sometime both but usually the first thing.

^ true.. I have noticed that this never happens without a disconnect window popping up on my friends computer, which is significantly better than mine (same network though, we both live on campus). Maybe it is a connection issue after all? Never had this problem with any other game though...
|
It sounds like a potential bug in the game to me. Internet lag will not cause your sound to skip. This means that it is something on your local computer that is causing the cpu to spike.
It could be a pathing issue where some units end up searching the entire map for a path to a location, or it could be some deep engine thing where it gets into a loop that takes awhile to exit. I recommend you report this issue to blizzard so that they prioritize it.
|
I'm already on it

I have the same problem here Untill today i made 500 games and i had not a single problem up to now But suddenly i get this 1-2 sec lags every 5 seconds and it makes the game unplayable for me
|
got this too, since this evening. played 200 games absolutely smooth and lagfree and now, the last ten games were hardly playable. so i guess I'm not the only one having trouble with this? hope blizzard will fix it soon. cannot ladder like that.

i have the same problem

It rather sounds like a router with bad quality of service. So when someone else is using your connection and surfing the internet or some program does a check in the background, the router prioritizes that instead of the sc2 traffic which is therefor delayed.
If you want to simulate with ping packets, do not forget that a default ping packet is pretty small. You should increase the size with the -b option (calculate it depending on your bandwidth) and increase the default wait time accordingly (else it will display loss which is no real loss, just takes too long to transmit).
On the other hand I have seen it a few times now that my opponent lags for 2-5 second when a new unit of me finishes production. Oo
|
Maybe it's a BNET2.0 problem... or what SilverSeraphim mentioned about dust buildup in graphics cards. I clean out my graphics card pretty often for the reasons he gave.
|
lag started today, not only for me but for many others in germany (or eu probably), so it has to do with blizz eu server.
just hope they can fix it quickly

Still have this problem
makes me lose games  I ran cpu fan to check temps and nothing spiked.

I'm having the exact same problem.
3.333 GHz 2.50 GB of RAM ATI Radeon HD 2400 Series Realtek HD Audio Output
Every 5 min or so skips for 2-8 seconds, loops sound. Happens even in replays. I tried the recommendation of going into the registry to find dirtycache file, but it wasn't there, am I doing something wrong?
For anyone wondering the minimum requirements are:
PC Minimum Requirements: • Windows XP SP3/Vista SP1/Windows 7 • 2.2 Ghz Pentium IV or equivalent AMD Athlon processor • 1 GB system RAM/1.5 GB for Vista and Windows 7 • 128 MB NVidia GeForce 6600 GT/ATI Radeon 9800 PRO video card • 1024x768 minimum display resolution • 4 GB free hard space (Beta) • Broadband connection
|
someone said before to run as administrator. That helped him, might help you
|
I have a quiet shitty internet connection, and for me it lags for 1 second every 10 seconds.
With other games I usually dont get this, just have a quite big delay.
|
same problem as the OP. I'm starting to think it's just a bug in the beta... Nobody have any solutions yet? The Battle.net thread didn't say much either.

Mediocre.wolf feel free to add me
|
i don't know if this will help you or not but my computer was stuttering all the time and i fixed it by blowing the dust off my heat sinks. stopped pausing every 10 seconds now.
|
Does the lag strike again? Since today i have this same spiky lag i had 4 weeks ago Is it just me or does it lag for anyone else too?
|
What type of lag?
Try pressing ctrl + alt + f to show your current FPS. If your FPS is dropping low then it is your CPU that is overheating and is probably down clocking itself, There are a couple free programs to see how hot your CPU is getting that may also be the cause. If it isn't your FPS then it may be the network that you are on and you are just having bad network traffic.
Hope this helps.
|
Ok, i just checked the FPS and it doesn't drop My CPU temperature and my network traffic are also fine Some of my mates experience the same lag now But somehow only my german mates are affected, maybe it's a regional problem regarding the server?
~edit~ The game freezes for 0.5-2 seconds and then runs with 6x speed untill it cought up That happens frequently all 5-10 seconds
|
I have the same problem. My housemate and I share an Internet connection, and he never gets the lag, so I don't think it's a problem with the Internet Service Provider. My theory was that it has something to do with loading a new graphic or sound. For example, when my second Overlord pops out, it could have a slightly different model during the 0.2 seconds it takes to "grow" to full size. Similarly, when you create a new unit for the first time, you may need to load a new sound--for example, "Thor is here."

Starcraft 2 definitely has an issue with card fans/over heating.
My GTX260 fan kept getting really loud after a while of starcraft sessions.. not long after the game would lag really bad. I'd go to restart but it would bluescreen+crash when starting back up..
took me a while to figure out it was a heating problem, but now im pretty sure it is because it would always come back after 15-20 of cooling off.
I'm not 100% sure if it was my cpu over heating, or my video card. I cleaned them both out and haven't had problems since... but I don't think i've been putting in as many starcraft hours.
|
Same problem. Fuck Blizzard.
|
|
I find that I get lag spikes every once in a while if I am NOT streaming the game xD
|
Same problem here, happened at least once in 3-4 games during weekend. I can normally move in game, select units and buildings, music keeps playing, similar to pause. Usually it just unfreezes, got also few "fast forwards" (quick catch up in time, looked like fastestx6 in rep) and two discs I think (both games were won ).
My connection is fine, so is my hw, I have new nvidia beta drivers etc. I hope it gets fixed soon.
|
I know it's an old topic, but here's a "fix" of some sorts in case anyone is still expierencing this weird stutter-thing
Petemctee.petemctee Here's a fix that I've found that works for me... (I don't understand why it works....)
Open up an internet browser and go to youtube then start the game.
I'm serious, it works for some reason....
http://forums.battle.net/thread.html?topicId=23425770071&sid=5000&pageNo=12
As funny as it is, it did work for me. It seems that now whenever I'm "supposed" to get this stutter, sound gets bugged, but screen only freezes for a split second instead for the full duration (3-5s). Weird
|
TCP packets over UDP packets, this is the reason for the lag that seems unexplainable. Blizzard decided to support only TCP packets not UDP. TCP is the standard packet type (in other words at any given time there is a metric tonne of them populating the internet and/or most networks). UDP is a less common packet type often used for video games to avoid clutter with TCP packets. Blizzard really seems to have dropped the ball on this one.
