Since the SC2 beta (I formatted my computer just before installing) started I've experienced a peculiar problem, when using full screen mode my game will slow down from the standard 60-70 fps to 1-3 for 5-10 seconds time. It seems to happen at completely random times, I've reviewed the same parts of the game where it slowed down through replays and the fps doesn't necessarily drop at the same exact spot or close to it. I've tried multiple video card drivers and am now using the ones suggested by Blizzard (197.13). None of them have helped with this other than some of the newest drivers causing my game to crash completely resulting in artifacts appearing on the screen. I run the game on the lowest possible graphics.

Things relating to this I've noticed:
In campaign mode the fps drop often happens even in windowed mode.
In campaign pressing F10 to pause the game will result in the fps going back to normal. Unpause and the fps drops again no matter how long you wait for.

Hardware:
Windows XP SP3
Nvidia 9800GT
AMD Athlon 64 x2 Dual Core 5200+
4gb RAM
Plenty of free space on HDD
Please tell me if you need more information/more specific.

Overheating? I've monitored the temperatures while playing and no significant rise can be noticed. It stays at around 60-70 celsius. Doesn't seem to be related to the fps drops.
SC2 related? Not necessarily, I've noticed this happening in Quake Live and Urban Terror as well but very rarely compared to SC2. BW/WC3 doesn't happen.

Any ideas would be greatly appreciated. Google nor the Battle.net forums have been of great help so far but knowing TL I am not hopeless yet.

edit: Problem seemingly gone after fucking around with a ton of settings, switching drivers like a mad man and opening my PC case.

I have an identical problem. I was hoping that someone would post a thread like this.

Athlon 64 3500+
1.93GB of RAM
NVIDIA 8800 GS
XP SP3


EDIT: I've noticed that the FPS drops often happen when something new appears on screen, like an enemy unit or an alert on the minimap. This makes the problem especially frustrating since the game seems to freeze whenever I engage in battle!

Yeah I had exactly the same problems as you two. I noticed that there are some parts of the maps like the 1st hatch in the whispers of doom Zeratul mission that ALWAYS lag, no matter what.
I noticed too that the big talking avatars like Swann when he introduces new units tend to lag like hell.
I'd appreciate any help with this aside from lowering my settings :|

When I turned off 3D portraits, it seemed to help, but it didn't solve the problem completely. Judging by how noisy the hard drive is during the freezes, I would imagine that the problem lies with switching textures or models or something from the hard drive to the RAM. Just a hunch.

This happened to me in beta after patch 16 on my old computer. Never found a fix for it. All settings Low and whatever possible off...still happened.

My new computer is significantly better, and I've not had this problem. The main differences are:
CPU Intel P4 -> AMD
GPU nVidia -> ATi
RAM crap -> craptons

I doubt the problem is RAM, as I played patches 6 through 15 with no problems at all. I'm almost certain it's the CPU since changing video drivers did nothing.

[edit]
So the problem is on older Intel and AMD CPUs?

No, Puosu has a dual core AMD CPU. It's equivalent to an Intel Core Duo, which falls under the "recommended" category for SC2. So that can't be the issue.

Core Duo is old as hell, and if he had an equivalent AMD dual core, that means it's also old. Core 2 is even old. I wouldn't recommend anything less than AM2+ sockets or Core i3s. I'm trying to collect more info from people for a LP2 page about hardware configs with FPS on whatever settings and any issues that might occur, but nobody has given me anything yet

I believe I have the same problem. SC2 recommends Ultra/maxed out settings but then whenever something new appears on screen it lags for a second then everything fast forwards as it catches up. Repeat 100x every game .

It's especially intensive at the start of each mission/game.

I imagine it's a combination of low IPC, low RAM (< 4GB), low VRAM, and well, slow scratch disks. Who knows, if you have all of these, your experience will suffer haha.

However the OP has a relatively modern GPU and 4GB RAM so hmmm. CPU is definitely way old, but doesn't explain the drop to 1fps. Could be an HD on its way out, but I doubt it.

HDD shouldn't cause this, especially since models are loaded into memory for use, and just displaying one wouldn't access the HDD.

Yeah, so I guess something with the NB/RAM? I mean RAM would BSOD if it was bad (and it isn't). Doesn't mention anything on OCing either, but maybe check NB temps? Really only a problem on the early NF4 boards, I dunno.

In my case I'm 99% certain it's all because of my single core cpu.

also have the same problem, but thought it was because of my single core like above poster. It IS in fact a bug however, it's been posted on blizzard tech forums in beta so many times but they didn't seem to be able to solve it. I've tried downclocking, lots of settings and driver tweakings but to no effect.

Also I think it only happens on (older) AMD CPU's. Someone confirm or deny please?

*edit* and to me it is unique to SC2, I've never had it happen in any other game.

Always turn VSYNC off. In BNet, and in the ATI catalyst center.
(especially applicable if your FPS seems to drop in halves...i.e. 60->30->15 or similar.)

No, vsync or any graphic options does nothing, as most of us suspected it's CPU related. I don't know whether to buy a new motherboard or to wait for a patch (but I doubt they'll fix it anytime soon), it's pretty frustrating playing online with all these fps freezes. You micro some reapers and FREEZE... SPEED UP BAM ALL DEAD.

Here's how you will fix it (ATI Users)

Right Click -> Catalyst Control Center -> Your Card Name -> 3D Settings -> Standard Setting -> Optimal Performance.

I've had this problem in StarCraft 2 and WarCraft 3, and it's all fixed, no more FPS drops etc.
Have fun gaming !

I also have had this problem since day one of the beta, and for some reason blizzard wont even respond to our posts anymore. Its insanely annoying, it makes micro impossible. I play alot of toss and i notice that every time i build my first sentry it freezes and then fast forwards. It seems like everytime a certain sound is played for the first time this happens. At first I thought it was for sure because of my single core because alot of the new games have been having problems with single cores, but after reading alot of posts it looks like its not just limited to single core.

AMD 3500
8800gt
2 gigs of ram

Ive tried every possible solution to no avail. It really pisses me off that I paid 60 bux for this game and blizzard just seems to be ignoring it. I really hope they fix this soon.

I have also been getting random drops in fps ingame, and it was after turning down my shaders and shadow ? I have no idea but I didn't experience this during beta.

6000+
GTX 280 SC
4gb Corsair XMS2

It's gotta be my CPU for me, but for others not so sure. my VGA used to be able to carry the load on all games, SC2 is the first to show how big my bottleneck really is.

I have the exact same specs as the OP and I noticed that disabling Cool'nquiet in the bios seems to help a little bit. But what I find curious is that no matter what graphics settings I have on starcraft 2 (low-ultra) the framerate never deviates from 30-40 fps which is very... odd....

I bought a completely new PC to play SC2, and I have the same issue (even on lower graphics settings - medium and low), so it's definitely not related to slow computer components. So please, I would appreciate if anyone would stop saying "upgrade your CPU or something". My setup is:

Intel i5 750 quadcore
nVidia 9800 GX2
4GB RAM
Windows 7

To be honest I don't see any trend in the rigs people are posting for this issue. Some have ATI cards, others nVidia, some are Intel and others are AMD. It's really annoying though, as I lose a lot of ladder games due to this sudden drop in FPS.

This should be optimized by Blizzard! I gave 1500 euros for a new Laptop (G51J) and still cant play at all High. To be honest the game is not that demanding but I guess they are waiting for us to buy new PCs and then optimize it which obv sucks

Eh you would be the first with a modern CPU in this thread. Everyone else has had a Northwood (2002-2004) or A64 (2003-2005 era). All of my friends are on Conroes or better (Lynnfields) - none of them have reported this issue.

You do have a dual-GPU system, which makes it vulnerable to bad SLI profiles. That is a reason I stick to monolithic GPUs. I saw my friend deal with that too many times when he has his 9800GX2 2 years ago (and 295 more recently). He's on a 480 to avoid that nonsense now.

I disabled SLI, but it doesn't make a difference. Even the FPS stays more or less the same, and the same issue still occurs.

Oh and to be complete: this happens anywhere in the game, no matter what is going on. I've had sudden FPS drops while I was chatting on the bnet interface screen. Or in the Hyperion cantina while I was checking out mercenaries. It seems totally random, and unrelated to what is going on. Clearly a bug or incompatibility issue, and not a performance issue.

Just my 2 cents. I play on a laptop, Core2Duo T5550 (1,83GHz), 2GB Ram and Nvidia 8400M GS. Its not the best setup, but sc2 recognized it to play on medium. Which i CAN'T do because of these fps drops. I put everything on LOW, and the game is now playable. On medium i could play the game NORMALLY, i only had the sudden drops when I selected a new unit (disabling 3D portraits make this better), and when something new occured on the map. Every time a warning poped up on the game or on the map BAM fps drops. It normalized but when i had to move the camera it droped again... If my camara were stationary everything was fine the moment i tried to move it, i got the fps drops, even when nothing was happening.

Only solution for me: Play the game with everything on LOW.

And even with stuff on LOW i tried to enable 3d portraits again and i got small but some fps drops, specially when something poped up on the screen during the mission.

Do any of the people with this problem have a good sound card? If not, the game is probably using default drivers with a small ram cache. When the game tries to play the sound and it's not in the cache, it loads it from the hard drive and stalls the game.

Just a theory, of course.

I can play on medium, i only can't play when i have to move the camera, even if there is NOTHING happening across the map. Sudden fps drop, if my camera remains stationary the game runs without any kind of problem. Not a processor problem here IMO.

Did you run http://www.guru3d.com/category/driversweeper/ or something similar before changing drivers? Leftover drivers can lead to instability and crashing.

I have the same problem as the OP.

The only thing we have similar is XP SP3.

I noticed a lot of XP in this thread. Anyone think there's some causation? Or is it just people running XP tend to have older computers?

You should try running driver sweeper which I have posted in the thread before your post to remove any old drivers before installing new ones. XP is actually quite decent and rectifies driver issues people are having with other OS.

The only thing we have similar is XP SP3.

I noticed a lot of XP in this thread. Anyone think there's some causation? Or is it just people running XP tend to have older computers?


It's the latter. The OS is not the problem here.

I got a problem with sudden fps drops, sometimes my sc2 drops to 1-2 fps for some reason, it happens randomly, sometimes as soon as the game starts and sometimes later in, and sometimes even when i watch replays....

Never happened in the beta and i think it started with the latest patch, not sure.

specs:

INTEL CORE 2 DUO E8400 3.0GHZ 6MB 1333MHZ S-775
ASUS RADEON HD4870 512MB DDR5 PCI-E DVI
CORSAIR 4GB DDR2 XMS2 PC6400 (2X2GB)

win xp

I run the game in medium and 1440x900 Fullscreen.


Thx

Ok... I give up!!! I've waited.. read, looked for help, uninstalled and installed new drivers(gpu, chipset, sound), formatted drives and when I drew the line - there was NO IMPROVEMENT at all!

I'm currently using this machine:

ASUS G51J:

Windows 7 Home Premium (64-bit)
Intel Core i7-720QM (1.6GHz, 1333MHz FSB, 6MB Cache) up to 2.93Hz
NVIDIA GeForce GTX 260M 1GB GDDR3 memory
4GB PC3-8500 DDR3 SDRAM (2GB x 2)
Two 320GB Seagate 7200RPM Hard Drives

Additional info:

Nvidia 258.96 drivers
GPU Temp: around 85 (normal for Asus)
Core Temps: Low 61 High 80


I bought it 3 months ago for 1500 Euro, so I can play sc2 on high AND guess what.. I can't play it even on medium.

Ever since the BETA patch 7 my sc2 performance is getting worse.. unplayable for competitive games I would say (FPS around 70 on high and medium but every minute or so it drops down to 15-25 FPS AND this is VERY annoying). Even after I capped the FPS in variables.txt to 60 it still constantly drops to 15-25! I'm going crazy.

Please give some feedback, what's wrong with this game/this machine?

I had this happen to me in a now ancient MMO called EverQuest that I used to play when I was younger. My character would be running along just fine, and then bam instant FPS drops down to 1-5 FPS from the normal. At first I thought it was completely 'random' but I learned that as time went on it would become more frequent, and it would always take the longest to occur when I first turned my computer on and loaded up the game.

So in time I learned that it was my video card overheating. I know you said your temps are good, but take the side of your case off, and put a small floor fan next to it just blowing inside your case.

When I did this all of the frame rate drops stopped happening, and I knew after that that I needed a new video card.

I'm not kidding about this by the way, so don't make fun of my solution please

edit: On the other hand, I'm noticing a lot more people having this problem that just the OP in this thread...so I'm reluctant to think that all of you are having overheating problems, oh well I tried to help.

I've done extensive benchmarks on this issue with CPU/memory/paged pool usage and temperatures for CPU and GPU, and there's no bottleneck to be found.

My CPU is used for about 50% when the drop occurs, and during the drop it doesn't spike or anything, but remains around 50%. Same for memory: about 80% used but it never goes to 100% during the slowdowns. Very strange issue.

The temperature never goes above about 70°, so that's totally acceptable. I'm sure that's not the issue either.

I experience the same, couldn't find any defining aspects about the slowdown until I had a GPU usage monitor open during the occurrence of the problem.

I noticed my GPU usage dropped to 0% when the slowdown occurred.

Full description of the problem as I experience it:
http://us.battle.net/sc2/en/forum/topic/248415154#1

I think determining what would cause the GPU to not even be used (as opposed to being stressed and unable to supply the necessary resources) is key to solving this problem.

I encourage you to get some monitor for your video card either from ATI/Nvidia or the mfg (i.e. EVGA, etc) and check to see if you notice the same thing, otherwise we could be talking about different problems.

Which program did you use to monitor your GPU usage?

EVGA does not appear to be free and I don't want to pay for it...

gpu-z, hardware monitor, everest(I personally use this one for my g15) for monitoring temperatures.

Yeah, I also thought it might be sound related at first, but I have a very good Audiophile card (M Audio Delta). I also tried to use the built in sound card on the motherboard but there was no difference. Disabling sound altogether did nothing either. All research I've done so far points to the older model AMD CPUs. The guy with the intel laptop (or the other guy with intel machines) didn't seem to understand what we were talking about. IT'S NOT JUST FPS DROPS OR UNSTABILITY. The game FREEZES for 5-15 seconds or so (the only real difference from a lockup is that you can move the mouse). Not 1 fps, not 10. zero. What you're talking about is something else. When it doesn't freeze I can run constantly on 60 fps without any drops or unstability. I think this is what we with the AMD San Diego chipset experience. OP might describe a different problem, I'm not too sure.

Anyway I think it's just a quite big bug they haven't cared about or fixed since the beginning of the beta.

Try reverting your drivers back v197.45 and see if that helps. Use driver sweeper before doing that also.

i use msi afterburner. it doesn't allow your gpu to overheat and cease to function.

Kreychek: I checked my GPU usage using EVGA and I get the exact same behaviour. GPU usage actually drops to 0 when the slowdown occurs. It reverts back to about 30% when the slowdown stops. This is definitely the problem. It seems that, for some reason, SC2 stops sending commands to the GPU.

I also checked the heat during this "attack" and it remains constant at about 100°C (this is also the idle temperature - so it's not a overheat issue).

Looks like we're closing in on the issue... Now it's time to figure out how to fix it.

Drivers are having problems with sending data to the gpu and ram right now with certain versions of cards. It sucks even more for people with sli configurations using those cards. It's best to revert back to stable (older) drivers until these issues are fixed especially for older mobile platforms.

We paid $60 for the game and now we have to fix the mess Blizzard has done? Amazing.

Uh...in your case it might be. A GPU idling at 100C is broken. Idle temps should be half that or even less.

It's a 9800 GX2, that's a crossfire card. It's normal that the temperatures are higher than for other cards. And yes, since it is a crossfire card, it is also an SLI configuration.

But I did try multiple versions of drivers, (down to 197.xx) and they all have the same issue. Older drivers actually have it worse. I can of course try to revert to even older drivers, but I doubt that will do any good...

Yes. I already said earlier in this thread that I tried disabling SLI and have the same issues. Besides, the other guy posting the same GPU usage drop doesn't have an SLI card.

Kreychek: I wanted to reply on your bug report, but it's posted on the american battle.net and I have a european SC2 account, so I can't reply. But you can perhaps reply that I have also monitored everything and have the same issue.

My configuration is:

Intel i5 750 quadcore
Geforce 9800 GX2
4GB DDR2 RAM
Asus P7P55D motherboard
Windows 7 64-bit

And if anyone else was still wondering, the program I use is called EVGA Precision, shows GPU usage, video card memory usage, etc. And yeah it's free.

I have the same kind of problem.
I've read a brief comment about that, but still I'd like to ask everybody who was in Beta:
Did you have this problems playing the Beta?
For me the beta worked just fine during the first phase. I never had any problems, no matter what happened on the screen (playing on low). This is my configuration:
+ Show Spoiler +
Pentium T4300 with dual 2,1 Ghz
Geforce G210M
4GB RAM
Windows Vista 32-bit

But when the second phase came along this FPS drops began. Whatever Blizzard fucked up, it was between the two Beta phases.
If a lot of people experienced the same, it should be clear that the problem is caused by SC2.

I didn't encounter any problems during phase 2, but I didn't play that much either so it's quite possible that I just didn't notice.

This happened to me when my 9800GX2 was being throttled due to it getting up to ~115°C...
I cleaned out the card and problem solved.

This happens to me a lot, some days it makes the game unplayable. Even if I turn all settings to low and get an average FPS ov 120, every 10 to 15 seconds it rockets down to 5 fps and up again. It makes it totally unplayable and frustrating as hell.

IMO i think that the engine in SC2 is just poorly optimized as of yet. i mean compared to some other games, it's pretty damn scalable graphically, would that have something to do with performance optimization being funky? i mean c'mon, i can max out Crysis, Mafia 2, GTA 4, and World in Conflict all at good framerates @ 1920x1080, SC2 should be smooth as butter.

something to check, in bios on plug and play os, flip that on and off to see if the issue is fixed, sometimes when you turn it off you will not boot though, it lets windows do irq assignments when on, I prefer main board todo it when off, in order to boot with it off you may have to reload machine with it off.

irq conflics make machine stutter and it happens alot in plug n play is on in the bios
