Starcraft 2 Slowdowns

Last response: in CPUs

February 15, 2011 12:54:11 AM

A friend of mine showed me SC2 and I got into it.
But lately I've had some shuddering once in awhile and I can't help but think it's my CPU and/or RAM

CPU: Phenom x4 965 @3.84Ghz
GPU: GTX 580 925/1850/2250
RAM: 4Gbs DDR3 @ 1800

It could be my OC on my RAM + CPU are unstable but it doesn't crash or anything...
I can't help but think my FPS should stay over 45-50 even in huge battles with my setup but it somehow dips to ~25
I'll be waiting for Ivy Bridge until then...

The thing that first comes to mind is sufficient cooling, which without it, can cause major slow downs once it reaches a certain temperature. My suggestion, use Speedfan and find out just where your thermals reach before, during, and at the peak of gaming. That should be a good reference for us to know whether or not its a heating/cooling issue!

Well if cooling is the issue I can just set the clocks to stock, and even that should run it very well.
But nevertheless I will get on that and report back.

Tweak its profile.

What resolutions do you play at?

Defrag your hdd. Clean your junk folders out. Do a chkdsk /r.

Check you security software

Junk is cleaned, security software is fine.

Resolution is 1920x1080
I can go Defrag but I doubt that could lead to such losses.

If I had 1000$ laying around I would xD

But I don't like monitors over 23" so that isn't the best idea anyway.

Dadiggle, what you are telling him to do is irrelevant and non-sensical. If his hardware is slowing down, why on Earth would you give it more work? Also, the way you talk about resolution, you must not know that resolution is capped off by your monitor, it doesn't matter if you have the best graphics card in the world but have amonitor capable of only 1920x1080., the highest it will go is 1920x1080. Anyways, @sowexly, please let me know of you have any theories or have the data on the heat outpu t yet. :)

GTX 580 and 4 GB of RAM? Ugh...

I believe the point he was getting at was the resolution I'm playing at has more to do with my CPU then my GPU and if I increase my resolution it might be better off.

I got the temps back and the max on my CPU was 61 C and my card at 79 C so that is still safe.
What about my ram? I don't know of any games that would perform better with more then 4GBs of RAM so more of it would be a waste.

Starcraft II is very CPU dependent like most RTS games, when in big battles im not surprised things slow down, what you can do to aleviate it a bit is turn down the effects, reflections, and physics as those are more CPU based than GPU based.

Not sure how he figures boosting the resolution will improve the situation, the GPU will be under heavier load but you are still restricted to the number of frames that the CPU can pump out, if it can only pump out 25 in a heavy battle things arent going to improve when you add in a bit more graphics work for it too.

Well after maxing out the work load for my 580, I get about 5 FPS all the time...
This is at 99% load too.

So for what it's worth I don't think that helped the situation at all...

50----------->25fps Thats a bottleneck somewhere. Thats a big drop. Did you try Nhancer

Yes, but cranking up the AA and such just stuck my FPS at 5

The lower the AA and the resolutiion the faster it'll go!

First update drivers for your 580.

Then make sure that Vsync is Off.

I have the 955 black and crossfire 4850s and in a 4v4 massive battle i still get 20. In 1v1s in a 200/200 pop battle im at 45ish so your processor can certainly handle it. It almost certainly has to be a driver issue of some sort, that and the fact that in general AMD boards hate nvidia cards.

Charts posted without settings listed are absolutely meaningless. I dont know if thats on low at 1280x1024, or if its on ultra high at 2560x1600 therefore, its totally meaningless.

Uh huh, now where was i supposed to find that if i hadnt asked? Guess i wasnt. Be nice, post a link to the review when you post those pictures so that i can tell that they excessively biased it towards the CPU.

ANYWAY....


The point is its not with his CPU. the 965 BE even at stock speeds is more than capable of running sc2 at 1920x1080 on ultra considering he has a 580. It has to be a driver/compatibility issue.

Playing MW2 and my FPS spikes too, this has to be some type of driver problem.

I cleaned out my old display drivers, this shouldn't be the problem...

Have you tried changing the Physx setting on the NVDIA control panel? Manually set this to run on the GPU, this will take the load off the CPU as nearly all CPU's are crap at physx given the type of processing it is.

Also look for Starcraft 2 under listed games, it will optimise its self to the game.

you could try setting your RAM to stock speeds as a recent article in Custom PC showed that the difference between your average 1066mhz ram and 1600mhz ram was almost negligible. Unless you have loads of big images files etc.. open fast ram wont have much impact on gaming.

Given your set-up you should be eating the game alive!

Let me know how you get on..

Well I don't see how Starcraft 2 is a PhysX title but I already had my card set to do all my PhysX operations.

Turns out I do destroy the game, but only when I'm host...
I was just used to playing with a buddy but when I go solo it runs at a smooth 80 or so FPS.

No idea how playing it online could do that to my FPS, I mean ping sure but that...
