Ok guys, I've been searching the Internet and on Lenovo forums I've found a solution to our issue. It appears that Battlefield: BC2 and Skyrim had the same problems and there is a program that can fix this.
I have Intel i7-2670QM, GF GT555M and 8GB RAM and managed to get my FPS back to stable 60 (even 62) at low settings.
First, what causes the issue is pretty much the same thing that was causing nVidia 8 and 9 series graphics card to boil. The upgraded engine in 1.5.0 forces Intel Core processors to work at 100% or more even if it is not required. Because of that, the processor tends to enter the "safe mode" which makes it drop down to 800Mhz for a while and cause a drastic framerate drop.
Now, how to fix this. You have to download ThrottleStop 4.0.0 from this site:
http://www.techinferno.com/downloads/
Then you set it up as following*:

This should help most of you. If the problem persists it means that there's also something wrong with your graphics card. What you have to do is to clean up all the components of your graphics card drivers in Windows' Safe Mode and then install the newest version. If it also doesn't work, then you have to wait for Blizzard to come up with something.
*Note that this is the optimal setting for i7-2670QM processor. If you have worse model, you may have to increase the multiplier ratio in order to get stable 60 FPS.

| Is changing the Multiplier some kind of overclocking or whats the point in doing that? |

Changing the Multiplier is the way to overclock something yes. I don't think it's the safest way to fix that kind of problems. Waiting for a patch/hotfix may be better for our computers : ). |

I wouldn't recommend touching the multiplier unless you know what you're doing and how much money you are risking. Most overclockers only touch the FSB speed and lower the voltage a bit.
As for throttle management, couldn't you do all that with the Power Management tools in Windows? There's nothing wrong with a cpu utilizing 100% of its resources as long as you have an adequate cooling implementation. Simply disable cpu usage throttling if you know your cooling is good enough. |

I've been having FPS drops and believe this is the problem. I changed my variables.txt back to original low and removed shadows. Zerglings are monsters in mass! If they engage in the open, I can't forcefield them at all. And carriers slow me down to 3fps! Yeesh!
I hope blizzard focuses on the FPS problems. |

| Would this have anything to do with FPS spikes? Because other than that im always like 200 + FPS.. |

I was having FPS problems (going between 20-40) and my solution was just update graphics card drivers and problem is gone.
If you haven't updated your graphics card drivers I recommend trying that first, if it doesn't work then I would try this one. |

| Well I don't think I mind enough to try this, but given how we know the reason of the framedrops now it's obvious that it's something blizzard can fix soon, I'll just wait for 1.5.1 to play starcraft again. |

| My lag cleared up by enforcing the CPU to use 100% of its capabilities at all times. If I don't do this, sometimes the CPU will scale back (power saving I guess) and cause me to lag for a very short burst if it suddenly needs the full CPU for whatever is going on in the game. |

| I don't think this has anything to do with the fps drops for other people since sc2 only uses 2 cores and isn't able to max your CPU out to the point where it throttles itself down. It's just a problem with the graphics engine "improvement" that blizzard made and should be fixed in the next patch. |

I wouldnt touch this for many reasons and that goes double if you have no idea what your doing when it comes to O/Cing.
Please just wait for a patch if you have this problem. |

Is there an easy way to set variables.txt to the original low? what parts of it do you have to change to do this? I'd like to use this solution if possible.Last edit: 2012-08-07 02:22:07 |

ya, this prob depends on your system etc... but to get the variables.txt i press start, then click on documents, then click on starcraft2, and you'll see a notepad file called variables.txt beneath some folders.
to get original low set alternatelowtextures to =0. it will be equals 1 when you get there. just replace the the 1 with the 0. it's organized alphabetically so it will be near the top. |

With O/C it is very simple : If you dont know what you are doing, DONT do it! If you really need/want to overclock, make an effort and understand it first before you do anything.
And please dont trust people who tell you stuff like "with the i7-xxxx you should set value x to y". There is no such thing as two identical cpusLast edit: 2012-08-07 03:14:30 |

Wait a sec.
Are you 100% sure what are you talking about?
Latelly i'm only playing sesions of 3-4 games, so i never experienced any mayor slowdown besides the overall slower performance (loggin, loading, menues and such).
Are the desktop versions of Intel sandy bridge procesors suffering from this too?
I mean, in case that this is really happening to all core i3, i5, and i7, this is an insanely MAYOR ISSUE with 1.5. |

It's Underclocking, not Overclocking. It worked for thousands of people with both BFBC2 and Skyrim, now I've tried it out and realized that it works for SC2 as well. If it works for me, I wanted to share this and maybe help some other people. And as I said, there is no risk of overheating, since it's not overclocking. You can't set value higher than the "standard", you can only turn down the clock. The problem is that SC2 automatically controls the CPUs work and the games engine has a hole which makes the CPU malfunction. This program blocks SC2 from controlling the CPU.
EDIT:// @Belha - To my knowledge the issue is only touching the Mobile versions of Sandy Bridge. Desktop models are propably working good. It is like that because the mobile versions for notebooks have other BIOS than desktop versions, and it has a conflict with SC2.
Also, I have to agree with people saying that if you don't know what you're doing, don't do it. You may wait for Blizzard to fix this, but it may take a long time. This is a temporary fix, I've played ~15 games in a row and it worked, don't know how will it do in the long run, but looking at the previous experiences of Skyrim and BFBC2 players there won't be any problems.Last edit: 2012-08-07 03:31:07 |

I'm not holding my breath on a patch for this as D3 has had the EXACT same problems since fking beta. The problem isn't related to CPU being throttled though, at least for me and most other people. The problem is with loading a new asset for the first time, and this is apparently something that has to be done every time you restart the damn program. It's a caching issue, and Blizzard finally admitted yesterday that they are aware of it.Last edit: 2012-08-07 04:10:13 |
