Hello folks,
today I wanted to play some Starcraft II after a longer period of not playing any (I think I started it 2 months ago for the last time..)
Somehow it did not go smoothly at all. After playing a custom game with my buddy, I tabbed out of the Menu to check on CPU-usage just to see that all my cores were up at constant 100% usage, the SC2.exe-process taking at least 89% of the capacity. The last time I was playing, it never went any higher than 30% if I remember correctly (I used to play on all ultra apart from a couple of too flashy things). Also I am experiencing heavy delay while ingame (~1-2 seconds), the CPU-usage drops to 60% once ingame, tho. It should be a lot lower tho, I guess.
I tried lowering the settings quite a bit, but that didn't help at all.
Any help would be highly appreciated !

My specs are:
CPU: i5 quad
graphics card: ATI Radeon 5770
RAM: 8gb
reolution: 1680x1050 (32bit at 60hz)

or in detail:
Operating System: Windows 7 Professional 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.120830-0333)
System Manufacturer: Gigabyte Technology Co., Ltd.
System Model: P55A-UD3
BIOS: Award Modular BIOS v6.00PG
Processor: Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz (4 CPUs), ~2.7GHz
Memory: 8192MB RAM
Available OS Memory: 8188MB RAM
Page File: 2997MB used, 13375MB available

Graphics card+display:
Card name:
ATI Radeon HD 5700 Series
Manufacturer: Advanced Micro Devices, Inc.
Chip type: AMD Radeon Graphics Processor (0x68B8)
DAC type: Internal DAC(400MHz)
Display Memory: 752 MB

I will be glad to provide any info that could be useful to resolve this issue. Thanks in advance !

Might sound a bit dumb, but since there is a new patch all your settings have been changed, check them out.
It's good to be back

Already did that, but sadly did not change anything.. : /

The thing that I really dont understand is: I think my PC should be able to run SC2 easily. At least the recommended settings are all ultra/extreme. Still currently I'm running all settings on low to high. I am experiencing heavy delay ingame (~1 second of command input to execution).
My CPU-Usage seems to only be at 100% when I'm in the menues tho. Ingame it drops to ~60% which still is extremely high, I guess.

Are your CPU/GPU clock at its regular rates when SC2 is running?

i have the same CPU as you do, and yesterday, after a clean install, it was also pulling 100% CPU load. I've retweeked the settings to Medium~low Hybrid, and the FPS jumped up to 160.
However I have a better GPU(6870), but only 6Gb of RAM.

Try to tweak those settings the best you can, because since the last patch, many people are complaining about a lof of FPS issues.
It's all about the reflections of freedom. Even though he hoped for a better world, with all his strenght, all his will, the most he could do was to make her smile.

How can I check on that?

I will try playing a bit more with ingame settings then.

I have an i5 760 and have had same problem a couple of times, it even makes the menu lag horribly.

I just restart SC2 a couple of times and it fixes it.
