Starcraft 2 100% CPU Usage??

post #1 of 7
Thread Starter 
Hi

My girlfriend has been playing Starcraft 2 on her PC (E5300 2.6GHz with 4GB DDR3 and 1GB GTS250 running Win7 Home Prem. x64) since it was first released with no problems.

For the past month or so (no sure if its patch related) she's experienced serious FPS drops, especially in the menus.

GPU usage never goes over 80% (vsync on), but her task manager shows SC2 using 95-100% of her CPU all the time...

My sig rig never shows over 10% CPU usage in the SC2 menus. I realise there's a big CPU difference, but seriously? confused.gif

***? Has anyone else had this issue? Has a new patch done something silly?
Any suggestions/help/random guesses would be appreciated.

Thanks.

Extremely large CPU difference - if she is seeing 80% GPU utilization with vsync on it means that both are pretty much at their limits for the settings she is playing on. I would suggest overclocking if possible, it should be able to do 3.4ghz easily which would help to severely alleviate CPU usage - also remember that SC2 can utilize 4 cores, so a dual core is going to take a bit of work.

Fair enough. It's just weird that this wasn't an issue in the past.

Time for an upgrade I guess tongue.gif

As they patch the game things can change. Sc2 can be pretty demanding on the cpu. Make sure you check task manager for anything running in background wasting clock cycles.

Alot of the custom game modes are harder on the cpu.

Last time I checked, SC2 is only optimized for dual cores.

Unless there was a recent patch that made it take advantage of quad cores.

Yup, still won't use more than 2 cores.

Ok so rather an overclock instead of an upgrade...but that's a pretty good rule of thumb anyways applaud.gif


Thanks for the words everyone. OCN continues to be a great hangout.
