Why am I still lagging in Star Craft II? [closed]

  • 17.3" FULL HD (1920X1080) LED LCD
  • nVIDIA GeForce® GT 425M w/1GB GDDR3
  • Intel GMA HD4500
  • 640m core i7 processor
  • 8 GB RAM
  • 64 bit OS

For some reason, when there is a batle in progress it appears as if my graphics card or something is not powerful enough. Shouldn't these specs be more than enough to handle Starcraft II?

What could I do to improve my laptop?


  1. Make sure you have the latest drivers from NVidia for your primary card.
  2. Make sure the primary card is enabled and is being used, since the onboard Intel card is garbage.

Now, frame rates (FPS) around ~30 is still considered playable. If you are experiencing worse frame rates, that means you are running your quality settings too high. Try running the game on Low or Medium to get better performance. If you are running the Full native resolution of your screen, you will definitely stress your graphics chip in a higher setting.

If you installed the Nvidia drivers properly, I believe Optimus would switch to your Nvidia graphics chip to play games like Starcraft 2. Everything is worse on the Intel chip.
