Aside from the previous fix I posted, I have another fix for the in-game lag in StarCraft 2. The lag could be caused by the GPU rendering the frames at max speed which might cause the video card to overheat and slow down the game.
The following will help by telling StarCraft 2 to limit the behavior:
- Open My Documents\StarCraft II Beta\variables.txt using Notepad (or any other text editor)
- Add the following two lines to the file:
- Save the txt file and you’re done.
The frameratecapglue variable controls menu screens framerates. The frameratecap controls the in-game framerate. I have chosen 60 as I am running this game on a laptop (60 is the max refresh rate for my monitor) but you can choose any number that fits your configuration.
