Blizzard has confirmed that there is an overheating problem with ‘StarCraft II” that might melt your desktop. The problem has been identified to be that certain screens in “StarCraft II” will make your computer work twice as hard.
Usually, you would think that a screen with a lot of details would overheat your computer, but this time is the screens with less details that are the culprit. Screens with less details are said to cause the game to idle and just primarily draw the screen at a very fast pace which leads to overheating your computer if you do not have a very good cooling system.
Certain screens make your hardware work pretty hard
Screens that are light on detail may make your system overheat if cooling is overall insufficient. This is because the game has nothing to do so it is primarily just working on drawing the screen very quickly. A temporary workaround is to go to your Documents\StarCraft II Beta\variables.txt file and add these lines:
You may replace these numbers if you want to.
User report – Security program flagging the beta downloader as a trojan
We had some reports where a security program might flag the beta downloader as a trojan. It is a false positive.
Also, there are other problems reported such as Black Screens and the Compatibility Mode is not working properly. We should see an update soon from Blizzard to address these problems.
There have been multiple reports of black screen issues being related to the use of a Quick Cam webcam.
In some cases exiting out of the software has resolved the issue but others have reported a need to uninstall the software for the camera in order to resolve the problem.
There are also reports where some security programs like Comodo firewall can cause the game to start and stay on a black screen.
Compatibility Modes will not work properly
Attempting to run StarCraft 2 on a compatibility mode (Windows XP SP3 from Windows 7, for example) will make it crash. Please run the game normally.
