I've noticed something strange while playing various games. My laptop will hang briefly (2-3 seconds) every so often while I play games. It's running fine, hangs briefly, then continues going fine again for a few minutes, repeats.
I seem to notice it most when I activate something in a game or trigger an encounter with something (say for example triggering an interaction with an NPC).
I have noticed this in three completely random games so far.
Killing Floor (Steam)
Diablo 3 Beta
Warcraft III & Warcraft III: The Frozen Throne
I have switchable graphics on the laptop and all games are set to "High Performance". Games look spectacular and run fine for the most part minus the hang.
I originally thought it was a memory issue but I just upgraded to 8GB from 4 and just installed Killing Floor (not a taxing game exactly...) and I am getting the hangs in this game.
Computer specs are as follows:
i5 2430M 2.4 GHz
Switchable Graphics - 2GB AMD Radeon HD 6650M
Windows 7 Home Premium x64
