Starcraft II Heart of the Swarm PC Crashes, Crash to Desktop, Low FPS, Error Codes and Fixes

The Queen of Blades is gone. On the hellish planet Char, Jim Raynor harnessed the power of an ancient Xel’Naga artifact in a desperate bid to stop the zerg Swarm from overrunning the Koprulu sector, and the artifact restored Sarah Kerrigan to her human form. Without their queen to guide and unify them, the Swarm has fractured into several broods scattered throughout the Koprulu sector.
