When The Phantom Pain launched, it was lauded for its mechanics but plagued by memory leak issues, crashing, and an unoptimized online infrastructure known as the Forward Operating Bases (FOB). For months, PC players dealt with unpredictable crashes and stuttering. The release of version 1.15 was not merely a routine bug fix; it was the consolidation of the game's stability. It represented the end of the development cycle, a final "gold" state where the developers had addressed the critical memory management issues that caused the game to crash during extended play sessions or intense graphical loads.
