To understand the allure of the compressed install, one must first understand the technical reality of modern gaming. Call of Duty: Black Ops 3 is a visually complex title, utilizing high-resolution textures, complex audio files, and cinematic cutscenes. These assets require data. When a game is compressed, algorithms shrink file sizes by removing redundant data. However, legitimate compression has limits. When a 100 GB game is reduced to a fraction of its size, it usually implies that the compression is lossy—meaning data is permanently discarded—or that the file has been stripped of essential components, such as multiplayer modes, campaign missions, or high-definition assets. Consequently, the "highly compressed" version is rarely the game as the developers intended it; it is often a hollowed-out shell, suffering from lower visual fidelity, missing audio, and frequent crashes.
