The solution involves using the Extreme Injector to inject a custom DLL (Dynamic Link Library) that modifies the game's behavior to better support dual-core processors. This DLL essentially tricks the game into thinking it's running on a quad-core processor, allowing it to utilize the dual-core CPU more efficiently.
Far Cry 4 was designed to require at least a quad-core processor. On systems with dual-core CPUs (like older Intel Pentium or Core 2 Duo models), the game engine fails to load properly, resulting in a permanent black screen at launch. The fix works by injecting a specific library ( dualcore.dll ) into the game process to emulate the missing cores or manage thread allocation. Far Cry 4 Dual Core Fix Extreme Injector
