Right-click ExtremeInjector.exe and select . Click on the Add DLL button in the injector interface. Browse and select the downloaded DualCore.dll file.
Even with the fix, performance may be poor. Users often use Task Manager to "Set Affinity" and ensure the game isn't overloaded on a single thread.

~90% on modern dual-cores with Windows 10/11.
When running a standard dual-core processor (such as older Intel Celeron, Pentium, or basic AMD chips) that lacks Hyper-Threading, Thread 3 does not exist. Instead of dynamically adapting to your hardware or displaying an error message, the game engine enters an infinite loop waiting for that fourth core to respond. This manifests as a frozen black screen or an immediate crash. What is Extreme Injector? Far Cry 4 Dual Core Fix Extreme Injector

When Far Cry 4 launched, thousands of PC players encountered a frustrating issue: launching the game resulted in a permanent black screen that immediately crashed to the desktop. The culprit was Ubisoft’s strict engine requirement for a native quad-core processor. Dual-core CPUs—even high-performing ones with hyper-threading like the Intel Core i3 or Pentium series—were locked out entirely.
However, The dangers of malware infection, the questionable legitimacy of the source files, and the inconsistent results on modern systems make it an option that should only be considered by advanced users who fully understand the potential consequences.

Far Cry 4 was notorious at launch for a specific technical limitation: it would not run on computers with dual-core processors. Because the game engine was designed to utilize four threads, players with older or budget CPUs—like the Intel Pentium or Core i3 series—were met with a persistent black screen upon startup.
: Manually disabling specific threads in Task Manager or using tools like Process Lasso to force the game to run on specific cores. Low Specs Experience
Because injectors modify running memory processes, antivirus programs mistake them for malicious software. Add the entire Far Cry 4 directory to your antivirus exclusion list.
Q: How do I uninstall the Extreme Injector patch? A: To uninstall the patch, simply run Extreme Injector, select Far Cry 4, and click the "Uninject" button. This will remove the patch and restore the game's original code. Even with the fix, performance may be poor
While the concept of DLL injection is not inherently malicious,
Far Cry 4 runs on the Dunia Engine 2 (a heavily modified version of CryEngine). At startup, the engine runs a thread affinity check. In simple terms, it says: “I need four hardware threads to manage AI, physics, rendering, and audio simultaneously. If you don’t have four, I will hang.”
Fortunately, the PC gaming community quickly engineered a workaround. By using a community-made dual-core fix alongside a tool called Extreme Injector, players could bypass this hardware check and run the game smoothly. This article explains exactly how the fix works, how to install it safely, and how to troubleshoot common issues. Why Far Cry 4 Crashes on Dual-Core CPUs
