: Naughty Dog and Iron Galaxy released an official update that specifically addresses the AVX2 requirement, allowing the game to run on older CPUs that only support AVX (like Intel Sandy Bridge and Ivy Bridge). Steam/Epic Games
: Ensure your game is updated to at least Version 1.3.20812 or later.
If you are running an archival, unpatched release of the game or if you are managing a specialized offline installation, you may still run into the AVX2 crash. In these scenarios, the gaming community has documented two primary manual workarounds. Method 1: Using Intel Software Development Emulator (SDE)
To understand the weight of this fix, one must first understand the technical hurdle. AVX2 (Advanced Vector Extensions 2) is an instruction set that debuted with Intel’s Haswell processors in 2013. It allows the CPU to handle heavy floating-point calculations more efficiently, which is crucial for physics simulations and complex AI behaviors—both staples of Uncharted 4 ’s gameplay. By compiling the game with AVX2 instructions hardcoded, the developers at Naughty Dog and Iron Galaxy effectively raised the floor for system requirements. While this decision streamlined performance for modern systems, it alienated users with CPUs that predated 2013, or certain low-budget processors that lacked AVX2 support. For these users, the game would crash immediately upon startup, not because their hardware lacked raw power, but because it lacked a specific vocabulary of instructions. uncharted 4 avx2 fix new
To Nate, this wasn't just a technical glitch. It felt like a locked door in one of Henry Avery's ruins. His computer was a relic, a veteran of a hundred digital wars, powered by an old i7 processor that had seen better days. It didn't speak the modern "language" of AVX2, a specialized shorthand for math that newer chips used to run faster. Because his CPU couldn't understand those specific commands, the game simply refused to exist.
The porting studio, Iron Galaxy, utilized AVX2 instructions to optimize performance for modern hardware. However, because the game checked for AVX2 strictly at startup, CPUs lacking this feature were immediately locked out, causing an instant application crash. Affected Hardware
If you're using a very old CPU (e.g., Intel 2nd or 3rd gen), you may face another limitation: although the game can now launch, performance may still be below expectations even with the AVX2 fix. For those hardware configurations, reducing in‑game settings and waiting for full shader compilation can help improve frame rates. : Naughty Dog and Iron Galaxy released an
During the initial PC port development of Uncharted 4 , the compiler was strictly locked to modern CPU architectures. If a user attempted to launch the game on an older desktop or server-grade processor (such as popular Intel Xeon E5 chips), the operating system could not translate the instructions, leading to immediate desktop crashes upon startup.
