The Uncharted 4 AVX2 error typically occurs when the game tries to use AVX2 instructions, but your CPU doesn't support them. This can cause the game to crash or display an error message. Some common symptoms of the AVX2 error include:

Uncharted 4: A Thief's End, developed by Naughty Dog and published by Sony Interactive Entertainment, is an action-adventure game that has captured the hearts of gamers worldwide. Released in 2016, the game follows the story of Nathan Drake as he searches for a long-lost treasure. With its engaging storyline, stunning visuals, and smooth gameplay, Uncharted 4 has become a classic in the gaming world.

This method allows users with newer CPUs to keep their performance benefits while letting legacy hardware run the game without crashing.

The PC port of Uncharted 4: A Thief's End utilizes the AVX2 (Advanced Vector Extensions 2) instruction set, specifically SIMD (Single Instruction, Multiple Data) operations, for high-performance mathematical calculations. This creates a hard dependency on Intel Haswell (4th Gen) or later, and AMD Ryzen (Zen) or later CPUs. Users attempting to run the title on legacy hardware (e.g., Intel Ivy Bridge or AMD FX series) encounter an immediate EXCEPTION_ILLEGAL_INSTRUCTION (0xC000001D) crash. This paper analyzes the "AVX2 Fix" methodology, which typically involves binary patching or instruction emulation to bypass this hardware requirement.
