Uncharted 4 Avx2 Fix [EASY × 2026]

To develop a proper AVX2 fix for Uncharted 4 (Legacy of Thieves Collection)

, sitting in his dimly lit bedroom, the scene was a stuttering mess of frozen pixels and a "Fatal Error". His old PC, powered by a trusty but aging i7-2600K, was gasping for air, unable to understand the game’s AVX2 instruction set.

Performance Note: Modern CPUs still use the standard AVX2 executable to maintain optimal performance, as these instructions help speed up floating-point computations. Manual/Alternative Workarounds uncharted 4 avx2 fix

For a visual walkthrough on applying the official AVX2 compatibility update:

  • Copy the SDE Files: From the Intel SDE folder you extracted, copy the file named sde.exe and the dll files associated with it (specifically sde-dyn.dll and others in the intel_sde subfolder depending on the version). Paste them into the Uncharted 4 game folder mentioned above.
  • Run the Game via Command Line: You cannot just launch the game via Steam. You must launch it through the emulator.

    For owners of high-end hardware from the pre-Haswell era (roughly pre-2013 Intel chips, like the beloved Ivy Bridge i7-3770K or early Xeons), the game would crash immediately upon startup. The executable was hard-coded to utilize AVX2 instructions for processing complex mathematical operations efficiently. If the processor didn't speak that specific dialect of code, the program simply had no fallback language. It was a binary gatekeeper: have AVX2, or play nothing.

    The Official Fix: On November 16, 2022, developer Iron Galaxy released Version 1.3.20812, which officially added support for non-AVX2 CPUs.

    The 3 Viable Solutions (The Real "AVX2 Fix")

    Depending on your technical comfort level, there are three ways to bypass the AVX2 lockout. Warning: These are unofficial workarounds. Proceed at your own risk. Copy the SDE Files: From the Intel SDE

    To resolve the AVX2 requirement in Uncharted: Legacy of Thieves Collection (which includes Uncharted 4), the most reliable solution is to update the game to Patch 3 (v1.3) or later. This official update was specifically released to introduce AVX2 support and allow the game to run on older CPUs that lack this instruction set. Official Fix: Patch 1.3 Update
