Uncharted 4 Avx2 Fix ~repack~ -
For a short time, this rendered the game unplayable on popular budget CPUs and older Intel/AMD processors (such as some Xeon models, older Core i7/i5/i3, and AMD FX series). Fortunately, a definitive fix was released, rendering complex workarounds unnecessary. The Official Solution: Patch 1.3.20812 (November 2022)
Future updates to Uncharted 4 (if any) will likely break both fixes. Block the game from updating via Steam’s “Only update this game when I launch it” setting, and always launch via your .bat file or patched EXE.

If your CPU lacks AVX2 support, the game attempts to execute an instruction your hardware literally does not understand. Instead of lagging, the operating system instantly terminates the application, resulting in a crash to desktop (CTD) with no error message. Affected CPU Generations
If you are running an unpatched version, a backup copy, or playing on an unsupported operating system environment where the official patch still fails, you can use the Intel Software Development Emulator (SDE) method. This tool acts as a translator, converting AVX2 instructions into code your older CPU can read. Step-by-Step Installation
Replace these instructions with a CALL to a custom function. For a short time, this rendered the game
released an official update (Patch 1.3) specifically to address the AVX2 instruction set requirement
Before attempting workarounds, ensure your CPU actually supports AVX2.
This is the most common method used by the community. It involves using a tool created by Intel called the . This tool emulates the AVX2 instructions on older CPUs. Block the game from updating via Steam’s “Only
, developer Iron Galaxy released a significant update (Version 1.3) that officially added support for older CPUs without AVX2. Fallback Executables
About three months after launch, a modder known as on the CS.RIN.RU forums released a patched .exe that removed the AVX2 requirement entirely by hex-editing the compiler checks. This file has since been mirrored on GitHub and Nexus Mods.
Outdated drivers are a frequent cause of crashes and glitches. Download the latest drivers directly from NVIDIA or AMD.
