: Before making changes, copy your original u4.exe and tll.exe files to a safe folder.
If you dual-boot or use Steam Deck (older CPU? unlikely), you can run the Windows version through .
Extract the contents directly into your main Uncharted 4 installation directory (where u4.exe is located).
Early versions of Uncharted: Legacy of Thieves Collection had strict AVX2 requirements. However, according to early community reports 1.2.2 , updates, specifically around Patch 1.3, helped improve compatibility for some users. Verify that Uncharted is updated to the latest version. uncharted 4 avx2 fix
The search for an Uncharted 4 AVX2 fix became a digital scavenger hunt typical of the PC gaming ecosystem. Unlike a standard bug which requires a developer patch, an instruction set incompatibility is a fundamental architectural mismatch. The "fix" isn't a simple settings toggle; it usually involves an emulator or a CPU patch that intercepts these illegal instructions.
On process start, the fix checks cpuid directly (bypassing potential anti-hook). If AVX2 is absent, it overwrites the game’s code section with fallback sequences. If AVX2 is present, it leaves the original instructions but still hooks CPUID to avoid potential detection.

The most reliable "fix" is simply to update your game. On , developers Iron Galaxy and Naughty Dog released Version 1.3.20812 , which officially added support for non-AVX2 CPUs.
Intel Core i7-3770, i5-3570 (and older Sandy Bridge/Ivy Bridge) Earlier AMD FX/Phenom II processors. 1. The Primary Fix: Update to the Latest Game Patch
Uncharted 4: A Thief's End is a masterpiece of cinematic gaming, but for players on older or budget-friendly CPUs, the PC port launched with a frustrating barrier: the AVX2 instruction set requirement. If your processor doesn't support AVX2, the game simply crashes on startup or refuses to launch. Extract the contents directly into your main Uncharted
Uncharted: Legacy of Thieves Collection brought the cinematic action of Nathan Drake to PC, but many users with perfectly capable, yet slightly older processors were met with instant crashes or refusal to launch. The culprit?
If you are trying to run the game on a CPU that doesn't support the AVX2 instruction set (like older Intel Core i5/i7 "Sandy Bridge" or "Ivy Bridge" processors), the game simply won't launch. But don't worry—you don't necessarily need to buy a new PC. In this guide, we will explain why this happens and the current methods to fix the Uncharted 4 AVX2 issue.
Intel’s (Software Development Emulator) can emulate AVX2 on older CPUs.
A "proper" feature-level fix involves creating a that intercepts the illegal instructions and emulates them or redirects them to compatible code paths. 1. Identify the Entry Point
