Uncharted 4 Avx2 Fix

After extensive testing by community members on platforms like Reddit (r/OldPCGaming, r/UnchartedPC), GitHub, and the Steam Discussions, two primary fixes have emerged. Method 1 is safer; Method 2 is more powerful but carries risks.

If you are sitting on a vintage gaming rig—perhaps an overclocked i7-2600K or a salvaged Mac Pro with dual Xeons—you can play Uncharted 4 on PC. It is not a myth. uncharted 4 avx2 fix

However, you must accept that you are running an unsupported workaround. Tweak the settings: turn Texture Filtering to Low, Shadows to Medium, and Reflections to Off. These settings disproportionately use AVX2 math.

Naughty Dog won't patch it. Your motherboard manufacturer won't add AVX2 via BIOS. So, grab the community DLL, add your antivirus exclusion, and prepare to finally sail away from that island prison on an old, unsupported CPU.

Nathan Drake would approve of this hack.

The AVX2 "fix" for Uncharted: Legacy of Thieves Collection (which includes Uncharted 4

) refers to an official update (Patch 3 / v1.3) released on November 16, 2022. This patch added support for older CPUs that lack the AVX2 instruction set—specifically targeting processors older than Intel's 4th Generation (Haswell) or AMD's Ryzen series. Key Takeaways from Community Reviews How it Works

: The game now detects if a CPU supports AVX2. If it does not, it automatically switches to a "fallback" executable (

). This allows older chips like the Intel Sandy Bridge (i7-2600K) or Ivy Bridge (i7-3770K) to run the game. Performance Impact

: Users with older hardware report that while the game now launches, performance can be a mixed bag. Some users on 10-year-old CPUs found it "smooth as butter" or "playable" at 60 FPS, while others noted that shaders still cause high CPU temperatures and potential micro-stutters if not fully compiled. No Impact on Modern PCs

: The fix is designed so that users with modern, AVX2-capable CPUs still benefit from the optimized AVX2 instruction path without any performance degradation. Community Feedback Update Windows, drivers, and runtime libraries

User sentiment is generally positive because the requirement was seen as an unnecessary technical barrier for a game originally built for the PS4 (which did not require AVX2).

“they recently released an update that made the game run on my shitty cpu :), i suggest you update the repack and it might work for you too.”

Nathan Drake stood on the edge of the cliff, staring at the Libertalia ruins—but for

, 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.

The community forums were a battlefield. Half the users told him his "dinosaur hardware" belonged in a museum, while the other half shared cryptic links to unofficial fix patches. Leo wasn't ready to retire his rig. He spent hours scouring threads, downloading a specialized tool designed to emulate the missing instructions. "One more try, Nate," he whispered.

He launched the game using a modified executable—the legendary AVX2 fix. Suddenly, the screen didn't go black. The "Naughty Dog" logo appeared, smooth and steady. He watched as Nathan Drake finally moved, swinging across the jungle canopy at a playable frame rate. It wasn't perfect—the shaders took an eternity to compile—but the treasure of Henry Avery was finally within reach.

Leo leaned back, a small smirk on his face. He hadn't just saved Nathan Drake ; he had saved his own piece of history.

If you are trying to run Uncharted 4: A Thief’s End (or the Legacy of Thieves Collection) on an older PC and experiencing an instant crash on launch, a black screen, or an error mentioning "unsupported instruction," you are likely running into the AVX2 requirement.

This post will explain what AVX2 is, why Naughty Dog’s PC port demands it, and—most importantly—how to bypass it.

Before attempting workarounds, ensure your CPU actually supports AVX2.

If your hardware is below these specs, the official stance from the developers is that your system does not meet the minimum requirements. However, the community has developed workarounds.

Within 72 hours of the game’s release, a Russian modder on GitHub released a custom version.dll or winmm.dll proxy. This method is cleaner than SDE because it patches the game’s import table to skip the AVX2 check entirely.

How to apply the community AVX2 fix:

Why this is better than SDE:

The risk: Antivirus software hates DLL injection. You will likely need to add an exception to Windows Defender. Furthermore, online features (if any remain) may flag this as a modified executable, though Uncharted 4 is single-player.

Since mid-2024, a dedicated modder released "Uncharted4_AVX2_Bypass" – a wrapper that intercepts and emulates AVX2 instructions using software fallbacks.

Step-by-step:

Note: Expect a 10–20% performance drop on very old CPUs. The game will be playable but may stutter during heavy physics scenes.
