Uncharted 4 Avx2 Fix New -
Initially, only a CPU emulator or binary patching worked.
Now, thanks to community patches (from CS.RIN.RU or Reddit), there are modified EXE files or DLL wrappers that skip AVX2 checks or emulate the instructions.
⚠️ Important:
These fixes are unofficial and may:
For months, a silent frustration has plagued a subset of PC gamers. You downloaded the colossal 126GB masterpiece that is Uncharted 4: Legacy of Thieves Collection. You met the GPU requirements. You had enough RAM. Yet, every time you hit “Play,” the screen flashed black for a second, or an error log appeared citing an illegal instruction. The culprit? AVX2.
If you are the owner of an older but still capable CPU (like Intel’s Sandy Bridge, Ivy Bridge, or first-gen Ryzen without AVX2), you have been locked out of Nathan Drake’s final adventure. Until now.
A new wave of community-driven fixes has emerged in late 2024 and early 2025. This article details everything you need to know about the new Uncharted 4 AVX2 workarounds, why Sony’s port relies on this instruction set, and—most importantly—how to get the game running on your legacy hardware today.
If a hardware upgrade isn't feasible, consider playing Uncharted 4 on a different platform. Uncharted: The Nathan Drake Collection and Uncharted 4: A Thief’s End are available on PlayStation consoles.
Navigate to your Uncharted 4 installation folder (e.g., Steam\steamapps\common\Uncharted 4).
Before attempting to fix the issue, it's essential to verify whether your processor supports AVX2. You can use tools like:
1. The game still crashes:
For players using older hardware, the initial launch of Uncharted: Legacy of Thieves Collection on PC was frustrating due to a strict requirement for AVX2 instruction sets. This blocked owners of popular older CPUs—like the Intel Sandy Bridge (i7-2600K) or Ivy Bridge series—from even launching the game. uncharted 4 avx2 fix new
Fortunately, official and community solutions now allow these "legacy" processors to run the game effectively. The Official "New" Fix: Native Non-AVX2 Support
The most reliable "fix" is now built directly into the game. On November 16, 2022, developer Iron Galaxy released a major update (Patch 1.3.20812) that officially removed the AVX2 restriction.
Automatic Fallback: If the game detects a CPU without AVX2 support, it automatically switches to a fallback executable: u4-l.exe (for Uncharted 4) or tll-l.exe (for The Lost Legacy).
Performance Benefits: This method ensures that users with modern CPUs still benefit from AVX2 optimizations while older hardware can still run the game without external "hacks".
How to Apply: Simply update your game to the latest version via Steam or the Epic Games Store. Alternative Community Fix: Intel SDE Emulator
If you are running a version of the game that precedes the official patch, or if you encounter issues with the official fallback, the community developed a workaround using the Intel Software Development Emulator (SDE).
How it Works: The emulator intercepts AVX2 instructions and translates them into standard instructions your older CPU can understand. The Process: Download the Intel SDE tool. Create a desktop shortcut for sde.exe.
Modify the shortcut's "Target" properties to include -hsw -- [GameExecutableName].exe.
Warning: This method is an emulation layer and typically results in extremely poor performance, often described as a "20 FPS slideshow". Minimum System Requirements Refresher Initially, only a CPU emulator or binary patching worked
Even with the AVX2 requirement removed, the game remains demanding. To play at 720p/30 FPS on "Medium" settings, you generally need:
Here’s a short, useful story framed as a troubleshooting guide for someone searching for an "Uncharted 4 AVX2 fix new" — told from the perspective of a gamer who solved it.
Title: The Lost Legacy of AVX2
Context:
You’ve just downloaded Uncharted 4: Legacy of Thieves Collection on PC. You meet the requirements — almost. Your older CPU (e.g., Intel 3rd/4th Gen or an early AMD FX) lacks AVX2 instructions. The game crashes on launch with a silent exit or an error about “unsupported instruction.”
The Story:
Leo, a budget gamer with an i7-4770 (no AVX2), faced the same wall. Every forum said: “Buy a new CPU.” But he found a working path in late 2024–2025.
Step 1 – The False Hope
Leo first tried old “AVX emulators” or generic DLL patches. They either failed or triggered anti-cheat (even in single-player). Don’t waste time here.
Step 2 – The Real Fix (New Method)
He discovered a CPU emulation layer called SdeMirror (based on Intel’s Software Development Emulator). Unlike old hacks, this wraps only the AVX2 instructions without tanking performance.
Result: The game launched! But at ~20 FPS — unplayable. For months, a silent frustration has plagued a
Step 3 – The “New” Optimization Trick
Leo found a refined script from a GitHub user “AVX2Patch” (updated Jan 2025). Instead of emulating all instructions, it used selective emulation + a Vulkan wrapper to reduce overhead.
Step 4 – The Working Combo (as of 2025)
Leo’s final setup:
The Payoff:
Uncharted 4 ran at 30–45 FPS — stable, no crashes. Leo played through “Madagascar” without a single AVX2 error.
Takeaway for you:
Final note from Leo:
“The jungle chase scene at 30 fps on a 10-year-old CPU felt like a miracle. But honestly? If you love the game, start saving for a Ryzen 5 — the emulation stutters during explosions.”

⚠️ Warning: Avoid downloading any "AVX2 fix" executables from random forums or YouTube videos. They are almost always viruses, cryptominers, or info-stealers targeting gamers.
If you saw a recent "new" AVX2 fix for Uncharted 4 on Reddit or elsewhere, it is fake. No legitimate patch has ever been released to bypass this requirement.
This is a deep guide on fixing the AVX2 (Advanced Vector Extensions 2) crash in Uncharted: Legacy of Thieves Collection (specifically Uncharted 4) on PC.
This issue typically occurs because the game's executable requires a CPU instruction set (AVX2) that older CPUs (like 1st/2nd/3rd Gen Intel Core i3/i5/i7 or older AMD Phenom/FX processors) do not support. When the game hits this instruction, it crashes instantly, usually at the "Loading" screen or startup.
