While there is no official "AVX2 fix" for Uncharted 4: A Thief's End
on PC, players with older CPUs that lack AVX2 support often use community-made script fixes or bypasses to launch the game. Understanding the AVX2 Requirement
Uncharted 4 and The Lost Legacy (Legacy of Thieves Collection) natively require AVX2 (Advanced Vector Extensions 2) instructions. If your CPU (such as older Intel Core i7-2600K or AMD Phenom series) does not support this, the game will typically crash on startup with an error or fail to open entirely. How to Use a Community AVX2 Fix
Locate a Trusted Repository: Search for the "Uncharted 4 AVX2 Fix" on reputable community hubs like GitHub or Nexus Mods. Avoid "free" download sites that require completing surveys or downloading .exe files from unknown sources, as these are often malware.
Download the DLL/Script: Most fixes consist of a modified physx.dll or a specific launcher script designed to "spoof" or bypass the instruction check.
Backup Original Files: Navigate to your game installation folder (usually SteamLibrary\steamapps\common\Uncharted Legacy of Thieves Collection). Copy the original executable and DLL files to a safe folder before making changes.
Install the Fix: Move the downloaded community files into the main game directory, overwriting the originals if prompted.
Run as Administrator: Right-click the game executable and select "Run as Administrator" to ensure the bypass has the necessary permissions to execute. Risks and Limitations
Performance Stability: Because the game is designed to utilize AVX2 for physics and math calculations, bypassing it can lead to significantly lower frame rates, stuttering, or crashes during heavy action sequences.
Game Updates: Official patches from Naughty Dog or Iron Galaxy may break community fixes, requiring you to wait for an updated version of the fix.
Security: Use caution when downloading "fixes" from unofficial forums. Check user comments and "Endorsements" on Nexus Mods to verify the file is safe.
The story of the Uncharted 4 AVX2 fix is a classic tale of a community overcoming technical hurdles to keep older hardware alive. When the Uncharted: Legacy of Thieves Collection first launched on PC, many users with older but capable CPUs (like Intel's Ivy Bridge or Sandy Bridge series) found they couldn't even open the game because it strictly required the AVX2 instruction set. The Technical Barrier
Initially, the game would crash on startup for anyone without a CPU from roughly 2013 or later. This was frustrating for many players who had hardware that otherwise met the game's performance needs but simply lacked that specific modern instruction. The Community's Workaround
Before an official fix arrived, the "free" community-driven solution involved using "hooks" or unofficial patches to bypass these checks. Enthusiasts shared modified executables and instructions on forums like Reddit and the Steam Community to get the game running on "unsupported" hardware. The Official "Fix" uncharted+4+avx2+fix+free
Recognising the demand, the developers at Iron Galaxy eventually released Patch 3 (v1.3) on November 16, 2022. This update:
Added support for non-AVX2 CPUs: The game now detects older hardware and switches to a "fallback" executable (u4-l.exe or tll-l.exe).
Maintained Performance: Newer CPUs continue to use the AVX2 path to benefit from modern optimisations without being held back by the legacy support.
Resolved Stability: This official patch significantly reduced the crashes and bugs associated with the earlier community-made "fixes". Where to Find It
Uncharted: Legacy of Thieves Collection (which includes Uncharted 4
) originally required CPUs with AVX2 support to launch, the developers officially removed this restriction in Patch 3 (v1.3.20812)

For many PC gamers with older hardware, launching Uncharted 4: A Thief's End (part of the Legacy of Thieves Collection) was met with a frustrating "unsupported CPU" error. This was due to the game's initial requirement for AVX2 (Advanced Vector Extensions 2), a processor instruction set that many older—yet still capable—CPUs like the Intel Sandy Bridge (i7-2600K) or Ivy Bridge (i7-3770K) do not possess.
If you are looking for a way to play Uncharted 4 without AVX2 support, you no longer need to rely on unstable third-party "fix" downloads or external emulators. The Official Fix: Patch 1.3.20812
The most important news for players is that Naughty Dog and Iron Galaxy released an official update on November 16, 2022, specifically to address this issue.
What it does: The patch adds support for older CPUs by detecting the lack of AVX2 and automatically switching to a fallback executable (u4-l.exe for Uncharted 4 or tll-l.exe for Lost Legacy).
How to get it: If you own the game on Steam or the Epic Games Store, simply update your game to the latest version. This official "fix" is free and included in the standard game files. Why You Should Avoid "Free Fix" Downloads
Searching for "Uncharted 4 AVX2 fix free" often leads to sketchy third-party sites offering .exe or .dll files. These are generally not recommended for several reasons:
Safety Risks: Many "free fix" downloads from unverified sources may contain malware or viruses.
Outdated Methods: Before the official patch, users used the Intel Software Development Emulator (SDE) to bypass the check. This method is highly inefficient and often results in unplayable frame rates (around 10–20 FPS) because your CPU has to emulate complex instructions it wasn't built for.
Redundancy: Since the official 1.3 update, these manual workarounds are obsolete for most users. How to Check if Your CPU Supports AVX2
If you are still having trouble launching the game, verify your hardware capabilities:
Intel: AVX2 was introduced with the Haswell (4th Gen) architecture. If your CPU is older (e.g., i7-2600K, i7-3770K), you lack AVX2.
AMD: AVX2 support began with Excavator and Ryzen processors.
Tool: Download CPU-Z to see a list of instructions supported by your processor under the "Instructions" field. System Requirements Overview
Even with the AVX2 restriction removed, Uncharted 4 is a demanding title. Ensure your PC meets the rest of the minimum specs to avoid severe lag:
The most effective way to play Uncharted 4: A Thief's End Legacy of Thieves Collection ) on a CPU that doesn't support is to use an "AVX2 Emulation" or "AVX Fix" wrapper.
Since the game officially requires the AVX2 instruction set, it will usually crash at startup on older CPUs (like 1st-3rd gen Intel Core or older AMD chips). The community-standard solution is the AVX2-Legacy-CPU-Fix (Simple Open Direct Engine) wrapper.

What to expect:
Uncharted 4 on PC was built utilizing AVX2 (Advanced Vector Extensions 2). This is a set of CPU instructions that allows the processor to handle heavy computational tasks more efficiently.
The Problem: While most modern CPUs (Intel Haswell [4th Gen] and newer, AMD Ryzen and newer) support AVX2, older processors—even powerful ones like the Intel Core 2 Quad, older Core i7s (1st–3rd Gen), or AMD FX series—do not support AVX2.
If your CPU lacks this instruction set, the game will usually crash instantly upon launch with no error message, or throw a system exception.
Navigate to your game installation folder. Usually:
C:\Program Files (x86)\Steam\steamapps\common\Uncharted Legacy of Thieves CollectionC:\Program Files\Epic Games\UnchartedLegacyofThievesCollectionInside, find the Uncharted4.exe file (or U4.exe depending on updates). Do not launch it.
As of late 2024, this AVX2 bypass works through the entire main campaign and The Lost Legacy. However, be aware of:
This involves editing the game's executable (binary patching) to replace AVX2 instructions with equivalent AVX (128-bit) instruction sequences.
Instead of running the game directly, we will tell Windows to run the game through the Intel SDE emulator.
Open Notepad.
Paste the following single line of code. Note: You must adjust the paths to match your system.
C:\SDE\sde64.exe -skx -- C:\Games\Uncharted4\Uncharted4.exe
Explanation: -skx is the magic flag. It tells the emulator to enable AVX2 and AVX-512 feature levels. -- separates the emulator command from the game command.
Critical adjustment: Change C:\SDE to where you extracted Intel SDE. Change C:\Games\Uncharted4 to your actual game path.
Save the file as Launch_Uncharted.bat on your Desktop. Ensure "Save as type" is set to "All Files (.)", not ".txt".
