The most straightforward solution is to upgrade your CPU to one that supports AVX2. This ensures compatibility with Uncharted 4 and future-proofing for other games and applications.
Best for: Users who cannot find a pre-modded executable or want a "cleaner" method that doesn't permanently alter game files.
Intel SDE is an official tool by Intel that intercepts CPU instructions and emulates them. This is often more stable than a hacked executable but is slightly more complex to set up.
Step 1: Download Intel SDE
Step 2: Prepare the SDE
Step 3: Locate the Game Executable
Step 4: Create a Batch Script Instead of typing commands every time, create a launch script.
Step 5: Play

AVX2 (Advanced Vector Extensions 2) is a set of instructions for x86 processors, designed to handle more data per clock cycle than its predecessor, AVX. It's a part of Intel's Haswell and later processors and AMD's Excavator and later processors. AVX2 enhances performance in floating-point-intensive applications, such as 3D graphics games.
By following this guide, players should be able to address the AVX2 issue and enjoy Uncharted 4. Whether through a hardware upgrade or exploring alternative gaming platforms, there are solutions available to ensure you don’t miss out on Nathan Drake’s epic adventures.
Uncharted 4 (Legacy of Thieves Collection) AVX2 requirement was a major hurdle for players with older CPUs (like Intel Sandy Bridge or Ivy Bridge), initially preventing the game from launching. The Official Fix: Patch 1.3 (v 1.3.20812) On November 16, 2022, developers Iron Galaxy
released a significant update that officially added support for non-AVX2 CPUs. Removal of Restriction
: The patch removed the hard CPU restriction, allowing the game to boot on processors that only support AVX1 (such as the i7-2600K or i7-3770). How it Works The most straightforward solution is to upgrade your
: Discussions suggest the requirement was likely a compiler-level setting rather than a fundamental reliance on the instruction set. The fix involved providing an executable compiled without the AVX2 mandate. Other Improvements
: This same patch included camera fixes for mouse users and improved behavior while strafing in windowed mode. Why was it controversial?
The "AVX2 fix" sparked intense community debate for several reasons: Efficiency vs. Accessibility
: AVX2 instructions act as "accelerators" for math functions. While removing the requirement makes the game accessible, users on older hardware may still experience lower frame rates or stuttering. Legacy Hardware Viability
: Many players pointed out that while their CPUs were "old," they still possessed enough raw power to run modern titles like Elden Ring Spider-Man
, making the Uncharted lockout feel like a "sloppy developer oversight". Unofficial Workarounds
: Before the official patch, the community attempted "fixes" using tools like Intel Software Development Emulator (SDE). However, these resulted in unplayable performance, often hovering between 7–15 FPS. Performance Expectations for Older CPUs

Bridging the Gap: The Technical Necessity and Community Triumph of the Uncharted 4 AVX2 Fix
When Naughty Dog’s Uncharted 4: A Thief’s End made its long-anticipated debut on PC, it was viewed as a milestone for the storied franchise. For years, the adventures of Nathan Drake had been tethered to PlayStation hardware, but the PC release promised enhanced visuals, modding capabilities, and the fidelity that comes with high-end hardware. However, the launch was marred by a significant technical oversight: the game’s reliance on AVX2 instruction sets. For a segment of the PC user base, particularly those utilizing older but still capable CPUs, this requirement rendered the game unplayable. The subsequent development of an "AVX2 fix" by the modding community serves as a compelling case study in the friction between modern software optimization and hardware backward compatibility, highlighting the vital role of community intervention in the PC gaming ecosystem.
To understand the weight of this fix, one must first understand the technical hurdle. AVX2 (Advanced Vector Extensions 2) is an instruction set that debuted with Intel’s Haswell processors in 2013. It allows the CPU to handle heavy floating-point calculations more efficiently, which is crucial for physics simulations and complex AI behaviors—both staples of Uncharted 4’s gameplay. By compiling the game with AVX2 instructions hardcoded, the developers at Naughty Dog and Iron Galaxy effectively raised the floor for system requirements. While this decision streamlined performance for modern systems, it alienated users with CPUs that predated 2013, or certain low-budget processors that lacked AVX2 support. For these users, the game would crash immediately upon startup, not because their hardware lacked raw power, but because it lacked a specific vocabulary of instructions.
The emergence of a community-made AVX2 fix was a lifeline for these players. The fix functions by intercepting the game’s calls for AVX2 instructions and translating them into older, non-AVX equivalents (often SSE or AVX). This process is computationally expensive; it requires the CPU to do more work to achieve the same result, which can lead to performance bottlenecks. However, the very existence of the fix proved that Uncharted 4 was not fundamentally dependent on AVX2 for its logic to function. The instruction set was largely used for optimization shortcuts rather than essential operations. The fix revealed that the barrier to entry was artificial, or at least a matter of developer convenience rather than absolute necessity.
The saga of this fix underscores a recurring theme in modern PC gaming: the tension between optimization and accessibility. From a developer's perspective, targeting AVX2 allows for cleaner, more efficient code on the majority of target hardware. Supporting older instruction sets requires maintaining legacy code paths and testing on antiquated hardware—a resource drain for studios working on tight schedules. Yet, the PC platform is defined by its heterogeneity. Unlike consoles, where hardware is standardized, the PC market is a fragmented landscape of varying architectures and ages. By neglecting pre-AVX2 support, the developers ignored a core tenet of PC development: backward compatibility.
Furthermore, the rapid development of this fix highlights the unique resilience of the PC modding community. While official patches can take weeks or months to materialize—if they materialize at all—community members often reverse-engineer executables within days of a game's launch. This symbiotic, albeit unofficial, relationship between consumers and creators has preserved countless games. In the case of Uncharted 4, the community filled a gap left by the developers, ensuring that the game could reach the widest possible audience. It acts as a reminder that a game’s longevity is often secured not just by its creators, but by the passionate technologists who play them.
In conclusion, the AVX2 fix for Uncharted 4 represents more than just a patch to make a game run; it is a testament to the complexity of PC development and the value of open platforms. While the utilization of AVX2 was a logical step for optimizing a modern AAA title, the lack of a fallback option unnecessarily restricted the game’s reach. Through the technical prowess of the modding community, the barrier was dismantled, allowing the game to be experienced on hardware the developers had left behind. It stands as a lesson for future ports: in the pursuit of high-fidelity optimization, one must not forget the diverse heritage of the PC hardware landscape.
Here’s a helpful guide on the “Uncharted 4 AVX2 fix” — a common issue for players with older CPUs that don’t support AVX2 instructions.
