Uncharted 4 Avx2 Fix New -
If you are unable to use the official patch (e.g., if you are on an even older CPU that also lacks standard instructions), the community has documented these unofficial methods:
The definitive fix for the AVX2 limitation arrived via . Instead of removing AVX2 code paths entirely (which would degrade the performance of modern chips), the developers built a smart fallback execution system.
The is different. It leverages a combination of:
The developers addressed this limitation seamlessly via the game's update. Instead of completely removing AVX2 code—which would lower performance on modern machines—the team implemented an automated fallback executable system .
Q: What is the AVX2 fix for Uncharted 4? A: The AVX2 fix is a modification that resolves compatibility issues between Uncharted 4 and newer CPUs that support AVX2 instructions. uncharted 4 avx2 fix new
Example: "C:\IntelSDE\sde.exe" -hsw -- "D:\Games\Uncharted 4\u4.exe"
The primary method to fix the AVX2 error is using a specialized DLL wrapper or a modified executable. The most popular recent solution involves the "Intel SDE" (Software Development Emulator) or, more efficiently, a community-made "AVX2 bypass" patch found on repositories like GitHub or Nexus Mods. These tools intercept the AVX2 instructions and translate them into a format your older CPU can understand.
Update the game via Steam or Epic Games Store . If the game doesn't update automatically, you can verify game files on Steam to trigger the download. Alternative Workarounds
Then cross-reference your processor model with AVX2 support lists online. If you are unable to use the official patch (e
| Method | Difficulty | Effectiveness | Best For | | :--- | :--- | :--- | :--- | | | Very Easy | High (50-90+ FPS) | All users, especially those with a legit copy of the game. | | Community Hex Edit | Moderate | High (50-90+ FPS) | Users where the official patch doesn't work, or for specific game builds. | | Intel SDE Emulation | Hard | Low (~20 FPS, Buggy) | Users for whom no other solution works, and who are okay with a proof-of-concept. | | Hardware Upgrade | N/A | High (Best Performance) | Users who want a permanent solution for future games. |
The most reliable "fix" is now built directly into the game. On , developer Iron Galaxy released a major update (Patch 1.3.20812) that officially removed the AVX2 restriction.

To Nate, this wasn't just a technical glitch. It felt like a locked door in one of Henry Avery's ruins. His computer was a relic, a veteran of a hundred digital wars, powered by an old i7 processor that had seen better days. It didn't speak the modern "language" of AVX2, a specialized shorthand for math that newer chips used to run faster. Because his CPU couldn't understand those specific commands, the game simply refused to exist. It leverages a combination of: The developers addressed
This workaround is mainly interesting as a technical curiosity rather than a practical gaming solution. For a playable experience, upgrade your hardware or use the official patch.
: If an older CPU without AVX2 is found, the game automatically routes the launch path to alternative executables named u4-l.exe (for A Thief's End ) or tll-l.exe (for The Lost Legacy ).
Use the official Patch 3 instead, as it was specifically designed to provide a stable non-AVX2 code path.
