There are a few well-known workarounds utilized by the PC gaming community to bypass AVX/AVX2 requirements. These fixes essentially intercept the game's calls for AVX2 instructions and translate them so your older processor can understand them.
Uncharted 4 AVX2 Fix Free: How to Play on Older CPUs Uncharted: Legacy of Thieves Collection brought Nathan Drake's final adventure to PC, but its initial launch left many players with older processors (CPUs) unable to start the game. A specific technical requirement— instructions—prevented processors older than Intel's 4th Generation Haswell or older AMD models from launching the title, resulting in an immediate crash or an "AVX2 not supported" error.
AVX2 was introduced with the Haswell (4th Gen) architecture. If your CPU is older (e.g., i7-2600K, i7-3770K), you lack AVX2.
If your CPU does not support AVX2 (common in Intel CPUs before the 4th Generation Haswell), the game's executable attempts to run, cannot interpret the instructions, and immediately crashes. The Official Solution: Patch 3 (Version 1.3)
Note: Because the SDE tool is translating instructions in real-time, you may notice a slight drop in overall frame rate (FPS), but it will allow the game to boot and run. Method 2: Replacing the Executable (Community Patches) uncharted+4+avx2+fix+free
If an older CPU is detected, the game automatically routes processing to a compatible, non-AVX2 executable file ( u4-l.exe for Uncharted 4 or tll-l.exe for The Lost Legacy). How to Install the Official Patch via Steam Open your .
: 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.
e.g., i7-920, i7-2600K, i7-3770K (Nehalem, Sandy Bridge, Ivy Bridge).
When Uncharted: Legacy of Thieves Collection (which includes Uncharted 4: A Thief's End and Uncharted: The Lost Legacy ) launched on PC, many players running older but still capable processors were met with an immediate crash-to-desktop (CTD) or a black screen upon startup. There are a few well-known workarounds utilized by
To run Uncharted 4 on older hardware, simply double-click . This exe file bypasses the AVX2 requirement entirely.
What are you seeing when the game crashes?
Error message mentions AVX2 , unsupported instruction , or a crash dump . Launcher starts, but game fails when clicking "Play".
Ensure you are using NVIDIA driver 526.98 or higher to resolve known stability issues. If your CPU does not support AVX2 (common
If updating the game and launching u4-l.exe doesn't work—or if you are using an unofficial copy of the game—you may need to use more advanced techniques to emulate the missing instructions.
like GitHub, Nexus Mods, or dedicated CS.RIN.RU threads.
The best solution depends entirely on your technical comfort level. With the official patch v1.3 from Naughty Dog and Iron Galaxy, many users on older hardware can simply run the u4-l.exe executable and be done. If you are still locked out, the Intel SDE emulator is the most technically robust (though slowest) workaround. If you are aiming for better performance, a dedicated "NoAVX" community patch might be the way to go, though you should verify the integrity of the files before installation.
