Uncharted 4 Avx2 Fix New Jun 2026
Fortunately, there are that allow you to bypass this requirement and get Uncharted 4 running, even on older hardware. What is the Uncharted 4 AVX2 Error?
Go to the tab and click Change under Virtual Memory. Uncheck "Automatically manage pagefile size".
Extract the archive contents directly to an easily accessible folder. Create a desktop shortcut for sde.exe .
This is the new fix. It does not modify the original EXE.
Before the official patch existed, some users successfully ran Uncharted 4 using Intel's —a tool designed to emulate new instruction sets on older hardware. uncharted 4 avx2 fix new
Run the application using the following command structure: sde.exe -- u4.exe
If you need the or a step-by-step guide for FEX-Emu on Windows (since it’s Linux-native), let me know, and I’ll adapt the story into a direct tutorial.
| 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. |

Before official fixes were perfected, community modders developed a workaround using an Intel software tool called or custom script wrappers. These tools mimic AVX2 instructions via software, tricking the game into thinking your CPU natively supports them. Step-by-Step Installation
: How to Play Legacy of Thieves on Older CPUs
Just as Nate was about to give up and consign his old rig to the scrap heap, a notification pinged. .
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. Uncheck "Automatically manage pagefile size"
If you can tell me the and your total RAM , I can tell you if the SDE method is likely to work or if you're better off trying a different solution.
Older AMD chips that lack full AVX2 functionality.
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.
Example Target: C:\SDE\sde.exe -hsw -- "C:\Games\Uncharted\u4.exe" .
Players with newer processors continue to utilize the standard AVX2 binary without experiencing any performance regressions.
