If you are struggling to run the game, check if your system meets the minimum requirements, especially regarding RAM and GPU, as the AVX2 fix only resolves the CPU instruction issue.
: Navigate to the display menu and activate AMD FSR 2 or Intel XeSS to scale up performance.
When Uncharted 4: A Thief’s End and The Lost Legacy were bundled into the Legacy of Thieves Collection and released on PC in late 2022, fans of Nathan Drake rejoiced. Finally, the cinematic masterpiece that pushed the PS4 to its limits was available on desktops and laptops with unlocked frame rates and ultra-wide support.
If you are on a CPU older than an Intel 4th Generation (Haswell) or AMD Ryzen, it is highly recommended to consider upgrading your hardware for the best experience. Uncharted 4 is a demanding title, and the AVX2 fix is a band-aid that may not provide a stable 60 FPS experience. uncharted+4+avx2+fix+free
Following community outcry, iron Galaxy and Sony eventually released an official patch (v1.3) that added support for older CPUs. This is the most stable and reliable "fix" available.
) originally required CPUs with AVX2 support to launch, the developers officially removed this restriction in Patch 3 (v1.3.20812)
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. If you are struggling to run the game,
When searching online for terms like "Uncharted 4 AVX2 fix free download," you will often encounter YouTube videos and sketchy file-hosting domains offering .exe replacements or specific .dll files.
AVX2 (Advanced Vector Extensions 2) is an instruction set introduced by Intel with its . It was designed to accelerate computationally intensive tasks — complex mathematical calculations, physics simulations, character animations, and facial expressions — by allowing the CPU to process larger chunks of data in a single cycle.
While it may run, it often results in a "20 FPS slideshow" in intense scenes, though menus might run fine. Finally, the cinematic masterpiece that pushed the PS4
The community has developed a "wrapper" or "fix" that intercepts these instructions and translates them into a language your older CPU can understand. Where to Find the Fix
If a website asks for your credit card to download an "AVX2 patch" for Uncharted 4 , close the tab. The tools described here (Intel SDE + a Notepad script) are 100% free and open-source.
To make it playable, you must set all graphical settings to the lowest (Low or Normal), reduce resolution to 720p or lower, and ensure shaders have finished compiling.
Because you are translating instructions, performance will not be native. Here is how to maximize your frames on an older CPU:
