If you're using a very old CPU (e.g., Intel 2nd or 3rd gen), you may face another limitation: although the game can now launch, performance may still be below expectations even with the AVX2 fix. For those hardware configurations, reducing in‑game settings and waiting for full shader compilation can help improve frame rates. uncharted 4 avx2 fix new

As of early 2025, Sony has not released an official AVX2 fallback. Nixxes Software (the porting studio) has remained silent. Given that the Legacy of Thieves Collection is now over two years old on PC, a retrospective patch is highly unlikely.

To apply the newest fix, you typically need to download the patched files and place them directly into your Uncharted 4 installation folder, where the main .exe resides. Most users report that the "Alternative Launchers" created by the modding community offer better stability and higher frame rates than the official workaround. Always ensure you are using the latest version of these mods, as they are frequently updated to work with the most recent Steam and Epic Games Store versions of the game.

If you are running the game through major digital storefronts like Steam or Epic Games Store, the installation of this fix should be automatic. Use the following steps to verify your game is updated correctly: As of early 2025, Sony has not released

If the automated fallback routine fails, you can simulate AVX2 instructions using Intel's legacy testing utilities.

Leo found a refined script from a GitHub user “AVX2Patch” (updated Jan 2025). Instead of emulating all instructions, it used selective emulation + a Vulkan wrapper to reduce overhead.

is an instruction set introduced by Intel with the Haswell architecture (2013) and later by AMD with the Excavator architecture (2015). These instructions allow the CPU to perform mathematical operations on large vectors (multiple pieces of data) in a single clock cycle. Game engines love AVX2 for physics calculations, environmental decompression, and shader compilation.
