New: Uncharted 4 Avx2 Fix

While the game is now playable on older CPUs, reviewers have noted that performance is generally better when the game is GPU-bound, though some users report a smooth experience even on decade-old processors. How to Apply the Fix Update via Steam/Epic:

Community testing shows that the performance penalty of running the non-AVX2 fallback path is surprisingly negligible. In side-by-side benchmarks using older hardware like the Core i7-3770, framerates remained stable and smooth, assuming the PC met the general graphical requirements.

You can verify your version in the game properties to confirm you are on the "Patch 3" build or higher.

I will cite the sources appropriately. situation around the "Uncharted 4 AVX2 fix" has been a journey for PC gamers with older CPUs. When the game first launched, it required a processor with the AVX2 instruction set, which immediately locked out many otherwise capable systems. Thankfully, thanks to community ingenuity and, most notably, an official developer patch, the landscape has since changed. Today, the complete and definitive answer to the problem lies in the game's own files, making an elaborate fix unnecessary for most players.

If the official patch doesn't resolve your issue (or if you're using an older game version), consider these community-developed workarounds.

The Uncharted 4 game engine utilizes AVX2 instructions to optimize performance on compatible processors. This allows for smoother gameplay, more detailed graphics, and a more immersive gaming experience. However, if your processor does not support AVX2, the game will not run, leading to frustration for those trying to play it on older hardware.

Ensure your game is fully updated to the latest version on Steam or the Epic Games Store.

When Uncharted 4: A Thief's End and The Lost Legacy made their way to PC via the remastered bundle, the engine was compiled to strictly require AVX2. If you attempted to open the game on iconic legacy chips—such as the Intel Core i7-2600K (Sandy Bridge) or i7-3770 (Ivy Bridge)—the game would instantly crash because the CPU literally did not understand the instruction code. While the game is now playable on older

: While the game is now playable on older hardware, these CPUs may still experience lower frame rates and occasional stuttering compared to modern processors, as AVX2 is used to accelerate specific game functions.

Some users have successfully used the Intel SDE to emulate missing instructions, though this typically results in extremely poor performance.

The fix works by:

The definitive solution for the issue is the official game patch released by developer Iron Galaxy, which completely removes the AVX2 CPU restriction and introduces automatic fallback executables ( u4-l.exe and tll-l.exe ) for older processors. When UNCHARTED: Legacy of Thieves Collection initially launched on PC, thousands of players with older, yet capable hardware were locked out. The game simply refused to launch, crashing straight to the desktop because it strictly required Advanced Vector Extensions 2 (AVX2) instruction sets.

: AVX2 instructions act as "accelerators" for math functions. While removing the requirement makes the game accessible, users on older hardware may still experience lower frame rates or stuttering. Legacy Hardware Viability

Instead of relying on unstable community scripts or emulation hacks, Iron Galaxy deployed an official in Patch 3 (Version 1.3).
