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.
Avoid downloading third-party "AVX2 fix" files from unknown forums, YouTube descriptions, or sites offering .exe hacks. Many of these are malware or trojans . The only safe, free fix is the official patch. Why Did Uncharted 4 Need AVX2?
Iron Galaxy and Naughty Dog quickly became aware of the backlash from the community. In a responsive move, they released the (also known as the November 16th Update) which officially removed the AVX2 requirement. uncharted+4+avx2+fix+free
However, for those using legacy versions who need a DIY approach, the method provides a working, legitimate alternative. But for the best experience, updating your game or, in the long run, your hardware is the path to the smoothest treasure hunting experience. Now go find that treasure!
Before the official patch, players used the to trick the game into thinking the CPU supported AVX2.
The artifact, now in their possession, would remain a secret, its power hidden from those who would misuse it. Drake and Sully shared a knowing glance – their next adventure was just around the corner. The simplest way to resolve the crash is
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 .
When UNCHARTED: Legacy of Thieves Collection first launched on PC, thousands of players with older processors were locked out. The game hard-required instructions, causing immediate crashes or "Unsupported CPU" errors on highly capable older chips like Intel Sandy Bridge/Ivy Bridge (e.g., i7-2600K, i7-3770K) and older AMD FX processors.
Here is a step-by-step guide to using the Intel SDE as a community fix: Launch the game normally
Before diving into the solution, it helps to understand why this is happening. AVX2 (Advanced Vector Extensions 2) is a set of instructions that modern CPUs use to speed up heavy computational tasks. Think of it as a language for your processor. When a game like Uncharted 4 is coded, it assumes your CPU "speaks" AVX2 fluently. If your processor doesn't understand that specific language, the game has no way to communicate with it and simply crashes.

With the laptop, they were able to crack the code, and the terminal beeped, revealing the coordinates. The duo followed the map, overcoming countless obstacles, until they finally reached the treasure.
Technically, developers can remove the AVX2 requirement by flipping a compiler switch. By removing the AVX2 flag, the compiler falls back to using , an instruction set that is supported by almost every CPU from the last 15 years. As one user pointed out in the Steam discussions: "There's no technical reason for the game to require AVX2... You just remove the flag, and SSE 4.2 is used in its place". The community patches essentially automate this switch for users.
