How to Fix Uncharted 4 "Unsupported CPU" Error: The Free AVX2 Solution
If you’re trying to launch Uncharted: Legacy of Thieves Collection on an older PC and getting a crash or an "unsupported CPU" error, the culprit is likely the AVX2 instruction set requirement. While many modern games require this feature, owners of classic CPUs like the Intel Core i7-2600K or i5-3570K were initially left in the dark.
The good news is that you no longer need third-party "fix" files or risky community patches to play. The developer officially patched out this restriction. The Official Fix: Update Your Game
On November 16, 2022, Iron Galaxy released a major update (Version 1.3) that added support for non-AVX2 CPUs. This is the safest and most effective way to play Uncharted 4 for free if you already own the game.
Automatic Fallback: When the game detects an older CPU, it now automatically switches to a fallback executable (u4-l.exe for Uncharted 4 or tll-l.exe for The Lost Legacy).
Performance: This method allows users with newer CPUs to keep their performance benefits while letting legacy hardware run the game without crashing.
How to get it: Simply update the game through the Steam or Epic Games Store client. Alternative Method: Intel SDE Emulator (Not Recommended)
Before the official patch, players used the Intel Software Development Emulator (SDE) to trick the game into thinking the CPU supported AVX2.
The Process: You would run the game through an SDE command-line shortcut.
The Catch: This method often results in a "20 FPS slideshow" and frequent crashes. It is generally considered unplayable compared to the official developer patch. Additional Troubleshooting for Older CPUs
Even with the AVX2 fix, older processors may struggle with stability. If the game still crashes, try these community-verified steps: UNCHARTED - AVX2 fixed on old CPUs - Steam Community

The Uncharted Quest: AVX2 Fix
Nathan Drake, the renowned treasure hunter, sat in his dimly lit office, staring at a cryptic map spread out before him. His trusty sidekick, Victor Sullivan, entered the room, a hint of excitement in his voice.
"Nat, I've got something," Sully said, holding up a dusty old journal. "This belonged to a infamous explorer, known only as 'The Architect.' Rumor has it, he discovered a powerful artifact hidden deep within the Amazon rainforest."
Drake's eyes lit up. "The fabled AVX2 treasure?" He had heard whispers of this mythical loot, said to grant unimaginable power to its possessor.
Sully nodded. "The Architect's journal hints at a location, but there's a catch. The coordinates are encrypted, and the only way to decipher them is by solving a series of complex puzzles."
Without hesitation, Drake and Sully embarked on their perilous quest. They traversed treacherous jungles, avoiding deadly traps and rival treasure hunters. As they journeyed deeper into the heart of the rainforest, they stumbled upon an ancient temple.
Inside, they found a mysterious computer terminal with a cryptic message: "AVX2-fix required." A holographic display flickered to life, revealing a complex algorithm that needed to be solved.
Drake, being the expert in cryptography, quickly got to work. He noticed that the algorithm required a specific instruction set – AVX2. The problem was, their current hardware didn't support it.
Sully, ever the resourceful partner, pulled out an old laptop from his backpack. "I prepared for this contingency, Nat. This laptop has an AVX2-enabled processor. Let's get to work."
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.
As they opened the chest, a burst of energy illuminated the room. Inside, they found an ancient artifact, pulsing with an otherworldly power.
But, to their surprise, they weren't alone. A rival treasure hunter, known only as "The Shadow," emerged from the shadows, intent on claiming the treasure for himself.
A tense standoff ensued, with Drake and Sully refusing to back down. In the end, they managed to outwit The Shadow and escape the temple, artifact in hand.
As they made their way back to civilization, Drake couldn't help but feel a sense of pride and accomplishment. The AVX2 fix had been the key to unlocking the treasure, and their partnership had proven unbreakable.
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 END
How was that? Did I meet your expectations?

🎮 Guide: Fixing the "AVX2" Error in Uncharted 4 on PC (Steam/Epic)
Are you trying to run Uncharted: Legacy of Thieves Collection on your PC and encountering an immediate crash or an error related to "AVX2"? You aren't alone.
With the recent surge in players grabbing the game (perhaps during a free giveaway or a deep discount), many users are discovering that their hardware isn't quite up to the task—not because of graphics power, but because of specific processor instructions. How to Fix Uncharted 4 "Unsupported CPU" Error:
Here is a breakdown of what the AVX2 issue is, why it happens, and how the community "fix" works.
Performance Tweaks for the AVX2 Fix
Because you are translating instructions, performance will not be native. Here is how to maximize your frames on an older CPU:
- Lower the Physics Quality: Set "Physics" to Medium or Low. This reduces the number of AVX2 calls the game makes.
- Texture Streaming: Set to Medium. Older CPUs typically pair with older GPUs (GTX 960/1060 or RX 580). High textures will cause stuttering.
- Resolution: Stick to 1080p. This fix struggles with 1440p and 4K on Sandy/Ivy Bridge chips.
- CPU Affinity: Open Task Manager while the game runs, right-click
Uncharted4.exe, go to "Details," and set "Priority" to High. Do not change affinity (leave all cores checked).
