If you have an older CPU that's still perfectly capable of running modern games, you don't have to miss out on this acclaimed adventure. While it was a major hurdle at launch, several reliable and effective fixes have been developed to help you bypass this requirement. This guide will walk you through every method, from simple, official patches to advanced community workarounds.
This allows older CPUs (like Intel Sandy Bridge or Ivy Bridge) to launch the game without third-party mods. Legacy/Unofficial "Fixes"
If you are currently experiencing startup issues, follow these steps to ensure you are utilizing the official solution. Step 1: Force an Update on Steam or Epic Games Store
Nate sat in his home office, the low hum of his aging PC the only sound in the room. He was staring at a digital artifact—the Uncharted: Legacy of Thieves Collection —but every time he tried to launch it, the screen went black. The error was always the same: "Missing AVX2 Support." uncharted 4 avx2 fix new
Extract the archive contents directly to an easily accessible folder. Create a desktop shortcut for sde.exe .
Advanced Vector Extensions 2 (AVX2) is an instruction set extension for x86 CPUs. It allows processors to execute vector instructions faster, boosting performance in data-heavy tasks like physics rendering and audio processing.
Furthermore, the rapid development of this fix highlights the unique resilience of the PC modding community. While official patches can take weeks or months to materialize—if they materialize at all—community members often reverse-engineer executables within days of a game's launch. This symbiotic, albeit unofficial, relationship between consumers and creators has preserved countless games. In the case of Uncharted 4 , the community filled a gap left by the developers, ensuring that the game could reach the widest possible audience. It acts as a reminder that a game’s longevity is often secured not just by its creators, but by the passionate technologists who play them. If you have an older CPU that's still
According to the official Naughty Dog Patch Notes , Iron Galaxy implemented a dual-executable fallback method:
A: The easiest way is to download a free tool called CPU-Z . Install and run it; on the main "CPU" tab, check the "Instructions" line. If you see "AVX2" listed, you're good to go. If you don't, you'll need one of the fixes above.
You’ve just downloaded Uncharted 4: Legacy of Thieves Collection on PC. You meet the requirements — almost. Your older CPU (e.g., Intel 3rd/4th Gen or an early AMD FX) lacks AVX2 instructions. The game crashes on launch with a silent exit or an error about “unsupported instruction.” This allows older CPUs (like Intel Sandy Bridge

If the game still fails to launch, right-click the game in your library, go to Properties > Installed Files , and select Verify integrity of game files to ensure you have the latest executables. Check Version:
Navigate to your and select UNCHARTED: Legacy of Thieves Collection . Right-click the game title and select Properties .
Before diving into the solutions, it's helpful to understand the core of the problem. AVX2 is a set of instructions used by modern CPUs to accelerate complex mathematical operations, particularly in fields like video encoding, scientific computing, and, of course, gaming. Game developers use it to optimize performance for specific tasks. The issue arises when a game is coded to require AVX2 support without a fallback option for older hardware. At launch, Uncharted: Legacy of Thieves Collection did exactly this, leading to a crash for many users with perfectly capable processors.
