On , Iron Galaxy Studios released the third major patch for Uncharted: Legacy of Thieves Collection on PC, bringing the game to version 1.3.20812 . In the patch notes, a crucial line read: "Added support for older CPUs without AVX2 feature support" . This is the most elegant solution because it requires no third-party tools or complex configuration.
For players using older hardware, the initial launch of on PC was frustrating due to a strict requirement for AVX2 instruction sets . This blocked owners of popular older CPUs—like the Intel Sandy Bridge (i7-2600K) or Ivy Bridge series—from even launching the game.
To verify the patch is installed, you can check in-game or in your game files that the version number is .
Open your client on Steam or the Epic Games Store. Allow the platform to download and install the latest game update. Ensure your version is v1.3 or higher.
How to Fix Uncharted 4 AVX2 Crashing Errors on Older CPUs The PC release of Uncharted: Legacy of Thieves Collection —which includes Uncharted 4: A Thief's End and Uncharted: The Lost Legacy —brought Nathan Drake's final adventures to a brand-new audience. However, many players running older or budget processors were immediately blocked from playing. The game initially shipped with a strict requirement for instruction sets. If your CPU lacked this feature, the game would crash straight to the desktop on launch. uncharted 4 avx2 fix new
If you can tell me the and your total RAM , I can tell you if the SDE method is likely to work or if you're better off trying a different solution.
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.
enterprise chips repurposed for budget gaming builds Community backlash was immediate, as processors like the Go to product viewer dialog for this item.
Here's how it works. After updating your game to this patch, the launcher will automatically detect your CPU. If it finds that your processor doesn't support AVX2, it intelligently switches to a fallback executable for the main game ( u4-l.exe ) or the Lost Legacy expansion ( tll-l.exe ). This is by far the simplest and most effective solution, allowing you to potentially play the game at 50-90+ FPS, depending on the rest of your hardware. On , Iron Galaxy Studios released the third
: This method is an emulation layer and typically results in extremely poor performance, often described as a "20 FPS slideshow". Minimum System Requirements Refresher
Example: "C:\IntelSDE\sde.exe" -hsw -- "D:\Games\Uncharted 4\u4.exe"
Sometimes, the AVX2 error is actually a masked driver issue. Ensure your NVIDIA, AMD, or Intel GPU drivers are updated to the latest version. 2. Verify Game Files
The Uncharted 4 AVX2 fix new (v3.2) transforms the game from a crashing, unplayable mess into a genuinely enjoyable single-player experience on CPUs like the legendary i7-2600K or i5-3570K. You will not hit 144 FPS. You will not use Ultra textures. But you will experience Nathan Drake’s final chapter—the explosive escape from the prison, the emotional closure with Elena, and the pirate treasure of Libertalia—all on hardware that is over a decade old. For players using older hardware, the initial launch
or later, which officially added support for older processors.
The was officially resolved by Naughty Dog and Iron Galaxy in Patch 3 (v1.3) , released in November 2022. This update added support for older CPUs (like the Intel Core i7-3770 or early AMD chips) that lack the AVX2 instruction set, which previously caused the game to crash on startup.
The "AVX2 fix" sparked intense community debate for several reasons: Efficiency vs. Accessibility
These methods are more complex and have significant performance drawbacks.
