: This approach allowed users with modern hardware to continue benefiting from the performance optimizations of AVX2 while ensuring the game remained accessible to those on "legacy" hardware. Broader Impact
The saga of the "Uncharted 4 AVX2 fix" is a classic example of the challenges and community spirit of PC gaming. For most players, the solution is thankfully simple: ensure your game is updated to the latest version. The official patch released in November 2022 has effectively resolved the issue for owners of older but capable CPUs. However, if you're still facing problems or want to understand the technical details, the community methods provide a glimpse into the resourcefulness of PC gamers.

The is a community-made software patch that allows the game to run on older CPUs lacking Advanced Vector Extensions 2 (AVX2) support. When the Uncharted: Legacy of Thieves Collection launched on PC, Naughty Dog made AVX2 instructions a strict hardware requirement. Consequently, players using older but otherwise capable processors—such as Intel Ivy Bridge, Sandy Bridge, or first-generation AMD Ryzen chips—experienced immediate crashes to desktop on startup. To bypass this hardware limitation, modders developed an unofficial fix that translates or emulates these instructions, allowing the game to boot successfully.

: This method only works after you have removed Steam's DRM protection from the executable using a tool like Steamless . Attempting to modify the DRM-protected file directly may cause it to fail to launch.
B. Verify game updates
This method incurs a performance penalty of roughly 30–40%. You will not get 60 FPS on a legacy CPU. 30–40 FPS is the target. : This approach allowed users with modern hardware
This post will explain what AVX2 is, why Naughty Dog’s PC port demands it, and—most importantly—how to bypass it.
If you fall into the second category, keep reading.
Outdated drivers are a frequent cause of crashes and glitches. Download the latest drivers directly from NVIDIA or AMD. The official patch released in November 2022 has
Note: Because this emulates hardware instructions through software, it introduces massive CPU overhead and will significantly lower your framerate.
AVX2 allows CPUs to process larger blocks of data simultaneously. Modern game engines use these instructions to optimize heavy calculations. When Uncharted 4 attempts to run an AVX2 command on an unsupported CPU, the processor does not understand the instruction. This causes an unhandled exception, resulting in an instant crash to the desktop without an error message. Share public link
If you are running the most recent, fully updated version of Uncharted 4 on Steam or the Epic Games Store, you should first verify your files and attempt to launch the game without third-party mods, as official optimization patches may have already resolved your specific startup crash.
AVX2 is a hardware feature found in modern CPUs that allows the processor to execute commands faster by handling larger chunks of data simultaneously. Uncharted 4 uses these instructions for heavy engine calculations like physics, animations, and decompression.
