Beyond the AVX2 fix, the November 2022 patch brought numerous improvements:
The update seamlessly bypasses the hardware lock through a built-in automated system:
If you are running an older CPU—specifically Intel Core processors before the 4th Gen (Haswell) or older AMD CPUs—and are seeing crashes upon launch, you have encountered an incompatibility with the game's requirement for AVX2 instructions.
According to the official Naughty Dog Patch Notes , Iron Galaxy implemented a dual-executable fallback method: uncharted 4 avx2 fix new
If a hardware upgrade isn't feasible, consider playing Uncharted 4 on a different platform. Uncharted: The Nathan Drake Collection and Uncharted 4: A Thief’s End are available on PlayStation consoles.
The developers addressed this limitation seamlessly via the game's update. Instead of completely removing AVX2 code—which would lower performance on modern machines—the team implemented an automated fallback executable system .
Uncharted 4 , being a port of a PlayStation 4 game, was compiled with AVX2 support enabled by default. The PS4’s CPU (Jaguar) does not actually support AVX2, but the PC port’s compiler (likely Clang or MSVC) assumed a modern x86-64 CPU. Beyond the AVX2 fix, the November 2022 patch
For the last two years, the only solutions were draconian:
If your game files are updated but your custom launcher shortcuts are broken, navigate to your root installation folder (e.g., Steamapps\common\Uncharted Legacy of Thieves Collection\ ). Look for . Creating a direct desktop shortcut from this specific "legacy" executable bypasses the launcher's automated CPU check and runs the game in non-AVX2 mode natively.
Some users have successfully used the Intel SDE to emulate missing instructions, though this typically results in extremely poor performance. The developers addressed this limitation seamlessly via the

is an extension to the x86 instruction set architecture for microprocessors from Intel and AMD. Introduced in 2013 with Intel’s Haswell architecture and AMD’s Excavator line, AVX2 expands vector processing capabilities, allowing the CPU to execute data-heavy mathematical equations much faster.
