If you are trying to launch Uncharted: Legacy of Thieves Collection on PC and getting an immediate crash to desktop, your processor is likely missing Advanced Vector Extensions 2 (AVX2). Naughty Dog's PC port originally required this specific CPU instruction set to run.
PC gaming’s greatest strength is its backwards compatibility. While Naughty Dog failed to accommodate legacy hardware, the community’s Uncharted 4 AVX2 fix ensures that no one has to upgrade their CPU just to play a six-year-old console port.
Before anything else, ensure your PC meets at least the minimum specs for the game, aside from the CPU:
: This tool can emulate the AVX2 instruction set on unsupported CPUs. Pros : Allows the game to launch. uncharted 4 avx2 fix
You may notice slightly higher CPU usage or occasional stuttering compared to a native AVX2 system, as the CPU has to work harder to process the "translated" instructions. Crash Frequency:
Enter the modding community and the "fix."
Intercepting the AVX2 calls and redirecting them to standard AVX or SSE instructions. Bypassing Checks: If you are trying to launch Uncharted: Legacy
Intel’s (Software Development Emulator) can emulate AVX2 on older CPUs.
Cap your framerate to using your GPU control panel (NVIDIA Control Panel or AMD Software) to normalize CPU frame pacing.
The modded executable is superior for performance. However, the Intel SDE is more stable and won't corrupt your save file. While Naughty Dog failed to accommodate legacy hardware,
Intel Core i7/i5/i3 processors from the Ivy Bridge (3rd Gen) era or older. Intel Pentium and Celeron budget chips. AMD Phenom, FX-Series, or early APUs. Step 1: Check Your Official Game Version
Drag and drop the extracted files (usually including a modified DLL or an injector executable) directly into the main game folder where u4.exe resides.
These official updates mitigated many AVX2-related errors by providing alternative instruction code paths for older processors, significantly improving stability without third-party mods. Method 3: Adjusting Windows Exploit Protection
