While the community fix successfully bypasses the crash, it comes with a hardware cost. Emulating CPU instructions via software instead of executing them natively on hardware introduces significant performance overhead. Expected Performance Drops

If your hardware is below these specs, the official stance from the developers is that your system does not meet the minimum requirements. However, the community has developed workarounds.
: Extremely poor performance (often 7–15 FPS) and frequent crashes. uncharted 4 avx2 fix
The first challenge for many players is simply understanding what AVX2 means. It's a technical barrier that can be confusing.
: Open Steam, right-click Uncharted: Legacy of Thieves Collection , select Manage , and click Browse local files .
The fix intercepts AVX2 commands before they reach the CPU. While the community fix successfully bypasses the crash,
The community fix relies on instruction emulation, typically utilizing Intel’s Software Development Emulator (SDE) or custom-compiled dynamic-link libraries (DLLs) like tbb.dll .
Because on paper, the Legacy of Thieves Collection lists an Intel i7-4770 (Haswell) as the minimum requirement. That chip supports AVX2. However, many gamers with perfectly capable CPUs—like the Intel i7-2600K (Sandy Bridge), i7-3770K (Ivy Bridge), or AMD Phenom II —found the game refused to launch. These chips are fast enough to run the game, but lack the specific instruction set.
The on PC (which includes Uncharted 4: A Thief's End ) originally required CPUs to support the AVX2 instruction set , causing crashes or startup failures for users with older processors like the Intel Sandy Bridge or Ivy Bridge series. Official Fix However, the community has developed workarounds
Initial asset streaming and level loading will take significantly longer. Official Developer Updates
, proceed to the workaround steps below. 2. Updated Graphics Drivers (NVIDIA/AMD)
The most important "fix" for the Uncharted 4 AVX2 issue is to .
: As the emulator translates code on the fly, you will likely encounter frame-time spikes and stuttering during chaotic action sequences or map transitions.
