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.
Use a library like MinHook to intercept system calls.

How to Fix Uncharted 4 AVX2 Crashing and CPU Limitations The PC release of Uncharted: Legacy of Thieves Collection —which includes Uncharted 4: A Thief's End —brought Nathan Drake's final adventure to a broader audience. However, many players with older or budget processors were met with immediate crashes to desktop or a refusal to launch. The culprit behind these issues is the game's strict requirement for the instruction set.
A simplified conceptual snippet for handling an AVX2 instruction in a CPU that only supports AVX:
Today, the solution is simple: The AVX2 requirement is no longer a barrier to entry. The game intelligently adapts to your hardware, letting modern systems run at peak performance with AVX2 enabled while providing a stable, playable experience for those with older, AVX2-lacking processors. The drama served as a reminder that for developers, a simple compiler flag can have unforeseen consequences, and for players, sometimes the best "fix" is a little patience.
The "Uncharted 4 AVX2 fix" issue is a classic PC gaming parable, demonstrating the delicate balance between pushing for higher performance with modern CPU instructions and ensuring broad compatibility for the diverse range of hardware in the PC ecosystem. While the initial requirement was a frustrating and arbitrary barrier for many, it was quickly resolved by an official patch.
