AVX2 (Advanced Vector Extensions 2) is an instruction set included in CPUs produced by Intel starting with its and by AMD with its Excavator architecture (2015) . In simple terms, these are specialized commands built into your processor that allow it to handle complex mathematical operations much faster—operations often required by modern, resource-intensive games.

This method does not emulate; it simply deletes the CPU check. The game may behave unpredictably (random physics glitches, audio popping) if it tries to use an AVX2 instruction that doesn’t exist. However, it offers native performance. uncharted 4 avx2 fix

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.

On your first launch with an AVX2 fix, the game must compile building blocks called shaders. This process naturally maxes out CPU utilization. On legacy processors utilizing an AVX2 bypass mod, this process can take anywhere from . Do not close the game if it appears stuck on the initial loading screen; allow the progress bar to complete.

For users who want to manually disable the AVX2 flag in the game files, a HEX edit method exists. This involves directly modifying the executable to remove the check.

Expect a 10–20% performance drop on very old CPUs. The game will be playable but may stutter during heavy physics scenes.

Intel 4th gen (Haswell) and newer, AMD Ryzen and some late FX. Not supported: Intel Core 2 Duo, 1st–3rd gen Core (i7-9xx, i7-2xxx, i7-3xxx), AMD Phenom, Bulldozer (unless Excavator variant).

Iron Galaxy and Naughty Dog optimized Uncharted 4 on PC to heavily rely on AVX2 instructions.

It converts those commands into standard AVX or SSE4.2 instructions that older CPUs understand.

Initial asset streaming and level loading will take significantly longer. Official Developer Updates This method does not emulate; it simply deletes
