: This method allows users with newer CPUs to still benefit from AVX2 support without any impact to their performance, as the game automatically detects which executable to use based on your hardware.

Scan the game memory for AVX2 opcodes (e.g., VZEROUPPER , VEXTRACTF128 ).

When attempting to launch the game, users on older hardware often encounter an immediate crash to desktop (CTD) or a "Something went wrong" crash report. This is because the game engine specifically requires the CPU to support AVX2 instructions for high-performance processing, which older processors lack.

Uncharted 4 offloads a large portion of its spatial audio processing to vector instructions. Bypassing them can sometimes cause audio desynchronization or crackling during heavy action sequences.

Solved: How to Fix the Uncharted 4 AVX2 CPU Requirement on PC

If you are running the most recent, fully updated version of Uncharted 4 on Steam or the Epic Games Store, you should first verify your files and attempt to launch the game without third-party mods, as official optimization patches may have already resolved your specific startup crash.

Not sure if your processor is affected by this issue? Here are three easy ways to check:

The physics for the grappling hook specifically uses the VPMULHUW AVX2 instruction (which is hard to emulate). Fix: In the Intel SDE, use the -mix flag to log which instruction crashed, but generally, switching to Method 2 fixes this.

: Use AMD FSR or Intel XeSS in "Performance" mode to alleviate total system strain. Troubleshooting Common Errors Game Closes Immediately After Loading Screens

Since the game doesn’t have an official patch to disable AVX2, the community uses a binary modification or a dynamic emulation layer. The most reliable method is using a wrapper tool (similar to those for older games) that translates AVX2 instructions into AVX or SSE4.
