Sometimes the AVX2 crash is misidentified or caused by conflict with outdated drivers during the loading phase 1.2.3 .
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.
Better: On a 4.1 GHz i7-3770 with fix, frame rate in complex scenes is 28–34 fps. Without AVX2, the game does not run. However, we compared to a Haswell i7-4770K (AVX2) at similar clock: the i7-3770 with fix runs 42% slower on average. uncharted 4 avx2 fix
: Some community members shared hex values to manually patch the executable, though this was primarily used for disabling visual effects like TAA and DoF rather than bypassing core CPU instructions. Current Status
: Occasional frame drops during heavy combat or cinematic transitions. Longer Load Times : Shaders may take much longer to compile. Sometimes the AVX2 crash is misidentified or caused
“they recently released an update that made the game run on my shitty cpu :), i suggest you update the repack and it might work for you too.”
The official change log notes:
While official patches resolved this for many players, community-made AVX2 bypass fixes remain essential for gamers using older hardware or specific emulation layers. Here is the complete guide to understanding, installing, and troubleshooting the Uncharted 4 AVX2 fix. Why Uncharted 4 Crashes Without AVX2
Before you spend three hours tinkering with Intel SDE, ask yourself what CPU you actually have. Better: On a 4
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.
All test platforms without AVX2 successfully launched and completed the first three chapters. Previously, the game crashed at startup with EXCEPTION_ILLEGAL_INSTRUCTION at address 0x1412f4c30 . With the fix, no illegal instruction crashes occurred over 40+ hours of cumulative testing.
