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.
For owners of high-end hardware from the pre-Haswell era (roughly pre-2013 Intel chips, like the beloved Ivy Bridge i7-3770K or early Xeons), the game would crash immediately upon startup. The executable was hard-coded to utilize AVX2 instructions for processing complex mathematical operations efficiently. If the processor didn't speak that specific dialect of code, the program simply had no fallback language. It was a binary gatekeeper: have AVX2, or play nothing. uncharted 4 avx2 fix
Enables play on older, popular hardware (Intel 3rd Gen, older AMD FX). Easy to install (usually a simple file drag-and-drop). Maintains surprisingly consistent frame rates. Not officially supported; game updates may break the fix. Minor performance overhead due to instruction emulation. for the current version of the fix? If your hardware is below these specs, the
When the game detects an older processor, it automatically switches to a fallback executable ( u4-l.exe for Uncharted 4 or tll-l.exe for The Lost Legacy ). The executable was hard-coded to utilize AVX2 instructions
