4 Avx2 Fix Repack: Uncharted
If you are comfortable sharing, what and GPU are you currently using? Knowing your specs can help determine if any lingering performance issues are hardware-related or software-bound.
However, if you have a (a 10-core server CPU that lacks AVX2 but has massive bandwidth) paired with a modern GPU, this fix is a lifesaver. You can run the game at 4K/30 FPS smoothly.
: Uncharted 4 was built for the PlayStation 4, which uses a Jaguar CPU that does not support AVX2. uncharted 4 avx2 fix
On process start, the fix checks cpuid directly (bypassing potential anti-hook). If AVX2 is absent, it overwrites the game’s code section with fallback sequences. If AVX2 is present, it leaves the original instructions but still hooks CPUID to avoid potential detection.
(though FX supports basic AVX, it lacks full AVX2 support required by the game) The Official Solution: Game Patches If you are comfortable sharing, what and GPU
:
The PC gaming community quickly developed an unofficial solution to bypass the restriction. Independent modders created an (often distributed via Nexus Mods), which acts as an emulator or interceptor. It translates the game's AVX2 instructions into standard AVX or SSE instructions that older processors can understand. Step-by-Step Installation Guide You can run the game at 4K/30 FPS smoothly
: Lowering the NPC and crowd settings reduces the physics calculations the CPU has to manage.
On Ryzen 5 5600X, applying the fix (which still hooks CPUID) reduced performance by 8–12% due to forced fallback code paths. This confirms the fix is not recommended for AVX2-capable systems.
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.
