Uncharted 4 Avx2 Fix ^hot^ «OFFICIAL · 2027»

For the best experience, ensure your GPU drivers are updated to the latest version (Nvidia 526.98 or higher recommended) to avoid persistent timeouts. is now officially supported?

When the game engine attempts to execute an AVX2 instruction on a CPU that doesn't understand it, the operating system throws an illegal instruction error, resulting in an instant crash to desktop (CTD) on launch.

The game should now open without the "AVX2 Not Supported" error, even if your CPU is older. Why Was AVX2 Needed in the First Place?

Intel itself provides a tool called (Software Development Emulator). It was designed for developers to test new instruction sets on old hardware. We can hijack this tool to run Uncharted 4 .

Regardless of the technical nuances, the official patch ultimately resolved the issue for most players. It is worth noting that Intel's SDE emulator was originally , not as a long-term solution for end-users. The fact that it was used extensively by gamers highlights the frustration caused by the artificial hardware lockout. uncharted 4 avx2 fix

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

C. Try community shim/patch (common approach)

You will likely experience this issue if you are running the game on: For the best experience, ensure your GPU drivers

Expect severe performance issues (e.g., 5-10 FPS) because instruction set emulation is extremely resource-intensive. 4. Other Potential Fixes (If it's not strictly a CPU issue)

Replace these instructions with a CALL to a custom function.

While the game will now launch on older CPUs (like the i7-2600K or i7-3770), keep the following in mind: Performance Goals: Minimum requirements target 720p at 30 FPS on Medium settings. Shader Compilation:

The problem arises because Uncharted 4: Legacy of Thieves Collection on PC was compiled to rely heavily on AVX2 instructions. Unlike some other games that include "fallback" code for older processors, Uncharted 4 attempts to execute these instructions immediately upon startup. If your CPU was released before 2013 (specifically Intel 4th Gen Haswell or older), your hardware cannot understand these instructions, leading to an instant crash. The game should now open without the "AVX2

If you want, I can:

Uncharted: Legacy of Thieves Collection brought the stunning adventures of Nathan Drake and Chloe Frazer to PC, but its launch was marred by technical hurdles for users with older hardware. A significant issue was the strict requirement for , causing the game to crash immediately or refuse to launch on CPUs that lacked this instruction set.

This means you don't need to do anything manually. The game just works—provided you have the latest patch installed. Newer CPU users continue to get the full AVX2 benefit, while older CPU owners can finally play without performance compromises.

While the community fix successfully bypasses the crash, it comes with a hardware cost. Emulating CPU instructions via software instead of executing them natively on hardware introduces significant performance overhead. Expected Performance Drops

: The fix is designed so that users with modern, AVX2-capable CPUs still benefit from the optimized AVX2 instruction path without any performance degradation. Community Feedback
