Uncharted 4 Avx2 Fix Hot! (Verified - PICK)

Use a library like MinHook to intercept system calls.

If the DLL fix doesn't work, ensure your system is optimized:

Copy the original u4.exe and any existing .dll files to a safe backup folder before altering anything.

Expect a 10–20% performance drop on very old CPUs. The game will be playable but may stutter during heavy physics scenes.

Sometimes, modern CPUs that do support AVX2 still crash due to how Windows handles instruction execution and memory management. Adjusting your security settings can resolve false-positive crashes. Click the Windows Start menu and type . Switch to the Program settings tab.

This official update is significantly more stable than early workarounds, which often caused severe lag or crashes. How to Apply the Fix Update Your Game: Ensure your game is updated to at least version or higher via Epic Games Store Verify Files: Use a library like MinHook to intercept system calls

Before the official patch, players used the Intel SDE to emulate AVX2 instructions. While this allowed the game to open, it often resulted in extremely poor performance (single-digit FPS) because software emulation is much slower than hardware-level execution.

Initially, the game required AVX2-capable CPUs (typically Intel Haswell 4th Gen or newer, and AMD Ryzen) to launch, causing immediate crashes on startup for users with older but otherwise capable hardware like Intel Sandy Bridge or Ivy Bridge i7s.

To resolve the in Uncharted: Legacy of Thieves Collection (which includes Uncharted 4 ), the most reliable solution is to update the game to Patch 3 (v1.3) or later . This official update was specifically released to introduce AVX2 support and allow the game to run on older CPUs that lack this instruction set. Official Fix: Patch 1.3 Update The game will be playable but may stutter

While unlikely, some users in early 2022 reported success by reverting to older, more stable driver versions (e.g., from 522.22 down to 517.48). What to Do If You're Still Having Issues

Players on Steam Community and Reddit expressed frustration, as these CPUs often exceeded the raw power of the original PlayStation 4 hardware but were barred by this "technicality". The Workarounds: Community Innovation

Outdated drivers are a frequent cause of crashes and glitches. Download the latest drivers directly from NVIDIA or AMD.

Upon its PC release, many players with older high-end CPUs (such as the legendary i7-3770K) found they could not even reach the main menu. The game would simply crash to desktop or throw an error because the executable relied on AVX2 instructions that these older architectures physically do not have. The Solution: How the Fix Works The fix is typically distributed as a modified or a replacement executable (often found on Nexus Mods ). It works by: Instruction Translation:
