Uncharted 4 Avx2 Fix New <TRUSTED – ANTHOLOGY>

The "AVX2 fix" for Uncharted 4: Legacy of Thieves Collection

on PC primarily refers to Patch 1.3 (v1.3.20812), released by Iron Galaxy in November 2022. This update officially added support for older CPUs that lack the AVX2 instruction set, such as the Intel Sandy Bridge (i7-2600K) or early AMD FX series. Performance & Stability Review

Official Compatibility: The game now includes a "fallback" executable (u4-l.exe and tll-l.exe) that automatically launches if an older CPU is detected. This ensures users with newer CPUs still benefit from AVX2 optimizations without impact.

Older CPU Performance: Users with high-end older hardware, such as an overclocked i7-2700K, report reaching 60 FPS at 1080p on max settings with stable performance. However, very weak or entry-level older CPUs (like the Pentium G4600) may still struggle to launch or run the game smoothly.

Stability: While the official patch resolved the "illegal instruction" crashes for most, some users on extremely old hardware (without even basic AVX support) still report issues. uncharted 4 avx2 fix new

Additional Fixes: This specific update also improved mouse behavior, specifically addressing choppy camera movement when strafing and fixing loss of control in windowed mode. Technical Context

What is AVX2?: It is a CPU instruction set used to optimize complex math in games. Before the patch, the lack of these instructions caused the game to crash immediately on launch for many legacy systems.

Wait for Shaders: For best performance regardless of your CPU, you must let the game finish "Building Shaders" at the main menu (bottom right corner). Skipping this often leads to micro-stuttering and high CPU temperatures. Verdict for Legacy Users Our Third Patch Is Live! :: UNCHARTED - Steam Community

I notice you're asking about an "AVX2 fix" for Uncharted 4 on PC. The "AVX2 fix" for Uncharted 4: Legacy of

Here's the direct, honest answer:

There is no legitimate "AVX2 fix" that enables Uncharted 4 to run on CPUs lacking AVX2 instructions.

What people falsely claim as "AVX2 fixes":

• Modified EXE files – These are usually malware or game cracks that don't actually fix AVX2.
• Emulation layers – Not available for AVX2 in this game; emulating AVX2 would be far too slow.
• BIOS hacks – None exist.

Is There an Official Patch Coming from Sony?

As of early 2025, Sony has not released an official AVX2 fallback. Nixxes Software (the porting studio) has remained silent. Given that the Legacy of Thieves Collection is now over two years old on PC, a retrospective patch is highly unlikely.

The "new" fix is, for all intents and purposes, the final community solution. However, a word of caution: Do not attempt to play the multiplayer mode (Survival or Team Deathmatch) with the AVX2 proxy active. While the game will let you connect, the translation overhead causes desynchronization, leading to a temporary (24-hour) matchmaking ban. Modified EXE files – These are usually malware

2. Software Workarounds

There are no guaranteed software workarounds to bypass the AVX2 requirement. The game fundamentally requires AVX2 instructions to run.

Step 4: Launch Parameters (For Steam Users)

If the DLL method crashes, use the new command-line switch discovered in December 2024. Right-click Uncharted 4 in Steam → Properties → Launch Options. Enter: -noavx2 -force_sse4

For the Epic Games Store version, add these to the Additional Command Line Arguments in the launcher’s settings.

What is the AVX2 issue in Uncharted 4?

• Uncharted 4: A Thief’s End (PC) requires AVX2 support.
• CPUs without AVX2 (e.g., Intel 2nd–4th Gen like i7-3770, i5-2500; some AMD FX and early Ryzen?) crash on launch or fail to load.
• Error examples: “This application requires AVX2” or instant crash.

✅ Most modern CPUs (Intel 6th Gen+ / AMD Ryzen 2000+ or newer) support AVX2.
❌ Old Intel Sandy Bridge, Ivy Bridge, Haswell (some early), and some AMD pre-Ryzen lack AVX2.
