Uncharted 4 Avx2 Fix [extra Quality] Jun 2026

Under the tab, ensure your game is set to "Always keep this game updated."

: Drag and drop the extracted emulator files (usually including an sde.exe or a custom modified .exe / .bat starter script) directly into the main folder alongside u4.exe .

Nathan Drake stood on the edge of the cliff, staring at the Libertalia ruins—but for

While official patches resolved this for many players, community-made AVX2 bypass fixes remain essential for gamers using older hardware or specific emulation layers. Here is the complete guide to understanding, installing, and troubleshooting the Uncharted 4 AVX2 fix. Why Uncharted 4 Crashes Without AVX2

Using emulators may result in lower performance and slower frame rates. uncharted 4 avx2 fix

Original (AVX2) | Replacement (AVX/SSE) | Count in executable --- | --- | --- VGATHERDPS ymm0, [rax+ymm1*4], ymm0 | Scalar loads + VINSERTF128 loop | 127 occurrences VPADDD ymm0, ymm1, ymm2 | VPADDD xmm0, xmm1, xmm2 (high/low parts) | 1,203 occurrences VPERMPS ymm0, ymm1, ymm2 | 2x VPERMILPS + shuffle | 89 occurrences

Within 72 hours of the game’s release, a Russian modder on GitHub released a custom version.dll or winmm.dll proxy. This method is cleaner than SDE because it patches the game’s import table to skip the AVX2 check entirely.

The most important "fix" for the Uncharted 4 AVX2 issue is to .

Following widespread user feedback regarding hardware accessibility, the developers released official post-launch patches aimed at improving compatibility. These updates minimized the game's strict reliance on AVX2 instruction sets during startup. Under the tab, ensure your game is set

CPU microcode and Windows power plan

Run game as Admin and disable overlays

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.

The Uncharted 4 AVX2 fix is a testament to the PC gaming community's refusal to let good hardware go to waste. While it isn't a perfect solution, it allows players on legendary older chips to experience Nathan Drake’s final adventure without needing a total system overhaul. Why Uncharted 4 Crashes Without AVX2 Using emulators

The strict AVX2 requirement in Uncharted 4: Legacy of Thieves Collection initially locked out owners of older, high-end PC hardware. Thanks to official developer optimization updates and community-created translation libraries, you can successfully bypass this restriction. By installing the appropriate community file or utilizing emulation tools, your legacy rig can still accompany Nathan Drake on his final globetrotting adventure. If you want to fine-tune your setup further, let me know: Your exact Whether you are using the Steam or Epic Games version The exact error message you see if it still crashes

: Users with older hardware report that while the game now launches, performance can be a mixed bag. Some users on 10-year-old CPUs found it "smooth as butter" or "playable" at 60 FPS, while others noted that shaders still cause high CPU temperatures and potential micro-stutters if not fully compiled. No Impact on Modern PCs

Because on paper, the Legacy of Thieves Collection lists an Intel i7-4770 (Haswell) as the minimum requirement. That chip supports AVX2. However, many gamers with perfectly capable CPUs—like the Intel i7-2600K (Sandy Bridge), i7-3770K (Ivy Bridge), or AMD Phenom II —found the game refused to launch. These chips are fast enough to run the game, but lack the specific instruction set.

This guide explains why Uncharted 4 can crash or fail to launch on some PCs due to AVX2 instruction issues, and gives a clear, step-by-step set of fixes you can try. I assume you’re running the PC version on Windows.
