Uncharted 4 — Avx2 Fix _verified_
CPUs without native AVX2 support are likely to handle the game's high-demand tasks less efficiently. This can lead to lower FPS and stuttering during busy scenes.
A common cause of crashes is outdated drivers. Download the latest drivers for Nvidia or AMD.

Intel Core i7/i5/i3 processors from the Ivy Bridge (3rd Gen) era or older. Intel Pentium and Celeron budget chips. AMD Phenom, FX-Series, or early APUs. Step 1: Check Your Official Game Version uncharted 4 avx2 fix
The is a community-made software patch that allows the game to run on older CPUs lacking Advanced Vector Extensions 2 (AVX2) support. When the Uncharted: Legacy of Thieves Collection launched on PC, Naughty Dog made AVX2 instructions a strict hardware requirement. Consequently, players using older but otherwise capable processors—such as Intel Ivy Bridge, Sandy Bridge, or first-generation AMD Ryzen chips—experienced immediate crashes to desktop on startup. To bypass this hardware limitation, modders developed an unofficial fix that translates or emulates these instructions, allowing the game to boot successfully.

Not sure if your processor is affected by this issue? Here are three easy ways to check: CPUs without native AVX2 support are likely to
| Method | Resolution | Avg FPS (Jungle Level) | 1% Low FPS | Stability | | :--- | :--- | :--- | :--- | :--- | | No fix | 1080p | Crash on launch | N/A | 0/10 | | Intel SDE (Method 1) | 720p (Low) | 28 FPS | 18 FPS | 7/10 (Micro-stutters) | | Modded EXE (Method 2) | 1080p (Medium) | 42 FPS | 31 FPS | 8/10 (Occasional crash) |
Uncharted 4 AVX2 Fix: How to Play on Older CPUs (Legacy of Thieves)
The game typically crashes during the initial handshake with the CPU or during specific mathematical calculations (physics/rendering) that utilize __m256 registers. u4.exe or u4-l.exe . Download the latest drivers for Nvidia or AMD
The most important "fix" for the Uncharted 4 AVX2 issue is to .
: Occasional frame drops during heavy combat or cinematic transitions. Longer Load Times : Shaders may take much longer to compile.
This method does not emulate; it simply deletes the CPU check. The game may behave unpredictably (random physics glitches, audio popping) if it tries to use an AVX2 instruction that doesn’t exist. However, it offers native performance.
The culprit was a single, missing line of modern architecture: AVX2 (Advanced Vector Extensions 2).
