On November 16, 2022, developers and Naughty Dog released Patch v1.3.20812 to resolve the issue.
If you are still experiencing issues, ensure your game is updated to the latest version via Steam or the Epic Games Store. If you are on an ARM-based Windows PC, the October 2025 Windows 11 update introduced , which enables AVX and AVX2 emulation, further expanding compatibility for modern non-x86 hardware.

The search for an Uncharted 4 AVX2 fix became a digital scavenger hunt typical of the PC gaming ecosystem. Unlike a standard bug which requires a developer patch, an instruction set incompatibility is a fundamental architectural mismatch. The "fix" isn't a simple settings toggle; it usually involves an emulator or a CPU patch that intercepts these illegal instructions. uncharted 4 avx2 fix
The launch of Uncharted 4 on PC was marred by this issue, with players flooding forums to report the "unsupported CPU" error. The immediate reaction was one of bewilderment, especially as other demanding titles ran perfectly fine on their older hardware.
Before diving into fixes, you need to understand the enemy.
: Uncharted 4 was built for the PlayStation 4, which uses a Jaguar CPU that does not support AVX2. On November 16, 2022, developers and Naughty Dog
This method often results in extremely poor performance (7–15 FPS) and frequent crashes.

This issue is almost always tied to instruction set requirements. If your CPU lacks AVX2 support, the game engine cannot execute its code, causing an instant crash. Understanding the AVX2 Requirement Intel Core i7/i5/i3 processors from the Ivy Bridge
stands for Advanced Vector Extensions 2 . In simple terms, it's a specialized set of instructions built into modern CPUs designed to handle complex mathematical calculations more efficiently. While helpful for performance, the problem arises when a game like Uncharted 4 demands this feature.
Playing Uncharted 4 without native AVX2 support is a compromise. You may encounter longer loading times and occasional physics glitches. However, for fans stuck on legendary hardware like the i7-2600K or i7-3770K, this fix is the only way to experience one of the best stories in gaming history.
Older CPUs may take much longer to compile shaders on the first launch. Bottlenecks:
: Extremely poor performance (often 7–15 FPS) and frequent crashes.
: Users with modern CPUs (4th Gen Intel/AMD Ryzen and newer) continue to use the standard AVX2-enabled executable, ensuring they benefit from the faster instruction sets without any performance penalty from the legacy support.
