Uncharted 4 Avx2 Fix Official

Uncharted 4 strictly requires Windows 10/11. The community DLL will not make it work on Windows 7 due to DirectX 12 Agility SDK requirements.

Note: This method is extremely unstable and requires constant reapplication. It is not recommended for first-time fixers. Before you spend three hours tinkering with Intel SDE, ask yourself what CPU you actually have. uncharted 4 avx2 fix

| CPU Generation | AVX2 Support? | Expected Experience | | :--- | :--- | :--- | | | No | Playable via SDE/Fix, but expect 30-40 FPS on Low/Medium. | | Intel 4th Gen (4xxx) & newer | Yes | Game works natively. No fix needed. | | AMD FX-Series (8350, 6300) | No | Extremely poor performance even with fix (architectural bottleneck). | | AMD Ryzen (1xxx, 2xxx, etc.) | Yes | Works natively. | | Old Xeons (E5-2670 v1/v2) | No | Great potential with the DLL fix. Xeons have the muscle, just lack the instructions. | Uncharted 4 strictly requires Windows 10/11

When the game tries to call an AVX2 instruction and the CPU doesn't understand it, the application fails silently (or with a generic "Unhandled Exception" error). Here is the harsh reality: There is no official patch from Naughty Dog or Iron Galaxy (the porting studio) to remove the AVX2 requirement. It is not recommended for first-time fixers

Even though Uncharted 4 has no invasive anti-cheat, Steam’s "Steam Input" overlay can conflict with the proxy DLL. Disable the Steam Overlay for this game.
