After the update, players on "legacy" processors have reported the game running at stable framerates (e.g., 40–60 FPS depending on the GPU), whereas it previously wouldn't launch at all. Alternative Workarounds (If Patching Isn't Possible)
The "Uncharted 4 AVX2 fix" issue is a classic PC gaming parable, demonstrating the delicate balance between pushing for higher performance with modern CPU instructions and ensuring broad compatibility for the diverse range of hardware in the PC ecosystem. While the initial requirement was a frustrating and arbitrary barrier for many, it was quickly resolved by an official patch.
Run the game executable through the emulator using the following command structure: sde.exe -- u4.exe (replace u4.exe with the exact path and name of the Uncharted launcher executable). Potential Risks and Performance Expectations uncharted 4 avx2 fix

Use a library like AVX-512 Emulator or Intel's XED to parse the binary at runtime. The Logic:
This method significantly reduces performance. You will likely experience stuttering and lower framerates, as your CPU is doing heavy translation work in the background. Run the game executable through the emulator using
Intel 4th gen (Haswell) and newer, AMD Ryzen and some late FX. Not supported: Intel Core 2 Duo, 1st–3rd gen Core (i7-9xx, i7-2xxx, i7-3xxx), AMD Phenom, Bulldozer (unless Excavator variant).
From a developer’s perspective, disabling AVX2 means rewriting low-level math libraries and recompiling the game engine, which could introduce performance regressions for the 99% of users who do have AVX2. In short, they won't do it.
