7. Conclusion

The Uncharted 4 AVX2 fix successfully enables gameplay on pre-AVX2 processors via instruction emulation and CPUID masking. Performance degrades by 25–40% compared to native AVX2 hardware, but the game remains playable at lower settings. The fix represents a valuable case study for extending software compatibility without source code access. As instruction set extensions proliferate, community patches will play an increasing role in digital preservation. The game’s requirement for the AVX2 (Advanced Vector
