Game studios often compile with /arch:AVX2 in MSVC for vectorization and enable Intel IPP libraries that assume AVX2. Adding runtime dispatch increases QA complexity. Iron Galaxy likely prioritized performance for the majority of modern CPUs. Check quickly:
We diffed the original and patched game executables (binary diffing using Diaphora). Identified replaced AVX2 instructions were mapped to equivalent AVX or SSE sequences. CPUID interception via DLL injection was verified. Supported: Intel 4th gen (Haswell) and newer, AMD
