> translating x86 code to x86 code My understanding is that it doesn't do any of this. Windows programs generally don't make direct syscalls, they're undocumented and only used by Microsoft-written DLLs. Wine provides a re-implementation of these DLLs suitable for Unix-like systems. The code of the program itself is untranslated and runs as-is with no performance loss.
