Environment variables

Variable Meaning
LINUWUX_DEBUG=1 Verbose [linuwux] logs (game process; helpers stay quieter on current builds)
LINUWUX_REDIRECT_ALL=1 Also apply SIGSYS/CPUID handling inside Wine’s usual system RIP range (debug)
PROTON_AVX=1 Influence CPUID/AVX-related spoof details (see library behaviour)
PROTON_DISABLE_LSTEAMCLIENT Defaulted to 1 by the library if unset
WINEDLLOVERRIDES Library appends winmm=n,b, version=n,b, reflex=n,b, reflex64=n,b when missing
LD_PRELOAD Must include liblinuwux.so for the game process; prefer the linuwux wrapper so append is handled
LINUWUX_PRELOAD Optional path override for the wrapper when finding the .so
