Arkham City (BatmanAC.exe) stopped with Unreal's "Fatal error!" about 1.5 s after start: an access violation in BatmanAC.exe right after steam.dll loads. The game leans on x87 and needs full precision under FEX (FEX wiki), while the default FEX preset sets FEX_X87REDUCEDPRECISION=1. Engine fixes sit above the shared preset and below the player's own game profile, so a fix keyed on BatmanAC.exe beside the started exe (BatmanAC.exe or BmLauncher.exe) restores x87 precision for this game only. Arkham Asylum, which shares BmLauncher.exe but not BatmanAC.exe, keeps the preset.
