Steam News announces the automatic availability of the promised new update for Empire: Total War, which brings the real-time strategy sequel to version 1.3. Also now available is the Empire Total War: Elite Units of the West DLC for the game, which adds 14 new units to single player and multiplayer games for a $3.49 price tag. The patch also adds 14 new units for free, which replace their generic equivalents that came with the game. Also included in the patch are bug fixes, balance changes, and promised performance improvements, as described here: "This update includes the implementation of multi-threading in the game for multi-core processors and many optimizations that will also help increase performance on single core machines. Players will see huge benefits through increased frame rates particularly in land and naval battles."
