Currently 0 A.D. performance is lower than that of similar RTS games, especially when playing with many units on a map. This page collects some tasks and suggestions to improve performance of pyrogenesis, the engine used by 0 A.D.. To discuss other performance related ideas you can use the Performance Optimizations forum thread.
