TIPS

Figure out your minimum spec PC or Hardware.
Build and profile your game for each console early in development.
Give your team enough time to add optimization support/switches for materials, lights, fog, LODs, and other GPU-related content.
To help manage and maintain performance, set up content guidelines.
Set up nightly builds and level cameras to help capture overall performance.
Avoid testing performance in the game editor; profile a standalone game build.
