Before we unleash our creations to the world, it is very important to always be aware of our game's performance and how it will affect your player's experience. CryENGINE has a variety of different, built-in debugging and profiling tools. As you will soon find out, some of them are specific to certain subsystems and are useful for advanced users of the technology. Other tools, however, are very useful for most engine users in their regular, daily workflow. The next section lists the profiling CVARs and commands that each programmer, artist, and level designer working with CryENGINE should know.
The proverbial first line of defense for developers in terms of profiling and reading performance in Sandbox is the display info CVAR. This is activated and displayed in most cases by default; however, we will discuss how to enable it as well as explore some of the values it is communicating to you.
