23a:Frames per second

From Dwarf Fortress Wiki

This article is about an older version of DF.

Frames per second (frequently abbreviated to FPS) is a measurement of how many steps per second the program runs at.

A step is not one step of a dwarf, but one screen advancement of the game, like animation, moving forward one minimum increment of game time. As an example, a dwarf with default agility can move one square every 10 steps. So with 100 FPS you will see your default agility dwarves be able to walk 10 squares in one second.

To view your frame rate, open your init.txt file, scroll down to [FPS:NO], change it to [FPS:YES] and save the file.

You can also configure the maximum framerate using the [FPS_CAP:x] setting, allowing a young fortress to progress much more quickly. On some systems, increasing this beyond your monitor's refresh rate may have no effect - if this is the case, you may need to disable VSync in your video drivers. Alternatively, the following patch for version will automatically disable VSync on program startup:
