Returns

number fps
The current FPS.

The returned value is the number of frames rendered during the last second, rounded to the nearest integer value.

It is one divided by what love.timer.getAverageDelta returns, otherwise known as the reciprocal, or multiplicative inverse of it.

To get instantaneous frame rate values, use 1.0 / love.timer.getDelta(), or 1.0 / dt if in love.update, with dt given as the parameter.

Examples

Display text at the top left of the screen showing the current FPS.

function love.draw()
   love.graphics.print("Current FPS: "..tostring(love.timer.getFPS( )), 10, 10)
