yes, is there any way to calculate this value?

on onEnterFrame(event)

function onEnterFrame(event) local fps = 1/event.deltaTime print(fps) end

If you're using an iPhone, and run the GiderosiPhonePlayer from Xcode with the iPhone plugged in, it shows fps on the debug console.

I don't know if there's the same facility with Android.

Thanks GregBUG
If i build and run project from eclipse, i can see fps in logcat

Hi,

The fps seen in Xcode console and logcat uses a algorithm like:

local frame = 0 local timer = os.timer() local function displayFps() frame = frame + 1 if frame == 60 then local currentTimer = os.timer() print(60 / (currentTimer - timer)) frame = 0 timer = currentTimer end end   stage:addEventListener(Event.ENTER_FRAME, displayFps)

(It's same with @GregBUG's but averaged through 60 frames)

thanks @atilim
