inside 3 seconds i have a min-max frame delta about ~12 frames and more!?
( because this my game run not smooth :-( )

can someone confirm ?

I not quite confirm it.

I added a maximum delta display, after allowing 10 seconds for the FPS to get up to initial speed.

Results on five Android devices (after 10 second warmup and 10+ seconds delta check):
Amazon Kindle Fire HD 7" OS 4.0.3 - max delta < 1.5
Nexus 7 OS 4.2.2 - max delta < 1.8
Philips GoGear Connect 3.2 OS 2.3.3 - max delta < 2.4
Samsung Galaxy S III OS 4.1.1 - max delta > 8.5 < 9.0
Toshiba Thrive 7" OS 4.0.4 - max delta < 3.9

After being left to run for several minutes, the Kindle was up to 3.17 as max delta.

The Samsung is the only one that had a big delta. But not as big as you indicate.

@Ancient Lady
thank you very much.
yes,your samsung s3 is very strange.

i using a odys tablet express pro.
i thought about a running background service that anger me,
but also i tryed ending all background software and saw no improvement.

a new example with a chart:

+ Code Snippet

rem
rem AGK Application 1.08 Beta 18
rem Frame Impact Chart

setorientationallowed(0,0,1,0)

TestFPS()
end

function TestFPS()

    dim FPS[200] as float

    t#=timer()

    i=0
    do

        if getpointerpressed()=1
            exit
        endif

        FPS[i]=screenfps()

        i=i+1
        if i>200 then i=0

        print("FPS")
        print(screenfps())

        print("Frame Time")
        print(getframetime())

        for in=0 to 200
            v#=FPS[in]
            x#=in
            x#=x#/2.0
        drawline(x#,100.0,x#,100.0-v#,255,255,255)
        next

        Sync()
    loop

endfunction

It's not just the Samsung Galaxy S III. But we don't know what combination of OS, display hardware and other things it is that causes some of the issues seen with the EnableClearScreen(0) usage.

While you might be killing lots of background stuff, the core OS is going to be doing all sorts of things and they may affect the FPS seen.

I am currently trying to deal with the different FPS provided by different devices and how it affects the timing of my WIP.

the only thing i can do is deinstall all apps and look
what happens.
because its not affect all devices i thinks it is not a agk problem.

this chart was without killing running apps.
with killed apps it looks same.

i think its a result from overload.
i reduce the sync rate to 40 fps, then its constant at my tablet.

Markus, just a thought but have you turned power saving off? That disables half the CPU cores, and my own app runs fluid at 60fps normally, but with power saving it varies from 34-42 - and that's a Samsung Note 2.
