CPU core throttling

I keep getting throttle problems


Where an app goes slow and then speeds up to double and then goes slow again.


I noticed it mostly happens when Anti-Virus and MS-Defrag are running, but it also happens at other times when no background stuff is running.


In my animated programs i had to put timing / loop-counters in to control the pulsing, like below.






  (   program stuff here  )




    'get fastest loop time the computer does.

    if time_min = 0 then time_min = time2-time1

    if time2-time1 < time_min then time_min = time2-time1

    if time2-time1 > time_max then time_max = time2-time1

    time_avg = (time_min+time_max)/2

    time3 += time_avg



    'get number of loops in quater second.

    if time3>=.25 then

        for a as integer = 1 to number_of_balls

            balls(a).speed = ( (balls(a).radius*2) / (loop_count) ) ' change radius*?? to adjust speed




    end if


Loop Until Inkey <> ""



I use FreeBasic for doing my programs.


I've got my power options set to "max power usage" when plugged in, and still i'm getting throttle pulsing problems.


I've got a Compaq Presario CQ60-210 US Notebook PC

AMD Athlon X2 64 ,  Running Windows 7 64 bit with 4 Gig of Ram.


Is there a know problem with other people reporting throttle pulsing ??
