if (timeDelta>.02)
{ // do stuff
ptr_display(timeDelta);
lastTime = currTime;
}
else
{ // wait to do stuff
::Sleep( currTime -lastTime );
}

Just call Sleep in your main loops. It takes 1 parameter which is the number of milliseconds to sleep. Even passing it a 1 will make a HUGE difference without really impacting on your program. You can even pass it 0 if you like, to only give time to threads of a higher priority class.
