1. Will this give me an accurate frames per second reading?

private void clockPanel_Paint(object sender, PaintEventArgs e)
{
   fpsCounter++;

   if ((DateTime.Now - lastFrame).TotalMilliseconds >= 1000) // 1 second elapsed
   {
      fpsString = fpsCounter.ToString();
      lastFrame = DateTime.Now;
      framecounter = 0;

3. quite a bit happens in calculateAndUpdateDrawingVariables(); and it runs 100times per second(animationTimer = 10ms). Any tips on what to avoid in a method like this that runs so many times to use less CPU power?
