title: Sprite Kit Serious FPS Issue In Full Screen Mode on OS X
body: <p>I'm making a fairly complex sprite kit game. I recently added support for OS X. I get 60 fps always, regardless of how my game is scaled when the window is resized (even when resized to max screen space). However, the moment I make my App enter "Full Screen," the fps drops to 30-40 fps and stays that way? But if I take my mouse cursor and reveal the menu bar while full screen is enabled, the fps goes back up to 60 fps! </p>
  
  <p>You can even test this bug by making a sprite kit game for mac in Xcode using the default template. Here are the screen shots I took of the default game template for mac.</p>
  
  <p>I suggest trying it out for yourself, you don't even have to write any code if you use Apple's default sprite kit template for OS X.</p>
  
  <p><strong>Max Window (No FPS Problems: 59-60 FPS)</strong>

  <p><strong>Full Screen Mode (FPS Drops to 30-40 FPS)</strong>

  <p><strong>Full Screen Mode With Mouse At Top Revealing Menu Bar (Surprisingly, NO FPS Issues: 59-60 FPS)</strong>

  <p>Anyone have any idea what might be causing this problem. I don't want to release my App with full screen mode if it means users will <em>lose</em> performance. You would think full screen mode could better optimize drawing but apparently it's quite the opposite. I'm running this on Yosemite.</p>
