The new version has the awesome feature of using your GPU for processing instead of your CPU so that super hd stuff doesn't rape your CPU anymore, but it is full of bugs.
--When I open CS, it crashes. --When full screen, when it moves to another item on the playlist, it doesn't stay maximized (adds a window title border to the top and part of the start bar shows up) --When not fullscreen, it doesn't resize the window so that the next file on the playlist opens at its true resolution if not maximized --It won't disable the screensaver when the option is on (though I had this problem in other releases, too).
