When my game is the active window the CPU usage is ~50%. When the window is not focused, CPU usage is 99%. My target frame rate is 200, but since the window is not focused Display.sync is never called. Suggestion: move Display.sync out of "if (hasFocus() || getAlwaysRender())". This change makes CPU usage ~13% when the window is not focused.
