Python Pygame中的大滞后

我在弗雷迪家玩了五个晚上的游戏，我所有的一切都正常运转。问题是当你按下灯按钮时有一个延迟。当你向左或向右移动时，也有一个非常轻微的延迟（在我添加灯光功能之前的版本中我没有注意到）。我感谢你的帮助

以下是我的代码的简化版本：

building_map = pygame.image.load('images/map.png')
building_map.convert_alpha()
camera_switch = pygame.image.load('images/camera_switch.png')
turn_left = pygame.image.load('images/turn_left.png')
turn_right = pygame.image.load('images/turn_right.png')
turn_left.convert_alpha()
