改分辨率后加入循环地图脚本如何防卡顿？？

doubyen

目前遇到的问题，在扩展分辨率后，我使用了 循环地图 v1.0 by 叶子 @66rpg天空工坊 的循环地图脚本，使地图左右循环；
现在唯一的问题是游戏运行卡顿，问题基本出在新插入的 LM Spriteset_Map里的脚本：
#==============================================================================
# ■ Spriteset_Map
#------------------------------------------------------------------------------
# 　处理地图画面活动块和元件的类。本类在
# Scene_Map 类的内部使用。
#==============================================================================

class Spriteset_Map
  #--------------------------------------------------------------------------
  # ● 初始化对像
  #--------------------------------------------------------------------------
  alias initialize_leav_loop initialize
  def initialize
    initialize_leav_loop
    # 生成角色活动块
    if $game_map.horizontal_loop
      for i in $game_map.events.keys.sort
        @character_sprites.push(Sprite_Character_Loop.new(4, @viewport1, $game_map.events))
        @character_sprites.push(Sprite_Character_Loop.new(6, @viewport1, $game_map.events))
      end
      @character_sprites.push(Sprite_Character_Loop.new(4, @viewport1, $game_player))
      @character_sprites.push(Sprite_Character_Loop.new(6, @viewport1, $game_player))
    end
    if $game_map.vertical_loop
      for i in $game_map.events.keys.sort
        @character_sprites.push(Sprite_Character_Loop.new(2, @viewport1, $game_map.events))
        @character_sprites.push(Sprite_Character_Loop.new(8, @viewport1, $game_map.events))
      end
      @character_sprites.push(Sprite_Character_Loop.new(2, @viewport1, $game_player))
      @character_sprites.push(Sprite_Character_Loop.new(8, @viewport1, $game_player))
    end
    if $game_map.horizontal_loop and $game_map.vertical_loop
      for i in $game_map.events.keys.sort
        @character_sprites.push(Sprite_Character_Loop.new(1, @viewport1, $game_map.events))
        @character_sprites.push(Sprite_Character_Loop.new(3, @viewport1, $game_map.events))
        @character_sprites.push(Sprite_Character_Loop.new(7, @viewport1, $game_map.events))
        @character_sprites.push(Sprite_Character_Loop.new(9, @viewport1, $game_map.events))
      end
      @character_sprites.push(Sprite_Character_Loop.new(1, @viewport1, $game_player))
      @character_sprites.push(Sprite_Character_Loop.new(3, @viewport1, $game_player))
      @character_sprites.push(Sprite_Character_Loop.new(7, @viewport1, $game_player))
      @character_sprites.push(Sprite_Character_Loop.new(9, @viewport1, $game_player))
    end
    update
  end
end

我查看了本站的帖子，唯一防卡顿的帖子并不针对扩展分辨率，所以急需各位大神帮忙，解决一下问题~~~
附件里有我的工程文件，请帮助修改，并备注修改方案

卡顿是电脑配置问题，这个脚本没有任何问题
