--- Begin Message ---SDLx::* is still in the stages of being too slow to use. We have not optimized the SDLx::Validate in it.You can mix with SDL::* to improve your performance, if you are confident of the validation. Another things you can do is keep track of what 'LED' changes, and only update that rect. SDL::Video::update_rects( ( SDL::Rect->new(x,y,w,h), .... ); I have attached an updated script.
