I have found OcempGui very useful so far, the very detailed documentation is of great help for me, and the Gui is very clean, so big thanks to his creator.

Nevertheless I have reached a point where speed of display is getting problematic to me, mostly when I update an imagemap covering half of the screen. Even if my game is a turn by turn game, updating the whole imagemap takes up to 1/3 of a second on my computer, and it is slower than a natural keypress.

Are there any advices to increase my display speed ? I noticed that if I use an Image instead of an Imagemap, there is a slight increase of speed, but I'd prefer sticking to Imagemaps, as I use their click detection.

You can have a try at my in-dev game if you want, any feedback would be welcomed to me :
