Flash Vs Director... mmmm

Hi,
I’m making a game, a tile based game. I make that in flash mx, and i don’t like the results in speed, it goes slow, bicouse the map is large. Now… I heard about Director, and his good manage of images… Is that true?

For making games… it is better to learn Lingo and making with the Director?

PD: I’m installing rigth now the Director on my PC… jeje.

OK.
