@Matty,
How much overdraw are you getting to make a z buffer worthwhile for a 2d game?
I don't think BlitzMax has as fast individual pixel plotting functions as BlitzPlus - which I really need for my isometric game which uses pre rendered scenes and a pre rendered z-buffer to test each pixel against as to whether it should be visible or not.
