Full screen is NOT full screen. It is "make the black boarder around the play area bigger mode". Full screen would increase the number of pixels on the play area to fill the screen. It would take longer to compute each frame, but it would also allow a person to make bigger things.
Full screen mode as it exists now is COMPLETELY USELESS. I've NEVER used it in the ENTIRE TIME it's been an available option. I always use window mode, as there is absolutely no advantage to the current implementation of full screen mode. It's just a waste of space on the options menu. (and it allows the TPT developers to falsely advertise that their product has a full screen mode, and partially be telling the truth)
