I understand that when working with the LCD drive on the Ti-83+ directly, you get immediate updates. Is there a way to control when these updates occur (meaning the screen doesn't update everytime you draw a single point)? If not, what's the advantage to using the RAM over plotsscreen?
For larger tasks like a tile mapper, you can let your tile mapper work during the delay. You actually gain speed by not wasting time in doing nothing between writes. (Note that normally a good tile mapper like dwedit's, jim_e's or calcmaniac84's copy the old screen to lcd and compute the new screen that will be copied in the next frame.)
We control when the LCD updates by copying plotsscreen to the lcd ram when we need

Is it natural, or does it involve interrupts or another process
If the LCD was accessed directly, would this cause cross-compatibility issues between each hardware revisions of the 83+, 83+SE and 84+? I think the used LCD is different over the time
