Between Window and Full Screen

I figured as much, but you gotta admit, jeez for a game that's 2D and was made for 12 year olds the requirements are damn high and misleading compared to what's read in the Nexon site. It's nothing compared to the bare minimums. I don't understand how it could require that much effort. I've played Guild Wars and it runs better at times than Maplestory in window mode.

Speaking of which, if you remember it runs fine on full screen and only gets problems when alt+entering to window mode. Does window mode just intentionally burn more memory?
