Can anyone tell me what the purpose of the maximised borderless window option is in games? I've noticed it in a few games lately. Seems to be on by default in Grey Goo and I think I saw it in Thief too.

Also, for whatever reason some games it just seems to take less resources to do that. I know Skyrim get's a noticeable performance boost when doing it.
