P1na: Oh, so that's what the horrible full screen monstrosity I had to alt+F4 out of was. It popped out of nowhere and it had me quite puzzled, I must have activated it by mistake.
Personally, I only have a laptop and game on it.
Hahahaha, that was my first encounter with it as well. I got into it by accident and couldn't figure out how to get out of it and went into rage-quit mode myself. Eventually I switched to it one day on purpose to actually see what usefulness it might provide (to anyone not just to me) and I concluded that it was interesting and minimalist and that it would best suit people on a TV using a controller etc. and that they had made it for console gamer type folks. I also patiently figured out how to get out of it properly without rage too and then slapped myself for making it more difficult than it needed to be. hehe.
So I can see it has its uses for some folks but overall it's not so useful to me. I'd much rather game on a 30" 16:10 display 16-18" away from my face at 2560x1600 resolution than on my 65" TV 16:9 several feet away from my face at roughly 1024x720 or whatever its effective resolution is (rear projection CRT from 2004 era).
I bet there are a lot of others out there that have accidentally entered big picture mode and then went into an angry rage too though. LOL
