Mostly later because I can alt+tab and look up meta-game info when necessary. This means that other windows will no longer annoy you by masking the window you need to see as you work. They are almost always in fullscreen or windowed fullscreen. Thanks for the reply, that's exactly what I get exiting full screen with ALT-TAB, I get to a windowed but borderless game window occupying full screen but I can hover around and un-hide taskbar and toggle around the other windows, I use it sometimes - coupled with a small software called Chameleon windows manager'( that has cool features like forcing stay-on-top) to have couple of small monitoring applications windows I drag to the corner of the screen staying always visible on top of the game window at a pseudo-full screen which is pretty neat for monitoring while on single monitor, but I think since it's not a true full screen, some game graphics settings would not be applied. Just click on the Stay Always-on-Top button or use a hokey (Win+S, by default) and Actual Title Buttons will keep that particular window on top of all others. The game you're running - probably newer one- might have a dedicated windowed bordeless mode shortcut through ALT-ENTER or CTRL-ENT, either through game itself options or through the gaming software overlay (steam or origin) or even through graphic card software ( radeon and nvidia), not to mention other third party programs for game steaming etc like overwolf: a bit confusing.
