Why does Alt - Tab into a fullscreen game take so long?

[ZeroTroubles]

I never really thought about this; but why does alt-tabbing into a fullscreen game take so long?
With my two monitors, it's truly annoying to have games be in fullscreen as when I click on the other monitor first everything will go black, and then the monitors have to reset to a different input etc...
Why does it take so long? Why can't it just do it like fullscreen borderless windowed games do? Is there any way to fix this?
I want to stay fullscreen because of brightness settings in CS:GO but also ShadowPlay only works on fullscreen games for some reason. Then again, I really hate fullscreen because it takes way too long to switch from Chrome to my Game and back

Graphics card mode switch often takes a rather long time. Depending on how much RAM you have
there might be swapping going on when switching in and out of game.

Run the game in compatibility mode for Windows 7 😉

Try Alt + Enter
