Which is causes more lag, fullscreen or borderless?

Sorry if it's a dumb question, I just want to know if one is less laggy than the other or if there is no difference.

Exclusive Fullscreen is generally considered to be more efficient and smooth.

It's not a dumb question, but the answer is not so straightforward since Windows 11 /DirectX 12 and its new "flip presentation model" (it must be enabled in Settings > Display > Graphics > Default Graphic Settings). This model is specific to borderless window gaming and apart from fps now being (usually) on par with exclusive mode, issues like screen tearing are less of a problem. So you find yourself enabling vsync far less.

With modern DirectX11 or DirectX12 games, it doesn't really make a difference these days.
