I tried the default mechanism (everything works automagically letting DXGI do the work as i specify in MakeWindowAssociation
However that's "really" slow, i doubt it's reloading the ressources that is slow (i'm only using 1 mesh, albeit large & a single texture, drawing a single object, nothing fancy here). It's taking a solid 4-5 seconds to switch from or to fullscreen mode!
While not crazy this does seem very slow to me, is there an alternative that could ideally get me <1sec times at least? I'm only targeting DX11.2 so no need for the alternative to be backward compatible, i'll take anything
