Windows 10: Why does DWM force triple buffering and v-sync in windowed games?

It has just come to my attention that Windows 10 forces triple buffering and V-sync in windowed and borderless-windowed games via Desktop Window Manager. This is baffling to someone who plays latency critical games regularly and uses dual displays, though I would imagine it could also bother Windows gamers who use single displays, as alt tabbing from full screen is more disconcerting than from windowed, as it takes significantly longer and causes the game window to sort of flash a blank screen somewhat alarmingly every time


Please remove this feature and change it back to how it was when, I'm told, it was disable-able

:)

 

Borderless Gaming and forced Vsync/Triple Buffering

It's a known issue and it does force triple buffering,

common problem with 8 and 10. You can see the difference by switching from full to borderless

Oops - I went to check BF4 (using borderless) and did about 20 re-writes and didn't notice you had posted back

(scatter brain poster ).

I very much doubt V-sync or Triple buffering is being forced.

( Apparently V-sync can cause a bit of input lag, but Triple Buffering is supposed to sort that out)

If you are not seeing high cpu use from DWM in Task Manager while playing I don't think it would be
the cause of the lag either.

My understanding is FPS and input lag aren't directly related. Are you using the same monitors and cables

as when you were using Win7 ?

Other than input lag via the monitor, I don't know what the cause would be, and again,

I wouldn't really notice a slight delay in the mouse. My reactions are not young enough .

Its weird I'm also using a 980gtx and I have no fps issues whatsoever it's just a really slight input delay on the mouse

it feels like forced sync or triple buffering

problem goes away in fullscreen
