Is it possible to turn V-sync off in Windows 10 for windowed games? It wasn't possible in Windows 8/8.1 so I had to downgrade to Windows 7 which in I could simply change the theme to Aero basic which has V-sync turned off.
I play most of the games in windowed/borderless mode, so graphic cards' application can't do anything about V-sync. (turn it off or on.) In Windows 8 you can't turn DWM off (Desktop Window Manager?) which keeps V-sync on all the time.
