Not a full download of the video card with vsync.

In some games in fullscreen mode with vsync vidyuhi uploaded by 70% and fps at level 40-45. Should switch to windowed mode, any window without a frame, for example, from 100% loaded and 60 fps.
It was in 1070, and now 1080ti. The Windows 10.
I would be played in windowed mode, but HDR only works in fullscreen.
