vsync causes stuttering in MGS: TTS

[drhycodan]

Vsync is causing stuttering in a number of games, but MGS suffers from it more so than other titles.  This issue didn't use to exist back when Dolphin was still using borderless fullscreen where I can just leave vsync off in Dolphin and still experience no screen tearing.  How is it possible that I get better performance with borderless fullscreen than with exclusive fullscreen?  Is there any way to implement vsync like it was with borderless fullcreen (or windowed) into exlusive fullscreen so I won't get the massive stuttering with vsync and with the speed improvement of exclusive fullscreen?

Does this even happen in the latest dev build: https://dolphin-emu.org/download/ (4.0-5222 as of writing)?
