I don't disable VSync for FPS. I disable VSync because it reduces input lag.

The input lag can be a serious issue with certain monitors and video cards. It's very noticeable to me when playing and FPS.

Agreed. Overwatch in particular has felt a lot more snappy since disabling it. I'd been out of FPSes for a while, but that game made me acutely aware of it.

You should try vsync with triple buffering and make sure to set:

flip queue size / max pre-rendered frames to 1 (depending on AMD/Nvidia)

Most games I play these days are DirectX 10+, which seems to preclude the use of the pre-rendered frames setting.
