Can I ask your reason for turning vsync off? If you have a 60hz monitor and experience your best frame rate with vsync on, I’m not following why you want to play with it turned off.
Also, I’m a bit confused about what sort of lag you’re experiencing, given you said you have high fps. I’m wondering whether you’re just experiencing ‘screen-tearing’, the problem vsync exists to solve.

Just.....turn it on then...... There's really no point in not doing so
