Tearing.

okay thanks that's what I thought. I was just making sure I understood this correctly.

Yeah, at the same framerate within the refresh rate, G-SYNC + V-SYNC off and standalone V-SYNC off have up to 1/2 frame (so anywhere from 0 to 1/2 frame) advantage in input lag at any given point when compared to G-SYNC + V-SYNC on. This is exhibited as tearing; whenever you see the tear, you're seeing you're literal (and only) input lag reduction over G-SYNC + V-SYNC on.

wait what do you mean by gsync+vsync off and standalone vsync off

- G-SYNC + V-SYNC on = G-SYNC ON + V-SYNC ON
- G-SYNC + V-SYNC off = G-SYNC ON + V-SYNC OFF
- standalone V-SYNC off = G-SYNC OFF + V-SYNC OFF

so gsync+vsync off's advantages over both on is only less input lag?

Tearing. When you're asking for less input lag in this case, you're asking for tearing. There is no other difference but that between G-SYNC on + V-SYNC off and G-SYNC on + V-SYNC on inside the refresh rate.

but you said gsync+vsync off has an advantage in input lag over gsync+vsync on

The input lag advantage is TEARING



G-SYNC + V-SYNC is the fastest a single frame can be displayed tear-free; for any faster delivery, it has to tear (aka G-SYNC on + V-SYNC off or G-SYNC off + V-SYNC off). That is your only input lag "advantage" over G-SYNC + V-SYNC: tearing.
