Good monitor reviews include a test of the delay. 3 frames delay (<100 ms at 60hz) is absolutely atrocious and easily detected by players in games.

But of course, that's not the problem. It's ok that the phone doesn't unlock with out me noticing the delay. It just can't be so long that I start doubting whether it works.

I notice a 1 frame in 60hz delay (<17ms) when comparing vsync on vs. gsync @ 57 fps. I'm sure many other video gamers will as well.
