EXCLUSIVE: We measure G-SYNC Input Lag in GSYNC Preview #2!

You mean why it happens?

Do you mean why the lag happens at all? Or why it is 10fps below versus 1fps below?

Sorry, I should have worded it better. I understand the general theory behind what's happening, but I was indeed more interested in the threshold (1fps vs 10fps), but specifically what that threshold is quantitatively. I know I can cap my fps 10 below refresh rate and the lag appears to disappear, but I'm not sure if I'm eliminating all of it or if I'm underneath the threshold and I can push my cap further.

I'm no expert so, excuse me if this is a stupid question:

Was Battlefield 4 frame capped (internally) and would frame capping it under the monitor's refresh rate change these results? Battlefield 4/frostbite performance is pretty important to me, and I'm pretty picky about input.

Dont think that matters in the test because he was only getting framerate's in the 80's. So he should not have been getting any additional lag caused by hitting the 144hz refresh rate limit.

Soo after a while that G-Sync monitors are out.. is there any test of capping FPS and affect to G-Sync input lag ?
I would really like to know which fps cap is the best to lower latency of G-Sync in games that easily hit top fps..

Look here. 140fps most definitely increases input lag, but IMO 130-135fps is perfectly fine (i play with 135fps cap using G-Sync). There are no precise tests yet, and i also would like to know what is the limit for G-Sync, before it starts adding more and more input lag.

If you want to be safe set all your games max framerates to anywhere between 120-130. I can't imagine anyone would be able to see any difference between 120fps to 130fps whilst using g-sync. Can we get some opinions on this for those of you using g-sync. Try playing a game @ 120fps limited vs 130fps limited and let us know if you see or feel any difference. Thanks.
