"If you're still debating between G-Sync and FreeSync, here's what we've observed so far. G-Sync has the advantage when the action drops below 40fps for sure. At that point, frame-doubling takes over so there is no tearing even when stutter becomes a problem. FreeSync is supposed to switch to V-Sync mode at that point but in some instances, we've seen that this does not happen. Then you get tearing and stuttering, which makes gameplay much more frustrating.
However, if you can keep the refresh rate above 40Hz, there is no difference. Concerning the fact that overdrive is currently disabled in some FreeSync applications we can only maintain that in the vast majority of games, it is not a limitation. Even right above the zone, when frame rates are in the low forties, we can't see ghosting. And when playing at a comfortable 60fps or above, motion is super-smooth and tear-free.
The bottom line is right now you can go with either tech and come out happy."
Yea, there is a difference. Over about 65 fps, most will want to turn off G-Sync and use ULMB which is hardware based. Freesysnc is "free" only because it does not come with the necessary hardware to do ULMB. Some manufacturers will provide it on their own but the result is of varying quality since, unlike w/ G-Syn, there is no standard.
As to some of the other comments ....
Ghosting and IPS "Glow" are reasons why I would never recommend a IPS monitor for gaming, until now .... searching for the faintest light on dark unlit areas of a game would drive us crazy on the Dell IPS panel. However, the combination of G-Sync, 144 Hz and ULMB solve the ghosting issue and the quality of the panel is such that the IPS Glow, if it's there, it's not noticeable.
As for the it would be good if it was 1ms comment .... Yes, many people advertise 1 ms but it's not real. Here's how the top monitors measure up in the laboratory using results of actual testing. However the impact of response time musty be considered along with signal processing in order to measure lag .... The BenQ2730Z example has a best ever 1.7ms response time but it's combines time with signal processing is 4.0 ... the Predator's combined time is 3.0 , What a manufacturer puts on his advertising is meaningless, it's what shows up in the lab that counts.
