Maybe for about less than a second, you might have that happen, but in the real world, that isn't happening for a severely extended period of time.
Those exact same users were saying there is no micro-stuttering at all. As someone who had used two 7970s, the difference between 13.8 and previous drivers was utter night and day. I'm extremely susceptible to seeing it. Maybe you or others aren't, but that doesn't mean it didn't exist. Because it did. To claim it didn't exist would be foolish.
And yeah, a great majority of the time, you end up getting used to those problems, and it becomes a non-issue. That does not mean it doesn't exist. It means you overlooked it. Especially with something like V-Sync input lag. You are going to have it no matter what. You might get used to it, but it is there, regardless of how you try to overlook or mitigate it.
Its really dumb seeing people consistently denying a major problem exists. Tech doesn't advance on denial of issues. It advances on people seeing a problem actually exists, and do something to rectify it.
On point one: I already said 0
tearing at all with DFC set to 75, but at 60 I did get some. So apparently it can be tweaked out, at least to the point of being unnoticeable if it still exists.
On point 2: I am not denying the existence but that with proper tweaking a lot of the issues that people like to speak of can be remedied. See above.
On Vsync input lag there is a lot of debate on its actual effect. I guess it depends highly on the buffer and frame rate. It is kind of like those people that claim that they can see the diff in 120 and 60hz monitors. I have no doubt they feel the difference but I doubt they see it. There was a study with a red 10ms light followed directly with a green 10ms light (I think I have the colors right) everyone, all , every single person SAW A YELLOW 20MS LIGHT. So to put that in perspective 60hz = 16.67ms 120hz = 8.34ms so two frames of 120hz is likely indiscernible from the 60hz single frame. You can feel the difference for sure and that is likely what people akin to smoother gameplay. Now going back to the 10ms lights, the red light and the green light did exist, that is fact. But what was seen was yellow which in a way exists but is not fact or actually what was rendered.
Ok back to the tearing and stutter: Based on the 10ms lighting, users may and obviously a number have managed to overcome and alleviate the factual problem that exists due to the nature of GPU, game engine and monitor operation. That fact in no way claims the problem doesn't exist. That same argument of 10ms light applies well enough to input lag as well. I have seen lag estimated to be about 23ms, probably an avg. 23 ms is likely indiscernible to a great degree. I think it can be noticed but I don't see the huge issue here. Besides it is the buffer that institutes the lag not Vsync it self. Lowering the buffer or any prerendering of frames has a huige impact on that lag measurement.
Any way I think this is where the problem is, communication. For those, myself included, that manage to eradicate the problems with some indepth tweaking, we fail to see the value in things like Gsync, I mean as an item with cost and its worth to us. Doesn't mean we don't think the tech has merit, just it does little to sway us to consider the purchase of said products. Then there are those that have the issue and have yet to get the same results as us that deem us as liers or naysayers. I have tried to bridge that gap and explain how one may not see the value in Gsync and it is continually met with harsh debate to the point of questioning my integrity and honor. All I ask is just try and have an open mind and read what both sides are trying to say and how those points are based on their experience. All the tech in the world or facts of science will never speak to true human experience.
