Polling code is code that sits in a loop checking if something occurred. For example to deal with someone arriving at your front door you can do it a couple different ways:
1) Wait until you hear the doorbell then answer the door
2) Every 5 seconds you open the door to check if anyone is there.
Way number 2 would be an example of "polling code". It's not very efficient.
Way number 1 would be an example of "interrupt code". It's more efficient than polling in that case.

Thanks for the explanation. In this case can the issue be completely fixed or only reduced?
Not related to adaptative v-sync.. polling for clock maybe, but i dont think the driver will be in cause in this case.. ( dont it is made on the chip ? ). So maybe something as described by BriT.

this where a 120Hz LCD with vsync off will save your ass again 
. still pissed that there's no 120Hz non-3D IPS display.
there's at least one non-3D TN 120Hz monitor I've read about recently (no real reason it's not 3D except for not including the necessary hardware to sync with goggles)

I too thought this would more hardware based then software. Apparently that's not the case..

Btw, I couldn't get my hands on a 680, but I managed to order a 670 last night, so hopefully soon I'll get to see this first hand. Only real issue is that right now my display is a bit too small to really take advantage of the 670 (23" IPS), but eventually I plan on getting three 23" IPS displays, so that I might need to promote to 670 SLI to power them. I'm not going to do that just now, though, as I'm going to have to move within about a month and a half and I don't want to buy a whole bunch of big things just so that I have to move them.
23" is ok for a single... push AA, push quality... use SSAA when you can....
Lol i have use a long time CFX and SLI with 24" monitor.... just i push more the settings .. And i like to see the lower numbers framerate i can see is way uppon what my v-sync is .

just because your eyes can see up until 90 fps or so and because you don't get the 60Hz tearing crapfest.
I did play a bit of quake 3 and UT at 640x480 150Hz for fun, on crappy hardware, go back to your 60Hz LCD after that and you'll feel sorry.

Tearing is what triple buffering is for. The new adaptive syncing whatever thingy with the 600 series sounds like it could be cool, but it also sounds like it's a bit buggy at present. But I've been enabling triple buffering and vsync on all my games for ages. There's just no reason to live with tearing.
That said, technically there is still improvement up to infinity frames per second, because the frames are rendered discretely and higher framerate means more continuous motion. But in reality there are pretty severely diminishing returns above a stable 30fps, so that capping the framerate at 60fps is no huge loss. The main problems are stuttering and tearing, but triple buffering takes care of a lot of that, and does so generally better than just having a higher refresh monitor.
Well, I'll probably go ahead and get the two other 23" IPS displays once I get my new apartment. I really really doubt I'm ever going to be satisfied with a 23" monitor at home now that I have a 30" display for my office computer.

Is this sarcasm?
Oh, no, don't begin with this myth and following discussion about it.
Human eyes can distinguish frame rates of 90, 200 and 300-400 perfectly fine.

If you state such blatant BS it has to be started.
The average human eye thresold (in daylight) goes around 70-80 "frames" per second, ie after that the "images" get mixed together ("frames" and "images" as it's really constant flow of data in our eyes & brain, not single frames/images). The thresold also goes down the darker it is, and possibly somewhat higher in brighter light ('till a limit when it's too bright)
We can however see for example something that's there for less than that, like the famous "1/200th second image test for pilots", but the trick is that all the other 199/200 frames are blank - if all the 200 images shown in 1 second would be different, they would be just a big blur.
I see no good reason to get a "3d" monitor except for 120hz.
(so yeah, it was disappointing when the new 3d ips monitors turned out to be passive)

70-80 FPS is a ridiculously low number.
If so, would you be so kind to tell me why there is a very significant difference in smoothness when you play a given shooter with 80 and 280 FPS.
I will write it once again- if you give me two monitors, the first displays 80 FPS and the other one- 280 FPS- I will be able to tell you which is which.

Haa, there i will think like you... when you can use a bigger screen all days at office, going back to a small one is really hard.
Anyway, There's some good IPS 120hz ( 27" if i remember well ) you can find on import... Korean and asian brand.. ( problem is support if you have trouble anyway . ) They are incredibly cheap too.
