Nvidia's vsync vs AMD's vertical refresh

[sheepsnowadays]

Can someone explain the difference between Nvidia's vsync and AMD's vertical refresh? Why do people boast about Nvidia's vsync?

 

[sheepsnowadays]

Nvidia developed a technology called adaptive vsync, which keeps your framerate from needlessly dropping in games when your PC can't generate a framerate as high as your monitor's refreshrate, while also getting rid of screen tearing.

So for example, on standard vsync your PC might be capable of outputting 55 fps but if your monitor is 60 Hz, you're only going to be getting like 30, 40, or 45.

I don't really understand how the tech works, but that's the effect.

You have AMD cards i was going to ask you if you noticed what you described with vertical refresh only getting 30 or 45 when going under 60 (i havn't) but i doubt you get less than 60 fps.

Basically the reason why people boast about adaptive is because when you reach 60 the software turns on but when you go below it turns back off it as its names suggests adapts to your situation in a game. Vertical refresh to my knowledge only controls when vsync is turned on.

Thats pretty much exactly what i told him in the last thread he asked about it... Eh oh well.

Has anyone with an AMD card verified this? When i game with fraps my card seems to behave just how you describe Nvidia's adaptive vsync and wondering if it is just marketing

Adaptive Vsync is marketing plain and simple, with it on or off I do not notice any differences.

It is a very hard thing to watch unless you are doing something that is constantly pushing beyond the 60 FPS barrier if you have your settings pushing you below that margin or around it I would think you wouldn't notice it. With older games I'm sure it would show quite a bit.

turning Vsync off is a better option anyway

 

[bigshootr8]

Right I would only turn it on if you were to experience tearing in a game. Which then I would use adaptive. I don't think its a marketing gimmick. I just feel that for most people they won't need it if they are properly adjusting there in game settings to what they ought to be set at.

 

[paulemannsen]

adaptive will only turn vsync on when you hit or are above your monitors refresh rate. its doing what i already suggested to you doing manually in the other thread. just read the wiki article about vsync.

 

[paulemannsen]

exactly. it doesnt prevent tearing at sub refresh rate of the monitor. thats logically impossible without losing some frames.
im not sure if you can specify a limit where vsync turns on, like at 40 or 80 fps or so. maybe a nvidia user can verify this?
still, it makes the most sense to adapt it to your monitors Hz.

 

[bigshootr8]

Its less violent then vsync because instead of doing 2 actions with normal vsync adaptive does one. It does help with tearing because it keeps your frames at 60 fps and only turns on when you get above 60 fps instead of locking you in at 60 fps. It's a smarter vsync.

vsync = unstoppable ahahaha!

I think it was a pun against your card as I did a google search and couldn't find a single one. The Twin Frozr cards have excellent coolers anyway if you wanted to overclock with water probably could just get a ASUS TOP card which probably uses a 680 PCB and be good to go.

:lol: pun these nutts my cards are fine.
