What is the difference between Adaptive V Sync and Vsync? (Doom)

[Boss Big]

I saw both of them in the game. Which one is better?

I have a 60 fps monitor unlocked to 80 fps and I also set the game to 80 fps by RivaStatic Tuner Server.

In this case what about Vsync?

Firstly the difference between adaptive and non Vsync is that regular Vsync locks the refresh rate to your monitors hz WHILE ABOVE THE MAXIMUM HZ, while adaptive vsync does the same except when it goes even one frame below 60 (or your monitors refresh rate), it will half the FPS so you won't get screen tearing. About the FPS limiter, it's doing almost no good capping it at 80 if your refresh is 60hz, so either set it to 60 FPS or just take it off and use standalone v-sync, which ever you like better.

Not quite. Adaptive V-sync turns v-sync off when you drop below your refresh rate. Regular V-sync, when using a double buffer system, is the one which often drops to half FPS, not because it's a rule of regular v-sync, but just what happens as a result of not letting the GPU to work on a new frame until the finished one is displayed.

Anyway, V-sync and adaptive V-sync stops tearing and locks your FPS to no more than your refresh rate.
Adaptive V-sync turns V-sync off if you fail to reach your refresh rate, so tearing will occur at that point.
V-sync will not allow tearing regardless of FPS, but can result in much lower FPS, often half FPS if you are not able to reach your refresh rate in FPS (this happens with double buffering, triple buffering fixes this, but can result in stutter).
Adaptive V-sync has an option to lock FPS to half your refresh rate.

Why not?
I have a gtx 1070 and get more then 110 fps in most games, thats why I thought it would be best if I overclock my monitor to 80 hz and use RivaStatic to lock the game to 80 as well so there won't be screen tearing.

I think you're on the right track if you're careful to lock your framerate to your refresh rate, no matter what the refresh rate is, as long as your framerate is ALWAYS above that number. So if you never experience a framerate lower than 80fps, locking it to 80fps is fine.

 

[MnMWizard]

Oh I misunderstood what you said, you meant you overclocked it to 80hz, then ya cap it at 80 FPS if you don't like the v-sync input lag. If you haven't already, test your monitor overclock and see if you're getting frameskipping: https://www.testufo.com/#test=frameskipping

I only read about the input lag in vsync recently. If I lock it with Riva and turn off Vsync can I get rid of the input lag?

 

[MnMWizard]

Yes it should, I personally can't tell a difference in input lag, but I'm sure some people are more tuned to it.

Isn't screen tearing happens if the fps is higher then my monitors refresh rate?
That's the reason I should lock it on the same fps as my monitor's refresh rate which is 80Hz in my case.

 

[MnMWizard]

Yes but v-sync does that as well, and some people like v-sync, some like a frame limiter.

 

[Boss Big]

So what I am doing is the frame limiter solution, yes?

What's the downside of this method? Or should I use Vsync? I tested Doom with Vsync on and off, but if RivaStatic is installed Fraps said the game always run at 75 fps, no matter what I did with the Vsync ingame setting.

Tearing has nothing to do with your FPS. It has to do with syncing the frame's delivery with the monitor's vertical blanking mode. Simply put, tearing occurs any time you do not use some for of syncing solution. Frame caps do not remove tearing. They do not sync your frames delivery with the monitor, even if the refresh rate and FPS are the same. In fact, it is often much worse, because the tear will move very slowly, making it super easy to see.

So, that means what I am doing with RvaStatic Tuner isn't a good solution either?

As I mentioned OCd my monitor and run every game on 80fps lock with this program, the Hz and the fps is the same.

But I should use 60 fps Vsync instead?

Is there a way to "use" 80Hz Vsync?

I know there are some G-sync monitor as well, but they are way too expensive for me.

V-sync doesn't lock you to 60hz unless you have a 60hz monitor. It locks you to your refresh rate. If you have a 60hz monitor, then it's 60 FPS, if you have a 120hz monitor, it's 120 FPS. If Doom is locking you to 60 FPS, then the game has put your monitor in 60hz mode (some games may do this).
