Frame Capping and G-Sync

[InfamousGeezer]

From what I understand about G-Sync it will match the frame rate of my GPU. However if I was to use RivaTuner to cap my frame rate does this hinder G-Sync?

Here's an example of what I'm currently doing. I am playing Doom and when V-Sync is off within the game. The max fps is 200fps. My monitors refresh rate is 165hz when overclocked. I don't want my GPU & CPU trying to push out frames it can't display so I'm choosing to cap the frame rate with RivaTuner to 165hz. Here's what's bothering me. Does using RivaTuner have the same effect as running V-Sync? Does it have the same problems that V-Sync has such as stutters and input lag? What's the best way to cap frame rate without any penalties using G-Sync?

if you have gsync on your monitor, use it. else just continue using rivatuner. don't use vsync/rivatuner if you have gsync.

The thing is when G-Sync is enabled.  Dooms fps is saying that it's running at 200 fps and my GPU can only handle 165hz stable.  What annoys me about G-Sync is that unlike V-Sync.  V-Sync will know exactly what your max refresh rate is and lock it to your monitors max refresh rate but with the problem of input lag.  I wish that G-Sync knew what your monitors max refresh rate is like V-Sync does.

i just keep it at the highest fps my system can do, i dont really notice screen tearing but i do notice the input lag between 60 and 120fps in something like minecraft

I guess what I'm trying to say is that I like my framerate to be as stable as possible.  So I want my GPU to run at 165hz ALL the time.  I don't want it dropping below it or going above 165hz.  Why?  If I was playing a shooter like CS:GO and my fps is going up and down all the time.  Does that not mean that my aiming is off because the refresh rate is changing all the time?  No consistency.

how i see is, if you want your framerate to always be or be above the monitors refresh rate (as in, always 165 fps or more), then you should just uncap it .. or cap it at 2x165 (330 fps)

in csgo, you dont ever want to cap your framerate. less smooth and you're missing maybe 0.5ms of information every frame

 

your aiming isnt off because the refresh rate is changing all the time.. its off because you were off already, and if you micro adjust it then you'll get like a 0.5ms advantage seeing it a split frame earlier be aimed

G-Sync only operates below the monitor's refresh rate. If your framerate is equal to or above the monitor's refresh rate, then G-Sync does not apply at all. You can choose in that situation to either switch to V-Sync (which will cap your framerate) or do nothing (which will allow your framerate to be anything, as normal when you have neither G-Sync or V-Sync active). You can also cap your framerate either with Rivatuner or with the CS:GO console, people debate about how much lag each one adds, you can just test it yourself though. And if you can't tell the difference, then surely it doesn't matter?
