Nvidia Fast Sync with GSYNC

[AngeleJR]

As to my understanding, regular VSYNC will only turn on once the frame rate goes above the monitors refresh rate when using a GSYNC monitor. Ever since Nvdia's Fast Sync came out, I've been debating whether to start using that as a default or not. What do you guys think?

Vsync works at all refresh rates, what it does is it won't allow for a new frame to be rendered until the monitor has its next refresh.

 

Fast sync will let the GPU render what it will and then it will introduce the newest frame with the next screen refresh, so for example if the GPU renders 3 frames before your monitor is ready, it will send the monitor the newest frame, unlike vsync where it will send the earliest frame. (its the same a vsync essentially, but with less noticeable input lag)

 

If you have a gsync monitor what you want to do is limit the FPS to the top of your gsync limit. I use rivatuner (it comes with MSI afterburner and has minimal impact compared to other methods.) You can also use vsync or fastsync to limit the fps, but I find its not as smooth as if I just limit the FPS using rivatuner.

I have been doing this wrong this whole time then. So I would have to just limit the FPS instead of using VSYNC?

Fast Sync has a terrible micro-stuttering in my opinion, I would stick to V-Sync for sure.

 

I'm still debating if I should use V-Sync or Adaptive-Sync with G-Sync, maybe someone that has a G-Sync monitor can help me out. Does micro-stuttering happens with Adaptive-Sync + G-Sync, when FPS bellow 60?

There is tiny micro-stuttering with any game that I've played when you have an SLI system, which I do. When your game reaches below 60 FPS, say around 40, the game is still very smooth. The downside is there is increased input lag. You can feel the input lag very drastically. What I have done is downloaded Nvidia Inspector and cap the FPS accordingly and turn off VSYNC in any options that you see. Granted you still see the micro stuttering, but you'll get less of the input lag.
