Gsync not working properly

[Carsomyr]

Correct me if I'm wrong:

Gsync is different than vsync: It turns off vsync when you go below your refresh rate (say lower than 144fps which is my refresh rate 144hz) and it turns vsync on when you go above 144fps to prevent tearing correct?

Well I'm playing overwatch fullscreen with gsync enabled and I go well above 144fps. Shouldn't gsync prevent this?

Not quite. Just Google for how it works. I'm on my smartphone now, so can't give a comprehensive answer.

If it goes above the refresh rate then it's not enabled , G-sync allows the monitor to display an image every time the GPU is ready to send that image without a fixed synchronization. But you are still limited by the refresh rate obviously.

It seems to me either V-sync is off in your case or you're using Fast-sync.

With Overwatch [on a g-sync monitor], I've had the best result with V-sync Off and a frame limit set a few fps below the refresh rate of the monitor. For example I've got a 163fps limit set and my monitor can go to 165hz.

its fast sync

 

[Carsomyr]

Fast sync is set to off. gsync is on.
in game vsync is off.

so what you guys are saying is that the FPS behaviour is normal then?
If I'd want the FPS to stay below the refresh rate of my monitor I'd have to either:

1. Turn on V-sync on top of Gsync
2. Cap my FPS to something just a bit below my refresh rate
3. or use fast sync? Does fast sync combine well enough with gsync?

Lastly and most importantly. Could you give me a rundown of which "syncs" are best for these scenarios:

1. For games which typically run around the 200-300 fps mark because they're not taxing my system (FPS games for instance) What combo of Vsync/Gsync/Fast Sync should I use?
2. For games which are very taxing such as The Witcher 3 where my FPS would mostly stay below my refresh rate all the time?

download nvidia inspector... and limit your fps.

1. Fast Sync, because it introduces no tearing / latency when running over your monitors refresh rate.
2. Gsync will solve that. That's the entire sense of Gsync, unless you go under refresh rate supported by Gsync, but then you have other problems anyway.

Again: Gsync syncs your monitors refresh rate to your FPS to prevent tearing etc, so "2." is practically impossible unless you go under supported refresh rate of Gsync / your monitor. In other words: your refresh rate = the FPS you would have in that game.

so for scenario #1 I'd be looking at fast sync: What does Fast Sync do? Does it lock the frame rate to my refresh rate when the FPS wants to go higher than refresh rate?

Gsync does not limit your framerate by its own. I have mine setup like this (100hz monitor frame limited to 95fps through afterburner)

Works as expected.
