If average FPS is below the monitors refresh rate, and assuming no frame generation is being used, is it generally better to have Vsync on or off?
For example, a typical FPS in the 45 to 55 range with a 60Hz monitor.

Thanks,

With your 60 Hz monitor, having Vsync on would cap your FPS at 60, but this is fine since your average frame rate is in the 45 to 55 range anyway. The main advantage of having vsync on in this scenario is to eliminate the irritating tearing of your display, particularly when panning around your cockpit or your external view. Well worth it in my opinion.

Vsync won't fully eliminate tearing if your frame rate doesn't hit your monitor's refresh rate. In that case you should enable G-Sync or Freesync if your monitor supports those, which it probably doesn't.

Thank's Alvega and rlashier for the info.
So if Vsync is to be on, is it best to turn it on with the sim setting, or through Nvidia, such as by the Nvidia control panel or app, or it doesn't make any difference?

And while I'm asking questions, what is the Vsync recommendation if you use some form of frame generation?
Or maybe stated another way, when is it best to not have Vsync on?

I appreciate the help,

Al the best is to use what works best on your machine.  

I have a RTX 4080 and use frame generation - for me I've had good results with just setting max frame rate to 143 (1 less than my 144hz monitor) via Nvidia Control Panel but I've also had decent results with locking it in sim to half my monitor's refresh rate 

Some people recently are saying to just do that IN SIM and tick the "dynamic fps target" option (assuming we're talking 2024 here - sure would be nice to have a separate forum so we could tell what sim people are talking about since they are so different).

But note if you do tick the dynamic settings option it really reduces the scenery loading range...it's pretty noticeable (in a bad way) but yields extremely smooth gameplay.

Ryan, you've honed in on exactly what I am trying to get a better understanding of. I might have to test NCP vs In-Sim FPS target setting and see what happens. V-Sync and the Dynamic FPS target options are greyed out if you use DLSS.

As you have a nVidia GPU, does your monitor support GSync? If it doesn't, you should budget for an upgrade to a monitor that supports a variable refresh rate (VRR) as it will really make a difference to smoothness. VSync is old tech and should only be used on displays that have a fixed refresh rate.

I'm using a OLED, and they DONT like fluctuating FPS! In the dark you can clearly se flicker.
The best FPS lock is the monitor limit, so I set it for 60 FPS, which will keep me a steady sim - resolution and refreshrate in nVidia panel.
BUT, when using framegen, there is no vsync option in the sim.
So I lock the vsync external, and can keep my perfect 60 FPS lock with no tearing.

I tried the FPS limiter.
But it is NOT as perfect as a limit by the monitor.

I have an OLED HDR display on my wish list, are you saying they don't like a variable refresh rate?

When I used the full scale, not much on my "monitor" - 120hz - 4k
And the FPS was fluctuating.
In dark areas, the screen would flicker or something like that, EVERYTIME the FPS changed.
I don't know if this has become better on newer Tv's I'm on LG C2.
But the FPS hard lock fixes it.
And this is not just in MSFS, it happens in all other games/software.

You can try google it a bit, it sure is a problem.

When that is said, the color and black is SO good.

I wasn't aware of this, thanks for the heads up!

What MrBitsFlyer asked is important. Which sim do you use ?

If its 2024 :

- Set framerate inside 2024 to 30

- Use FG (hardware based) or FSR ( software based )

I use both sims these days.

OK, then under Dynamic Settings I assume I set Frame Rate Target to 60 -- correct? 
I should have mentioned I'm using a 4070Ti Super, Win11 and a 42" Samsung TV with both sims.
