Anyone any documentation for this feature just added? Does it need Vsync on or off? Frames capped or not? Looks like it could be handy for my G-Sync if I can figure out how its working...

 

 

Vsync on with capped frame. Because if you reach your monitors refresh rate you won't get the advantage of gsync, It'll be just vsync. And you need vsync on for smoothness.

General rule is 2 fps below monitor refresh rate for frame cap.

It's explained perfectly here,

He's asking about it in relation to the newly added VRR option, not generally. I am also curious what that tickbox does, as I haven't seen one for VRR in any piece of software. 

My bad, VRR was added to Windows for UWP games. I wonder what it does for p3d. Sorry about unrelated post.

Actually this is how it works in P3D

However, I am curious as we say what the new VRR option brings to P3Dv5....

I think maybe @Rob_Ainscough is going to make a video about G-Sync and v5. I made a similar thread in the official forums. I’m eager to understand what’s different about this VRR setting.

I saw someone recommend turning vsync on to improve performance a while back.  I tried it, and lost a bunch of fps.  Vsync OFF works best on my system in P3D.

I'm convinced there's no "magic bullet", no "one-size-fits-all" settings that can universally optimize performance - just way too many variables, and also variables that interact with each other.  No way to just say "Do this and it'll work".  Not that simple in most cases.

V-sync is largely irrelevant if using G-sync (unless you go over your monitors refresh rate of 100hz+, which is not going to happen in P3D very often if at all!) 

 

I have been doing some testing, V-Sync off and capping frames at 97 (3 below my monitors max refresh rate) with the new VRR setting on, and it does seem a lot lot smoother! I will keep testing...

"Monitor refresh rate of 100hz"...LOL.  My Samsung 4K monitors can't do that, but it's unimportant, since anything above 15fps or so looks "smooth" enough for me to enjoy the experience.

And YES, forumites, those one or two of you who became apoplectic a few days ago when I posted that I can even tolerate as low as 12...that would be 12...fps, and still fly.  😄  Do I like it?  No, of course not, and I do everything I can to get it higher.  With v5, it's not that difficult to do.

The thing is, I use P3D's Viewgroups to spread P3D across three 4K monitors, and that's moving a HUGE amount of pixels.  I set my FPS limit in P3D at 30, and in flyover country, I get that.  High density areas, New York, Houston..etc, it drops to 25 or so, but hey, big whoop - still very much flyable.  And having the scenery spread across these three monitors is VASTLY more immersive than having to view the world outside through the peep-hole of just one, no matter how large that "one" might be.  Note that this is with Viewgroups, not just stretching the view over 3 monitors.  Big difference - cockpit instruments stay round.

But, Vsync?  Nope - doesn't improve anything for me.  And I've also tried Samsung's "Freesync", which is their G-sync clone, and I've found that THAT doesn't improve anything either.  So for me, no Vsync, and no Freesync...and it's optimal that way FOR ME.  YMMV

Yes but it still doesn't answer the main question of this thread, the new VRR setting.

Also, FPS isn't everything, smoothness is.....

Not sure about p3d since I can barely go above 30 fps anyway, the reason vsync is recommend is because without it, you can experience screen tearing below 2-3 hz below refresh rate.

Not with G-Sync, thats the whole point of the thing....!

Absolutely correct.  But anyone with some experience simming knows that smoothness and fps are directly related.  Let frame rate drop below some nominal level, and it's a slide show.  "Smoothness" is gone at that point.

IMO, the main question of the thread, the VRR option, should easily be answered with a little experimentation.

Not really. I can easily get 70fps with P3D and it’s not smooth. I can drop down to 40 in another scenario and it is smooth. 
 

seems to me the modern engine can’t load the scenery quick enough and it stutters it. Like trying to shove too much down the sink at once. 

PS. If they’re gonna put in a new feature like this, I’d be Inclined to say they could at least explain how it works etc... some documentation would be nice.
