the C1 is one of the best for sure, (that was my other choice)

just pointing out that the Samsung QN90A is also a unit to consider with excellent brightness, colour volume, great HDR experience & with no image burn-in problem,

all this gives a wonderful VRR experience with MFS today…

I've got the Samsung QN70A 65inch and can attest to all that also.  Although I am limited at the moment so far as VRR is concerned  because I have no suitable cable to connect the GPU and Display just an old HDMI 2.0. But I'm getting there!! Its a beautiful screen to fly with!  

How have you configured your VRR Craig? Did you select Adaptive Sync in the NCP? Are you using a Display Port cable from your GPU to Game HDMI on your display or are you using HDMI 2.1 cable from the GPU to Game HDMI?

And that was my second choice - amazing panel too! Still a tad more expensive than the LG at the moment, but that should equalize over the next little while.

QN90A connected from 2080Ti via HDMI 2.0 Premium Speed cable (18Gbps certified) which allows 4K HDR at 60Hz,

XboxSX will be connected at full HDMI 2.1 (48Gbps),

just put the QN90A in Game Mode with VRR enabled,

& just use the NCP frame limiter to suit - have settled on 40fps for the moment…

also, in NCP Global the Monitor Technology is set to G-SYNC Compatible & Vertical sync is Use the 3D application setting,

in MFS not using VSync - it is off - NCP frame limiter works better on my system…

(& the frame limiter stops the 2080Ti from being 100% hammered by MFS)

You want the gpu 100% used by MSFS. That’s the whole point. Actually, when the gpu is at 100%, it can stop you being main thread limited and eliminate any last stutters.

Anynone with g-sync, I would recommend locking frames at 60. If it drops below, then G-sync will just kick in anyways and smooth it all out. So, you could be variable between 30-60fps. And not really notice.

Unfortunately, freesync isn't available on the 43" version of the QN90A ☹️

Following this thread with interest, I have just added an RTX3080 coupled with I7 10700k processor and have a Gsync hardware monitor @ 60hz although it can go up to 240Hz
 

im a bit confused with where to fix at 60fps, NCP or in sim with sync ?

at the moment the sim is very smooth with the odd little stutter, averaging 40-50fps in heavy scenery in the FBW A320 sometimes up to 60fps limit which I’m guessing is because the monitor is set to 60Hz ?

any advice is welcome as there seem to be so many options

cheers

From my understanding of how Gsync works you shouldn't need to 'fix' it any any frame rate because that is what Gsync does--it syncs variably with whatever the unrestrained frame rate can be, else what good is it?  Someone more knowledgeble will chime in and set me straight on this as needed 🙃.

Be aware if you aren't already there are other known sources of those 'odd little stutters' including when the small snake chasing its tail indicator appears on the lower right part of your display, and also sometimes when ATC executes a line of speech.  The former can be solved by toggling Dev Mode on and off, save and resume your flight, and the latter by the so-called 'ATC Stuttering Fix',. a modification which limits the lines of ATC to only 4 and somehow by magic this essentially eliminate that source of stutter.    I have LOD set higher than the sliders go by editing UserCfg.opt file, and on occasion that will exceed what my configuration can handle and an odd little stutter may happen, but most often that's not the case--when it does happen I just open up Options and set LOD back to 200 (instead of 300/400 from the file edit).

And neither is 120hz or VRR support apparently - Samsung really handcuffed the panel in this size.

You need to cap the frames in the nvidia control panel, never in game. Cap them at 3 frames below your monitors maximum refresh rate. So if your refresh rate is 120hz, cap them at 117. This stops tearing if you exceed 120fps. 
Of course this isn’t happening in MSFS. I recommend capping at 60fps, because that’s a good target to aim for in MsFS, plus it gets rid of the gpu hammering itself when the MSFS loading screen is on. 
 

On another note, if you want better frame pacing, I would cap not using nvidia control panel, but by using MSI RTSS. I cap the game to 60FPS using that method. 
 

pps, if you have a 240hz G-Sync display, why do you have it running at only 60hz?! Let the thing run at 240hz, and then when you’re in MSFS, with G-Sync enabled and the cap of 60 set in RTSS, you should be good to go at the highest level!

Thanks for the replies
my times a bit limited at the moment so grabbing quick sessions when I can and have been messing with with different settings in a not very methodical or logical way hence the monitor being at 60Hz

off to try your recommended settings Ian

i’ll let you know how it goes

Best

So after a couple of hours tooling around in the FBW a320 at all altitudes around Bristol with Pilot Plus add on I can say it’s running silky smooth with Ian’s recommended settings, monitor @ 240Hz, simulator limited to 57fps in NCP, Vsync off in the FS2020

ok there is the occasional small random stutter but too infrequent to ruin the illusion of flight, the annoying micro stutters have vanished, especially those on the ground out of the side windows when taxying/ take off

now looking into RTSS

I’m glad you listened to the advice, it makes me happy because if more simmers invested (if they have the means to) in g-sync, then we can kiss goodbye to 30fps locked forever. 

[bean_sprout]

Never locked at any fps in any sim.  No point really.

Well there is.  As Ian explained.  I have a 3080Ti but will still cap it at 60Hz / fps, because that is enough and why have all the extra heat / noise / and power consumption when you don't need to.

Then of course there is the stupid way it tries to run your GPU flat out during updates.  

I have found RTSS is the best way to cap / lock your frame rate with the Nvidia card.  Works brilliantly. 
I actually cap it at 10 fps during updates, as it takes seconds to turn it back up.

I have been fortunate enough to test this numerous times, as I have a Ultragear G-Sync hardware based monitor and also a G-Sync compatible based LG C1 TV. 

Well we have all covered a lot of ground with V-Sync, G-Sync, Free-Sync, capping FPS and VRR. In an earlier post I mentioned HDMI 2.1 and you will see that @craigeaglefire is incorporating that into his Samsung QN90A when he gets his XBox rig.  I have also mentioned doing something similar with my Samsung QN70A 65inch Display and RTX 3060 and hope to get my hands on a certified HDMI 2.1 cable tomorrow. I really was thinking that this is just a way to get Free-Sync to work although I might have some configurations issues running it from an Nvidia GPU. But looking at my NCP it doesn't look like I have G-Sync or a G-Sync Compatible option so it's a good thing I didn't splash out for G-sync capable display but also a bit sad that I may now not get much benefit from my Free-Sync display. But then I saw the article below about HDMI 2.1 or more specifically HDMI VRR.  " HDMI 2.1: Why It Matters for PCs and TVs in 2021". The salient point from that article is where it discusses how HDMI VRR prevents screen tearing and then says...." PC gamers might sense a parallel between HDMI VRR and the existing Nvidia G-Sync and AMD FreeSync technologies, which serve a similar purpose. Like them, HDMI VRR is its own standard. All three technologies require both the source and the display or TV to support them." 

So in 2021 I'm sensing we have a not much hailed about capability of HDMI VRR to achieve the same as G-Sync and Free Sync but without the especially expensive costs of G-Sync capable equipment.

Given your experience and knowledge @Ianrivaldosmith with G-Sync I'd be interested in your thoughts Ian on HDMI VRR and whether you would see it as achieving the same as G-Sync or whether it is more just another one in the line of G-Sync compatible approaches to the problem that perhaps do the job but not as well as G-Sync?

With MSFS most of us are not too concerned about really high FPS because we know we can't get that. But between kicking the tyres and lighting the fires, and engine shutdown, we just want as smooth and as fluid a flight as we can and VRR in any form gives us a chance at that.  It just seems to me that HDMI VRR maybe another useful tool in our box and more so because unlike G-Sync and Free- Sync, it seems a little more universal in that so long as you are 2.1 at both GPU and Display, (which it seems both card and display manufacturers are quickly coming on board with), then it matters little what brands you might be mixing together.
