Interesting - my smoothest setting so far is the monitor at 120Hz with the Frames set at 20, so 40fps in sim.  I have G-sync and Vsync turned on.

Doing this disables g-sync. and the reason you get 40FPS is because 40 is a third of your motors refresh rate of 120hz. 

Actually, it's pretty smooth this way too. You should also try it with vsync disabled, and g-sync enabled, and lock the frames using RTSS to 40 or 50 or so, and it should be smooth too.

 

PS Only if you have a proper (Hardware based) G-sync monitor. If you have a compatible one, I wold stick with Vsync on 20.

Enjoy the new rig. It also depends on what screen size and resolution you are running at...

BTW, if you want to squeeze out more performance, here are a couple more resources:

[MSFS] How to get a SMOOTH experience in Microsoft Flight Simulator 2020 - YouTube

 

Really helpful, abit humbling that a 5800x+3080 needs to run @30FPS to get a smooth experience but thats on asobo....  After locking to 30FPS w vsynch no more stutters and very smooth. Sim looks great still so cant complain too much but dreams of a smooth 60FPS on the ground is VERY out of reach w the way this game is optimized.

I'm running the 5800X+3080FE combo with a 3440x1440res monitor and set my sync to 60fps. Very smooth with all settings on Ultra.

I personally would never disable g-sync. It's a dream come true for me. Ever since I got my official g-sync monitor performance has been butter smooth with settings at ultra. In fact, performance is so smooth (BTW I seriously have no clue what fps I am getting) that I might change the render scale a bit and see what that does to my already awesome graphics! Seeing all that detail down there pass be without a single stutter really is incredible. Never ever experienced such smooth performance in FSX/P3D/XP before!

I found switching to 60 hz and capping framerates at 30 fps

Have you tried 120hz and then set vsync to 20 in the sim?

This will lock your fps to 40, quite smooth and way better then 30fps, this is how I have it setup and I love the smoothness.

The thing I found increasing render scaling did for me Glenn is that it reduced a twinkling effect around built up areas, a bit like increasing antialiasing.  It does come with a huge performance impact though, so I've had to scale back to 100, though that does give me a little more headroom to increase LOD a little.

I may have to scale back a bit when I use more complex aircraft/scenery though.

For the TS with his brand new CPU, I guess he wont run into much CPU limitation using 1440p with a 3070. However, to fine balance things, render scale slider could still be valuable as well. 

Exactly what you guys are saying…trying to find the balance of these two, and where it’s more effective, or just plain looks better while keeping as much performance as possible. 
 

Cianpars, totally agree with your take on render scale, it’s like turbo antialiasing and looks fantastic even at 110. Less shimmering and just sharper overall. I’d like to increase it, but as you say, there’s a decent performance cost. I’ve seen several people at 130, but I’m guessing that’s for the beefier cards, 3080/3090 or equivalent.

Sorry, what disables G=Sync?

With my 2080ti at 3440x1440, I find I can't go above a render scale of 100 plus a decent level of detail without the performance suffering.  I have set my resolution at 2560x1440 @ 120Hz, render scale at 120 detail at 320.  With these settings I get amazingly smooth performance at a steady 40fps (frames set at 20, so that's 40fps)

When you activate V-Sync option within MSFS itself, it disables G-Sync.

Yes me. I have 100hz gsync UW monitor. If I turn vsync in game on, gsync is disabled.

I have in build fps counter in my monitor. When gsync is working, it shows fps. When gsync is disabled, it stays at 100 (or whatever refresh rate is set) So, if I turn on vsync in sim it shows 100. With vsync off it showing real time fps. Also you can try to turn on gsync indicator in control panel.

I have high admiration for the knowledge of Ianrivaldosmith and I used this gentleman's advice on many occassions.

But this time I have to partly disagree.

In my case the V-Sync option within MSFS does disable G-Sync, BUT only in the 1/2 refresh rate ("30 fps") or 1/3 refresh rate ("20 fps") options. If I run the V-Sync within MSFS combined with the full monitor refresh rate ("60 fps") option, then g-sync stays enabled and works as expected. When the framerate hits the NVCP ceiling (coincidentally 60 fps in my case), the monitor refresh rate stays equal - 60 Hz, although the monitor's max. refresh is 144 Hz. If I am just under or just in the clouds (on ultra) and the framerate drops to 40-60 fps, the monitor refresh rate follows and uses exactly the same numbers for refresh rate.

I verified this by:

a) switching on the green g-sync indicator in NVCP - it is on for "60 fps" and off for "20 fps" and "30 fps".

b) using the monitor's OSD, which at the moment of activating shows the actual refresh rate - it showed the actual values of Hz equal to the actual fps for "60 fps" and it showed 144 Hz for "20 fps" and "30 fps".

 

My NVCP settinngs are:

G-SYNC enabled for full screen mode

Max. frame rate   60 fps

Vertical sync        Use the 3D application setting

My MSFS settings are:

V-Sync        On

Frame rate  "60 Fps"

Off-screen terrain pre-caching    Ultra

---

Render scale    100

Terrain LOD     200

Clouds        Ultra

Other graphics settings    High

---

This combination of settings in NVCP and MSFS gives me the smoothest experience with no judder and only very, very rare stutter while fast panning or rotating the view. No tearing. I tested also all other combinations but this turned out the best for my hardware. 

I also tried the Blurbusters' recommended settings from their 101 for g-sync. Their advice to use an external frame limiter (NVCP in my case)  with g-sync was worth gold! I also tried to use the NVCP V-Sync as they recommend  instead of the MSFS V-Sync but it feels to me that V-Sync within MSFS works smoother with g-sync.

My hardware is:

LG 32GK850G (monitor with in-built g-sync module) in 1440p

RTX 3070 on 511.79 driver

i7-10700K, 32GB RAM

 

Have a good day to you all and thanks in advance for any potential feedback,

David
