Totally agree with you having tried all configurations. I think I said earlier that FPS has little or no effect on smoothness.

I personally set my monitor refresh rate at 120Hz and put 20 on vsync, so i can get 40FPS smooth as silk.

That’s interesting, I may try that combination at some point. It would be an interesting comparison with 60Hz/30 FPS. My TV can do 120Hz refresh rate. Those whole number multiples are what matters for syncing to be smooth. If you hardware is up to it then 40FPS locked is certainly a great place to be.
Install open xr toolkit. You will be surprised
I tried this 120Hz VSYNC 20(1/3 RR locked at 40FPS) out this morning, but ended up reverting back to 60Hz/30FPS. Would need to play around with it longer, but some quick observations -
- I’m using a 4K UHD LG TV for display (with 120Hz HDMI 2.1 ports)
- In NVCP you need to change display type from ‘TV’ to ‘PC’ in order to get 120Hz as a choice at 4K res. on TV setting it just shows max 60Hz.
- At 120Hz ‘PC’ setting in NVCP I seem to have to go to 4096px res in horizontal instead of 3840px in order to fill my TV screen (a 16:10 screen ratio?, I don’t know)
- In game I set VSYNC on and at 20, which yielded 40FPS, but I struggled to maintain that 40FPS, which dropped down from 40 to low 30’s on runway at EGLL
- My GPU usage went up from 70% to about 86% with this change
- Sim seemed a bit less fluid for me at this setting esp panning around view during takeoff.
Ok, I didn’t know that the values in the VSync settings in MSFS 20, 30 and 60 are converted by percentage.
If I understood you correctly, I have to activate the VSync value 30 in InSim to get to 37.5 FPS (because 75 FPS are consistently excluded and lead to frame drops). But then I have to cap the FPS in the NVIDIA Control Center, because otherwise up to 75 FPS is still reached with the corresponding frame drops. I quickly tested this yesterday. Ok, I then have a constant 38 FPS without drops, but the picture is not really smooth. Yes, it is constant but I would not call it smooth. But then I don’t need to activate VSync in the sim, because my graphics card is reduced to the capped value of 38 FPS anyway and my 75Hz monitor can’t deliver a really smooth picture with this value.
Whereby I then do not understand the sense of these VSync settings “20/30/60” InSim, since they have obviously no effect with capped frames of my graphics card. But maybe the combinations of my settings are not yet correct that there are deviations here.
Therefore, active VSync only makes sense if the simulation reaches the number of FPS that my monitor can reach from a technical point of view. I notice that when MSFS reaches 75 FPS with VSync enabled, that the image then runs really smoothly and fluidly. The visual feeling is then already great.
But of course you’re right that that shouldn’t be our goal in MSFS right now, since we should find a good compromise between constant FPS and nice-looking graphics that don’t spoil the experience when we’re approaching an airport.
Yes this is true.
I don’t cap famerate in NVCP, just in game with VSYNC. Try these settings and see how it goes except aim for 75Hz RR /37.5FPS locked(VSync 30) in game VSync only. Reset your NVCP setings before making these changes.

Just curious if you have the time and want … but have you tried the “ultra” setting for low latency mode?
Not yet! I realise that low latency mode :on is aimed at perhaps slower GPU systems. Haven’t tried ultra yet, but will do. There are a few settings I’ve wanted to tweak for a while now but when you find a smooth spot you are reluctant to ever leave it! Will give it a go though and report back.
Interestingly I think this is an interesting observation and possibly true in my case where i am limiting at 60Hz/30FPS VSync in game -
“{Low Latency Mode} doesn’t do anything if you’re already limiting FPS to something your PC can maintain in the game you’re playing. All in I’ve just ditched {Low Latency Mode} entirely. I leave Low Latency Mode Off for maximum compatibility and just set a frame rate cap in games that my PC can generally maintain. The result is a much more consistent experience and generally much better latency.”

Interesting you don’t mind 20 fps. I usually lose smoothness below 30.

For me if I had to pick a number I want to be above it’s 27fps, once you get below that for my personal feel it’s a little too slow. It’s not even a visual it’s input lag at that point, it’s like the point where you have to adjust for control inputs.
Yes, below 25 for me was noticable for me. The thing about locking at 60/30FPS is it can feel like so much more. It just becomes fluid.
@RobedBadge93725 - I’ve been running the OXR Toolkit since the day of its release. If does wonders to eek out more performance of the GPU. This, however, does not help when the computer is CPU bound. In my case, I prefer to use VR with motion reprojection enabled. From what I’ve read, motion reprojection is taxing on the CPU, not the GPU. To get good buttery smooth VR performance while in busy scenery and photogrammetry cities, there is a balance required between the CPU and GPU.
Ok then you know
I have the same cpu.
Only a 3080. I run 100/100 lod 200 most ultra.
Reaching 25/33 fps…
I thought it could help you too but if you have it great!!
If I disable motion reprojection, I can easily tweak settings to get 30+, sometimes up to 45 FPS, depending on where I’m flying. For me, however, I’ll take motion reprojection locked in at 22.5 FPS over 45 FPS without it every day of the week!

You also have in i7 10700K? If you’re interested in trying something, I’d like to hear your experience / opinion. In OXR tools, set your custom render scale to 60% and Motion Reprojection to auto. Leave your in-game and OXR Toolkit graphics settings the same. I know 60% sounds crazy low, but OXR Tool’s calculation of resolution is very different than those of the in-game render scale or the OXR Toolkit’s render scale. 60% custom render scale within the OXR Tools settings produces a final resolution (2444 x 2388) that’s still HIGHER than the G2’s display’s resolution (2160 x 2160). I’d be interested in hearing if you experience the same buttery smooth VR that I get, even when in most, but not all, busy scenery / photogrammetry. You will of course see wobbly props, but that is easily fixed with prop mods available on flightsim.to.
I’ve just experienced the three best VR flights I’ve ever had in MSFS. I’ve accomplished this by forgetting about my GPU and tuning MSFS for my CPU. I’m now a firm believer that the CPU is the key to smoothness; the GPU settings may then be moved up to max out the available beauty within your CPU’s limits.

Sounds like a good plan,how did you tune CPU for MSFS? Just curiuos.
It is more like tuning MSFS for your CPU.
Grabber’s posts in this thread are the best walkthrough I have seen. I try to do better in my own posts, but I fall short.

Well spotted my deliberate mistake 
But I am still curious.
