Help with V-Sync, Refresh Rate, and fps

Discussion Hub General Discussion

Watched and tried the video settings. No joy for me. Unacceptable stuttering. The best combination for me are monitor refresh rate 144hz, or even 165hz, V-sync inside the sim off. In the NVCP via program settings V-sync fast, low latency mode ultra, frames capped, I got at the moment 55fps but that could be lower. The monitor is Asus VG27a G-sync compatible monitor. I am though following this in order to learn even more smooth things that I got at the moment…

I also got a LOT more stuttering using the settings in the video as well, but it works for others, so it’s worth trying, for sure.

Thank you for all your valuable contributions on other threads too about reducing latency. It helped me get my head around what was important to look for instead of blindly cranking up my graphical sliders. There are too many FPS chasers out there, and many people think they need a higher end system to eliminate those stutters when you can still get stutters on the best hardware available today. It’s strange when there are potential workarounds for stutters out there.
I do wish the devs would release a settings optimiser/advisor though. There are just far too many variables in the equation these days for people to figure out & work around themselves.

I have the same monitor as you do. Not sure about your settings in game but this is what worked best for me with regards to the monitor.

In the Monitor OSD:

  • Turn on ELMB Sync.

In Nvidia Control Panel:

  • Set your Monitor’s resolution to 120HZ.

  • Turn off Low Latency Mode.

  • Set V Sync to Use 3D Application setting.

  • Set Max Framerate to Global (Off).

The rest of your NCP settings should work fine.

In game settings:

  • Turn on VSync to 20. This should lock your FPS to 40.

Now spawn in a relatively busy airport with an aircraft that you use regularly. Using @Grabber523’s excellent advice, tweak your in game graphical settings to achieve the desired GPU / CPU latency.

You need to be aware though that 40 FPS instead of 30 means that the frametime is reduced from 32ms to 25ms. You need to optimise for that.

I have found that 40FPS instead of 30FPS on this monitor helps with ghosting issues.

Give this a go when you can and see if it improves your performance at all.

Hear, hear! :sunglasses:

Until Grabber came along in that other thread with his now widely celebrated (or it should be) methodology, I would have shaken my head if somebody told me that I could reduce stuttering by putting more load on my GPU, e.g., by increasing render scaling or going from High to Ultra on various visuals.

I think the dev mode counter was intended to provide that guidance, but without knowing which setting affects which meter, it’s all for nothing.

I simply took the time to learn the language and provided the translation.

Retiring into a pandemic and being home all day homeschooling kids definitely helped give me the time to drill this stuff down and simplify it enough to share.

But I do agree that they could make the relationship between input on the sliders and output on the meters a lot more intuitive. Even just labeling the settings and what they affect would be a big help.

Thanks for the tip! I will give this a try definitely :+1:

The video instructions from Pilot Pete as mentioned above are perfect for my hardware. RTX 3070,Intel CPU, 160Hz Monitor. Smooth also in VR with G2

Already posted and discussed in this thread.

Edit: it is good advice that seems to help out most who have tried it, though!

I also figured out that HDR and Gsync at the same time seem not to work

Wow, @NFGoose, I will have to check that with my hardware. I was really enjoying my HDR from my new monitor. But thanks very much for the heads-up.

After having a smooth 30fps experience, maybe you can try another method, when your GPU can’t reach a stable 60fps.
Use “Fluid Motion” technology to greatly enhance the gaming experience

53

For me it seems 30FPS locked in Ncp and vsync off with 120 Hz Monitor works well.
Better then gsync

54

@NFGoose does setting refresh rate work better one way or other, through Windows settings or nvcp?

55

Enjoying the smoother flight with frames locked to 30. Panning outside the plane is mostly smoothed out, not completely. And inside cockpit, I’m not getting the smooth stutter free, plus getting some brief freezes. Not nearly as smooth as in the video. Of course I don’t know what his PC specs are. Anyway, today I’m going to try some of the other settings some of you suggested.

Currently, this is how I’m getting frames locked:
Refresh rate 60 hz through nvcp
V-sync on through game setting
Frame rate limited in-game, set to 30

I want to think my PC is powerful enough to offer perfectly smooth experience, panning in cockpit and outside plane.

@NFGoose Far as I can tell, HDR still operating regardless whether V-Sync is on or off. Does not gray out, or show any visual difference to indicate it’s not functioning when V-sync is turned on.

57

In my case it was the combination of gsync and which endet in CTD.

I tried
1 Gsync on and vsync off in game
2 Vsync on with 30 limit in game, no limit in ncp monitor 60hz
3 Vsync off Monitor 120hz rr and 30 fps cap in ncp

2 an 3 are same in regards to smoothness.
But i go with option 3 ,

I have tried my own version of this, and it has yielded good results so far.

After messing around with so many of the NCP settings, I ended up resetting both the Global and MSFS to the defaults as a starting point.

  • In NCP I set my monitor refresh to 60Hz (it is a 144Hz monitor).
  • In-sim settings, DX11, turned on V-Sync and limit to 30 fps. Remaining setting are Ultra (with Bloom, Lens Flare and Lens Correction set to Off IIRC)
  • I have turned off Sharpen and FilmGrain in the UsrCfg.opt file.

I am currently flying the DA40, with both the airplane mod and WT G1000NXi, around Papua New Guinea and it is a very smooth experience. The GPU is only around 60% utilization so there is headroom for more taxing environments.

I hate to use the ‘C’ word, but I think this has improved my cloud quality, removing some of the graining and pixelation.

I do still have some AA issues as other have reported, but I don’t really know what settings I should be adjusting to try and resolve this. I will say it is better with these settings than the hodgepodge I had prior. I have a feeling the AA issue may be a global issue with the sim as it is reported by a lot of users.

Switch to DX11 and give it another go.

And if you’re using VSync at 30 on a 60HZ display then no need to cap the frames in NCP. In my experience it causes more issues than not but YMMV.

Also, in my experience DX12 is not optimised yet and still needs work. I do prefer how it looks over DX11 but it’s not ready yet.

Then optimise for around 30ms GPU and 20ms CPU render latency. These are just ballpark numbers. At 30FPS, your magic number is 32ms.

This mirrors my findings. Smooth stutter free with GPU sitting at 60% (ish) so has more headroom to have higher settings like setting clouds to Ultra and also when more graphically challenging envs are found. Try going to Heathrow and sitting on the runway and panning around or JFK etc. It’s worth checking worst case scenarios with the aircraft that you use the most.
