Currently I fly the Fenix in MSFS 2024 along with deskline MCDU and FCU from Skalarki.  I recently decided to use my iPad for my ND and PFD as well as a secondary monitor for my EFB.  My main display is an ultrawide 49" curved Samsung.  I fly with PSXT and Real Traffic or Vatsim and fly into and out of 3rd party airport.  This setup looks great but I've noticed on approach and when on the ground in general, i get lots of stuttering.  I am also using Active Sky and Rex Atmos Core.  My Nvidia Settings are as follows:

V-sync on in Nvidia, off in MSFS

Max frame rate 50

Low Latency On

Power - Prefer Max Performance

In the Sim I have these settings:

5120x1440 - 100 Render Scale

TAA (I found DLSS made it worse)

Frame Generation Off (maybe turning it on?)

TLOD 200 Objects LOD 100

Texture res Ultra

Clouds High

Aniosotopic 16x

Cockpit refresh low

Since I am primarily looking out of the cockpit and on my ipad, what are some settings I should change in order to get a smoother experience?  I'm not too technical so hopefully this makes sense.  Maybe what I am trying to do isn't realistic but i thought I'd try here.   I'm open to trying anything, but wasn't sure where to start.  Thanks!

These are my specs:

ntel Core i7 12700K (5.0GHz Max Boost Clock) 12-Core CPU   32GB G.Skill Performance DDR4 SDRAM 3600MHz       Graphics Processor:12GB Nvidia GeForce RTX 3080 Ti, GDDR6x System   2TB Western Digital, NVMe M.2 Solid State

What refresh rate are you running on your monitor?

looks like 60 hz

AutoFPS is your CoPilot. It reduces TLOD automatically allowing you to have a smoother sim on final or while on the ground.

It's also about your settings. Each system is different and requires a little tweaking.

Run it @30 and 1/2 refresh rate.

I will also mention that as a test at a heavy INIbuilds JFK without the pop outs and displays as I mentioned, I am at 30 FPS.  Once i turn on Spacedesk and pop the panels out to the other displays, it does down to 15-30 fps at idle on the runway

Spacedesk has been known to cause a drop in fps.

Are there any alternatives to that to accomplish the same thing?

I don't think your max frame rate 50 with a refresh of 60 hz is useful, because in tough scenes your hardware will not be capable of 50 fps, not to mention it won't do 60 fps to match your refresh rate (60), so you're risking a stutter with that configuration.  You'd be better off going half refresh rate (30) and then running Frame Gen.   Or simply run half refresh as suggested.  Either way I think you'd be smoother.  However...

...your scenario you mentioned (ini JFK + spacedesk etc. etc.) is pretty much a hell-scenario, and I think if I ran that routinely with my hardware I'd have to do a little tweaking.   I do have ini JFK and with just about any aircraft I'm using AutoFPS there.

The suggestion of AutoFPS is a good one, that could really help you.  It's a little annoying to me at JFK, since it tends to knock down the TLOD to where I can't see the NY skyline from JFK, but then again, with realistic visibilities in real life you can't always see it from there either.  I often run REX Atmos with A. Bennett's presets (AB presets) and this sort of solves that annoyance for me.

When I change settings I usually go to the most congested area to use that as a benchmark.  It might not be the best idea but I always feel like if i can get something somewhat smooth in the worst areas I should be good.

I'll turn my display in the display settings to 30hz instead of 60 and see if that makes any difference.  I can also turn Frame Gen back on.  As a last resort I can try using AutoFPS again.  I thought i had it on but apparently I didn't.  I do recall like what you were saying, it made dense cities sparse which defeats the purpose but might also be inevitable.  Thanks

I'm open to any other suggestions because I really like this setup but need a little bit smoother of an experience!

No, no, you have a good idea...the worst places are the best places to torture test your rig, because as you say, if you can set it up to run decently there....it can run well anywhere.

I think you can keep 60 hz refresh, but in your nvidia control panel set the frame limit to 1/2 the refresh rate.  I mean, you can experiment with 30 hz refresh, but I'd try to keep 60 because you won't always be flying at ini JFK.  For example you can keep 60 hz refresh, but then set frame limit to 1/2 in nvidia control panel, and THEN set Frame Gen x2.  Frame Gen has come a long way in the last 2 years or so, as to artifacts etc. I find them almost non-existent now.

I'd definitely not do the 50 fps frame limiter.

AutoFPS is nice because it will have a very low TLOD when you're on the ground, where you won't notice it, but then progessively ramp it up as you climb out.   Of course, if you're at ini JFK with AI + complex aircraft then there's only so much it can do.  That's a tough spot there for any hardware.

I’ll give this all a try.  Is there anything in the Fenix app that I can change that would help with using pop outs on different displays?

Also frame gen can work with a 3080ti right?  How can I be sure?

I'm not familiar with the Fenix app.  I think I've only ever loaded that plane one time...I know...I know...a crime, but I just haven't had time to get back into A320 flying.

It might using AMD FSR3, which I believe is now an option in the sim display settings.  I haven't been keeping up with what the 3xxx series can or can't do though.

Note that the built-in dev mode fps counter won't show your frame gen fps (it will show native/base frame rate) unless Asobo has changed that in the last couple of months.   In my case I can tell if FG is on just by the way the panning feels (better at 60 than 30).

You could also use tools like MSI Afterburner etc. to measure frame gen fps.  I think for our purposes though, we don't really care about fps, we care about smoothness.  You should be able to tell easily.
