That's exactly why I decided to get a 7800X3D + 4090.  I've had it installed for 11 months now and I've had the greatest 11 months of flight simulation I've ever had going back to 1985 and SubLogic FS2.

What are your settings, we have the same setup and I'm interested in how you set up your graphics card?

4K at 60hz, DX12 + FG
I run a Gigabyte Gaming OC 4090 card

NVCP: all default except for vsync which is ON
in-sim vsync is OFF.  I use TAA and 100% render scale.  Settings are ultra preset with TLOD at ...I think 200.  No TLOD mods right now.

Currently I'm not underclocking the 4090.  I have done that in the past because its a bit overclocked vs. standard 4090 I believe, and I don't think overclocking a 4090 has any tangible benefit for us in MSFS especially if we're capping frames for smoothness.  Right now all default settings on the card itself.

nvidia driver 551.61

In recent past I have also run different settings in NVCP, like "Prefer Max Performance" but right now I'm not doing any of that.

Thanks, I have the same card and I undervolt mine, I get little better performance and the card draw less power and runs cooler, take a look at this, I use his performance settings.

That is such a shame Noel, It has to be CPU related. For me FG is absolutely stellar, especially this last week since I have been locking fps@80 with Front Edge Sync. It is buttery smooth and I can even go down to 70fps if need be.

Don't feel bad what I'm experiencing is exquisitely sharp and stutter free, amply smooth, seriously.  It is just so nice to be rid of the two-screen issue which is no good and no CPU will fix that.  The image now is rock solid, every element of it and I've not seen this level of clarity even though I always had very decent clarity, just not like this.  Render scale at 160 for my flight and here was the result.  This is not for bragging rights, but to show it works and panning is just fine at this frame rate and the entire flight from 18K to arrival gate looked was just razor sharp and super smooth, of course.  Really, an A+ rated experience from gate to gate, no kidding:

If all you want to do is run a smooth 40 and no FG, then fine, but to me that defeats the whole purpose of getting the 4090. 

Well that's just it Rhett it's not *just* a frame rate of 40.  That aside, I find 40 very close to ideal, and in some ways actually more realistic than 80fps using FG, which I did experience for a couple weeks.  The other nice benefit is the VRAM headroom so I can benefit from a Render Scale of at least 160%.  That is really delivering a level of sharpness heretofore not appreciated by yours truly.  And again this is so so important to me:  I really find the judder when moving between screens which is a constant need for me is nothing to ignore and it's frequent.   When we finally update the base very likely instead of 38 or 40 in a demanding plane I'll be able to run a rate of 45 or 50 I'm pretty sure, which is way more than sufficient to deliver the ideal experience.  And stretch out the TLOD as well.  Sure we'll try FG again then but again a new CPU won't solve the two screen issue, and not sure if it solves the other issues described as well.  As you know some others w/ top hardware report some of these aberrations as well.

Is that with DX12, TAA, locked at 40 with "edge sync" ?

I've now tried most of the settings I've read that other people use, and my conclusion is that the settings that work best for my PC is running the card without frame lock with the following settings.

NVCP
G-Sync on at both fullscreen and window
Low Latency = Ultra
V-Sync = On

In Game
DX12
TAA
FG = On

With these settings the sim runs 100% smooth during panning and camera view changes, the only disadvantage of running the card without frame lock is that the card will run at almost 100% so there is less headroom to raise the Render Scaling and that the fans runs audibly higher, but since I use headphones it's a minor problem.

Absolutely I proved this against all other sync methods 15 months ago and it's held up since.  Not only is it subjectively totally smooth but it is corroborated by CapFrameX captures.  Of note, I noticed the smooth way before I ever knew how to capture FTV.   I have left HAGS on as I forgot to turn it off when I decided to run w/o FG enabled, but so far no downside.  I do look forward to a better CPU, but it's not critical at all now.  4090 was the best purchase to extend some use out of my 9900K it's so close to perfection now and I will appreciate some more CPU when it's time to retire this one.

Oh, and btw @Noel, since I prioritized answering your comment in detail vs completing the pre-flight flows, I'm now at least 10 mins behind schedule lol. Those poor passenger are waiting, I guess I should make an announcement and apologize before I call for pushback 😛 

Haha I know what you mean I use SLC for all flights and one must pay much closer attention so jumping over to dialogue here is why I sometimes don't score as well as I'd like 🤔

I am not trying to brag here but this is the difference with a stronger CPU and the same GPU. This was a 15 minute capture in the Fenix at ultra settings, shadows on 6144 and fps locked at 80 with front edge sync and with FG on.

Sure, we would expect to get more out that CPU.   And when one has excellent panning, stutter free, totally smooth at 38 FPS out of anywhere in any plane with razor sharp render scale at 160% and zero artifacts associated with FG you've already reached Nirvana.   I'm stoked to be rid of the 2 screen problem and all visual aberration associated with FG.  A new CPU will let me amp up TLOD, FWIW, will likely let me run native frame rate of 45 or more I'm sure.

For your example above let me know if your system can sustain at least 45 without FG.  And if using air cooling what peak temp is at 45fps.

Main reasons I'm locked at 60fps is:

• more smooth (lower FTV)
• able to run higher resolution with DLDSR - looks MUCH better than native 4K! (DLSS ultra quality makes a huge difference)
• GPU temp and fan noise much lower

Having said that, I'm currently in the A300 somewhere over France at FL340, and for some reason main thread is getting hammered, limiting FPS to around 60 with FG on. No difference between 4K and "5K" as I'm main thread limited (35ms vs GPU 10ms....). Not a huge problem as things are smooth, just strange. Could be something with the A300?

Allright so I shut down FSHud+FSLTL then AutoFPS which was running TLOD600 (as I had the headroom for it) and FPS unlocked is now 90... Still in 5K and GPU is now max utilized at 99%, main thread down from 34ms to 21ms, GPU up to 14ms.

What is your refresh rate?   144hz?  120?

I don't have that problem (the card running almost 100%) with the card fans because, when I run with vsync (in NVCP) it caps at 60 fps

I ran Low Latency = Ultra for a while but I need to re-visit that.

Speaking of headphones, in Win 11 my headphones are very very quiet despite me setting their level to 100%.  I have to yell for P2ATC to understand me.  That's a /major/ problem for me but I'll figure something out.

Not sure what this would achieve? I can consistently hit 80 fps with FG so that means I am achieving 40 before FG does it not? My current CPU temp is 52 degrees, air cooled @ 5Ghz on all PCores. Yes I know that could fluctuate like it did this morning, I was preparing for a flight at EGLL in the Fenix with plenty of FSLTL traffic and my fps on the ground dropped to 70 but GSYNC kept things smooth. Once in the air a solid 80 fps again to Toulouse and exactly the same heading from Gibraltar to Manchester

My monitor is at 144hz and the game caps automatic to 138 fps, my card runs at 95-100% because I use rendering scale at 130, regarding your headphones, they are probably too hard to drive without an amplifier.

I asked you to do that to see if your CPU could manage at least 45 FPS anywhere in any plane anytime because very likely that’s what I’ll be doing when I upgrade my CPU unless all these visual aberrations magically disappear which I sort of doubt they will and again the two screen issue is ginormous for me, so very likely I will stay out of frame generation, unless somehow that’s addressed as well.
