I have been using that secondary scaling set to 2 for a couple days. It does work for me, everything is steady. In DLSS quality and also in TAA in and out of default JFK. I can't use DLAA with my low budget system because performance loss. I can even spin the outside view by throwing a rocker right and left and it's steady and smooth. Running one 1440p monitor.

I made 4 copies of that file so that I can restore the 2 setting in sec scaling before starting up MSFS. Because any change in MSFS options in the sim will over-right that file.

It is obvious that those reporting good results with setting the secondary scaling to 2.00000 have a 1440p (or lower res) monitor. For 4K, it seems to be too much even for a 4090 to handle in certain scenarios. 

And: it might be, what I always observe: the smoothes sim you get if you have evenly balanced out your settings between CPU and GPU limit. If now people see a smoother sim using this "tweak", my guess would be that they simply changed the balance between CPU and GPU load for the good (without knowing it). In my case, back on my 1440p monitor, I increased render scale until my rig was out of predominantly being CPU limited and bam, sim was smooth. Now with 4K it is a different story, I had to readjust everything from scratch (and I am not entirely there yet). Load on my 4080 of course increased remarkably when switching to 4K and sadly (different story), those 16GB VRAM are now kinda limiting...

Not for me,

I run the sim at 4K on a 120Hz 55 inch Sony TV, once I changed from TLAA to DLSS Performance with secondary scaling at 2.0 I was seeing zero issues

I'm fairly sure the smooth performance is a placebo effect. Your PC is likely brute forcing it without your noticing, and variance in conditions is doing the rest.

As per my lengthy reply earlier lol I do not suffer with bad performance, what I did observe yesterday is that my GPU usage was a little higher which is a good thing and with the exact same settings my FTV was more consistent. I realize now this is not new, it just popped up on my YT feed so I thought I would check it out. I did a quick and dirty test in the Max 8 yesterday and had similar results, the key thing here is that the glass cockpit blurriness is no longer there which I really did not like hence why I stayed on TLAA. Maybe I will stay with this for now, using the power that my 4090 has is not a bad thing after all. It will be interesting to test in other situations and other aircraft, I don't know what magic the Fenix team have done under the hood but for quite a while now she has been my best performing complex add-on, I hope iFly can work some of that same magic into the max 8, don't get me wrong she is perfectly flyable but not quite up to the level of smoothness I see with the Fenix

Well, because DLSS performance renders the image at exactly 50% of the original native resolution, means using 4K with secondary scale 2.0 plus DLSS on Performance results... again in exactly 4K, what you had before. So rather unlikely that performance is affected when using de facto in both scenarios the same resolution 😉  

I was referring to those that do not change the setings they have but only change secondary scaling to 2.0, which basically doubles the resolution (as shown by the screenshot from @Cpt_Piett

Btw, I learned from @Noel this week that it's possible to assign key binds for decrease/increase FPS lock with RTSS,

I'm so glad I discovered why this wasn't working for me.  If I were using DLSS FG I wouldn't need a dynamic adjusted FPS lock so as someone who stays in native rendering it's very useful to maintain my >= 10% under wide open so comes into play for example coming into an airport that might threaten my base locked rate of 45 and of course the useful part is you can change the lock w/ a key press while the sim is running so no need to stop and change the locked rate.

I definitely have confirmed its the sharpening tools of which I have most maxed out that leads to the strobing I get near the aircraft in high contrast condition that is so distracting I've yet to complete a single flight using DLSS FG I always end up restoring my normal settings usually before proceeding with taxi.   This being said if switch from TAA + AMD FIDELITY FX 200 + RS 150 to DLSS Super Resolution and DLAA the strobing diminishes substantially enough to use it and so be able to set the native rate to 30 x 2 = 60.  There are places where this is useful for me but very few as I'm able to run at 45 fully sharpened almost everywhere now.

Does anyone know what the advice in the video actually does? They recommended replacing SecondaryScaling 1.000000 with SecondaryScaling 2.000000. 

Don't waste your time with the YouTube click bait garbage!

These YouTubers just want clicks for there revenue streams!

Everyone has different hardware combinations and one persons recommendations will never fit all!

I asked this question recently but nobody could give a reply - what do primary and secondary scaling actually mean, or do?

Primary scaling, or render scaling, adjusts the resolution at which the game's graphics are rendered. By reducing the primary scaling, you're essentially telling the game to render fewer pixels per frame, which can significantly boost performance but lead to a noticeable loss in image quality, particularly at lower resolutions.
Secondary scaling applies additional post-processing effects to enhance image quality. It affects anti-aliasing and helps smooth out jagged edges. Primarily, it affects the resolution of cockpit instruments and other 2D elements within the game. Increasing secondary scaling can improve visual clarity and fine details. It generally has a lower performance impact compared to primary scaling.

Ah I see,

That is exactly what I saw when I first spawned at the gate, my FPS with FG were around 34 which is not bad considering my poor 4090 was rendering the sim at 8K with TLAA LOL

My takeaway is that my GPU has more work to do using this method which is good, not so much it is pegged at 100% all the time though. The shimmering is all but gone and the glass cockpit displays are just as sharp as they are with TLAA.

As someone who literally cannot stand the visual artifacts I get using DLSS FG (so rarely use it) I don't even know what 'shimmering' is relative to TAA.
