Has 4K improved with SU11 and DLSS ?
Have you noticed any improvement with 4K ?
4k in general is worth it but that has nothing to do with SU10 or DLSS.
With DLSS the experience is worse than with TAA as it’s a downscaling/upscaling algorithm which draws textures and details more blurry - it’s basically useful on weak GPUs only.
Other than that the overall picture quality did not increase as there are still no DX12 effects used (reflections are still screen space reflections, not “ray traced”, shadows are implemented as on day 1, volumetric lighting did also basically not change from a technical aspect)
In general there is not a big issue going 4k even on RTX20 cards with MSFS - your CPU will be the limiting factor most times 
Benefit of 4k is compared to smaller resolutions more fidelity especially on large screens due to less aliasing and finer details being visible

thats a little myth … 4K needs still a good AA algorithm
But I also not know what 4K have to do with SU10. I play neary 4K and still without DLSS, its not good enough for me. There are situations where the CPU limits, there are situations where the GPU limits - but I not wonder about, because I fly with my old hardware in Ultra settings.
PS: also funny that all the answers whether 4K is worth, are already answered:

The thread you linked is an old one from last year. We’ve seen a lot of performance grains since then, I certainly have with 1440p. SU11 has improved performance so 4K could be more beneficial than it was before.
So how could all the answers be answered before ?
Things will ultimately continue to change with regards to performance especially as updates progress. So my point is a question raised a year ago may be out of date now.

yes… but I assume you own a 4K montitor , because you mentioned you switched back from 4K to WQHD. So, you can try out 4K now easy by your self 
The performance is improved a bit, but magic wonders will not happen here. User can not expect a doubling of fps in 4K. Most important are stable fps for eg. 30 ( or in my case 37.5 fps ) , and that I get often, but not allways.
Thus, 4K is in same kind worth to use, as pre SU10.
About quality diff 4K vs WQHD was already lot mentioned. WQHD is still a good compromise if you need more fps. But 4K is 4K and the quality is better.
Not really as CPU is the bottleneck not resolution/GPU in general they improved memory handling and fixed memory leaks - usually the GPUs are still bored by waiting for CPU delivering content.
No I actually got rid of my 4K monitor last year and now have WQHD. So it’s a bit hard to “try it out for myself” hence the reason why I’m asking on the forum 
in special because of these, because users which are currently CPU limited show us screenshots where the resolution not matter.
This will be may be changed if the DX12 implementation will be final optimized. But also here, some users report already ( seems depends on newer hardware ) a again better performance with DX12 because the CPU is better utilized.
ah… then it makes sense. But then it realy depends on whether you like more fps or can live with the 30’er range. As mentioned, the performance improvment is there, but not a magic wonder. And users which are former mainly CPU limited, will not get a better situation now with DLSS . But also here, it seems it depends on hardware - I get currently worse results with DX12 , compared to DX11, with my hardwre (i7-8700k,2080Ti,64gb,3840x1600) , other users with the newer cpus / gpus reported better results ( better core usage ).

This guy had better performance using 4K than 1440p.
I’d question that is directly related to MSFS. If he has a G-Sync capable display it might have had to do with this as he didn’t use the native resolution.
Maybe the displays framerate sync didn’t work well while being forced to a lower res but I’m not an expert in this case
Other than that just try what 4k will do on your system - activate DSR in your Nvidia Control Panel if you have a NV card, activate DSR factor 1.78 DL and 2.25 DL - this will provide two higher resolutions globally on your system. Select them and test the performance
The performance in general is not 1:1 in this case as it’s also some ai based upscaling, but it will provide you some feel about that.

Good idea, or he can simply just raise the Render Scale in MSFS graphic menu, to reach a 4K resolution. AFAIK it should be exactly like displaying real 4K on performance side.

DSR is not same because of internal optimizations. But a good idea in general… with the in-game resolution scale its realy easy to test. Some times the easy things are hard to see 
@CodeLoran69 … oh man, I should read faster

Ah yes, that still exists - but only if you don’t use DLSS/DLAA
AFAIK it should work also with DLSS/DLAA exatly like intended. Render Scale is the first render pass.
AFAIK but I’m pretty sure I’m right, and will be upset, but resigned if proved wrong
yes… would be also bit strange to have it with DLSS, which is a upscaler.
But back on CPU limit , its not important with or without DLSS to see whether it have an impact for the system. Of course in case @TearlessFiend27 is currently GPU limited, then it different situation…
PS: because DLAA is not DL DLAA , you can also change the r.scale … but DLAA is nothing what we want … we want DL DLAA , at least I want …
EDIT… I’am really to slow with read/write…
DLAA with render-scale present
Yup, that’s just part of my testing on SU11 I actually like the quality of aa it provides and try to spot the differences between TAA and DLAA even if it’s not DL DLAA, DLDL AA or DLAADL AADD
ah… that must you mentioned… just in these moment I wonder because I seen “DLSS → DLAA”.
Does that mean, they bring DL DLAA ?.. I expect so much from that… of course nothing for fps “lovers” , but the quality of images where I seen that in other games was very good and AA nearly history.
A clear 
from me on this - basically on my RTX20 card I see the following DLSS modes:
- Auto
- Ultra Performance
- Performance
- Balanced
- Quality
- DLAA
As it’s listed as a DLSS mode I guess it’s DL DLAA as the dumb DLAA is still in place for the AA mode besides DLSS lol. It’s swiftly mentioned in the changelog however:
Visually… well, It seems to deliver a bit of a difference compared to TAA (more fidelity, still ghosting)

The Deep Learning DLAA is like DLSS, just without any kind of down-scaling. Its the native resolution which will be optimized by the DL algorithm.
The old thing what they also call DLAA is Directionally Localized Anti Aliasing ( a good clarification ).
And thanks for the link… “Super Resolution” so I assume its realy DL DLAA
