Well the runway textures, for tarmac and concrete runway anyway, are added textures on the ortho so they only need to change it to be treated like other objects. I’m only running it on a 1200 monitor but I could still run it at 4k using DSR and take screen shots to compare.
Wouldn’t the DSR upscaling be something done after the game AI has generated the basic 1920 x 1080 scene and the DSR just interpolating between pixel values generated in anticipation of a the lower resolution. That’s a test, IMHO, of how good the DSR upscaling is. It would be better to give the sim AI the chance to produce its best effort “knowing” it has a 4K display to handle. If there weren’t a real difference, we’d just watch upscaled DVD movies and there wouldn’t be any demand for reissuing movies in Blu-ray (where they go back to the source material - which is essentially what the sim would be doing with an RTX 2080 Ti, one would hope!
I thought DSR is rendering it at the higher res and then just fitting it to your screen res, there’s no interpolating going on like upscaling of a DVD film? If you DSR to 4K, you are selecting 4K in the game as your res so everything is being rendered at that res and just downsize to your screen. Taking a screenshot then give you the 4k image which has been generated, even though that is not exactly what you have seen on your screen.
I just got the AI advice that we should PM each other instead of hogging your thread. Since you mentioned going to 4K but were only using 1920x1080, I wrongly presumed you had a 4K monitor but not a card that could generate 4K and DSR was upscaling. I think downsampling from 4K is just the upscaling problem in reverse-interpreting what to use from 4K by interpolating the best average value for the pixels you throw away. The most interesting thing would be what the AI does in generated a zoomed truly 4K image-not sure a downsampled 4K image would tell much. It’s too bad if one’s card can generate a 4K image that there is not some way to just have it show the runway part of the image, which certainly has dimension less than 4K and could be shown at 2560x1440 or 1920x1080, most likely. If there were some way to send a generated image directly to a file, can’t programs like Adobe Photoshop handle images with dimensions larger than one’s monitor resolution by showing only part of the image at a time.

Not knowing the exact details of DSR it’s hard to say, but a higher res means everything looks sharper so on 4k the runway would still that bit less sharp than the rest of the scenery, but it doesn’t matter how much more you sharpen it from what we have now it’s not going to recover the smeared detail that comes in.
Of course you can view larger images on a smaller res monitor but if you view them at 100% you would have to move a way from the screen a bit to give a similar view to a 4k screen at the same distance, or you could just put the screen shot on a 4k TV if you have one.
with the drone camera instead of zooming, just fly nearer?
I think the following picture shows unequivocally that runway objects vs. building objects, neither of which were presumably handcrafted here, are just rendered by different methods at a different resolution.
Moving closer with the drone camera still at 92% zoom is better than going to 4K! The difference in distance (ignoring that I didn’t go to the same altitude is ~1.15 nm/0.33 nm or 3.48 times closer. My same monitor screen resolution is then being applied to an area ~ 12x smaller, i.e. (3.48^2), or in other words, viewing the same screen area magnified here as compared to how it would look at 1.15 nm (my previous pix), I theoretically have 12x the object resolution that I had in previous example pix above.
I made one change in my graphics settings. I increased rendering from 100 to 200, which knocks the dickens out of framerate but really does improve the resolution compared to a 100x rendering.
So in this better than 4K view (much better than from 1.15 nm), we can see that the buildings are still incredibly detailed with the very close-in zoom. Perhaps they’re vector-based object generated with standard vector color patterns? Perhaps runways from aerial or satellite data just get raster-based textures? The amount of pixelation is less or the pixels are more sharply rendered in the runway when it’s rendered at 200x, as it is here, vs. when seen at 100x render.

Edit_Update: The following two YouTube clips seem to support the idea that airport runway surfaces are heavily raster-based textures but that buildings, unless based on photogrammetry, are built from the ground-up by AI and textured by AI and based on the animation, would appear to be vector-based.
