What is DSR?  I see two references to it in recent posts.

DSR is essentially Nvidia's version of Render Scaling.  It upscales resolution, then downscales back to the native resolution, the effect of which (just as with Render Sclaing) makes the visuals more crisp, apparantly higher resolution text, etc.  Whilst both processes have the psychovisual effect of making it look like the resolution is higher than native, what they are really doing is applying a highly visually effective anti-aliasing process, via the upscaling, which gives the appearance of a higher resolution.

So if for example, you have a 1920x1080 monitor, and set Render Scaling (or DSR) to 120% (1.2 DSR), both processes will label the effect as "2304x1296" resolution.   But it's just that..... an effect.    It's not physically possible to see a resolution on the screen that is higher than the monitor's native capability.

DSR is older.    The first adoption of Render Scaling I saw was in Euro Truck Simulator 2.  MSFS's Render Scaling process (part of their custom engine, which is allegedly an advancement on the Forzatech engine) seems to be exceptionally well optimized.   So DSR is best avoided, in favour of MSFS Render Scaling.

PS.... Using values less than 100 in Render Scaling, has the opposite effect, it dowscales the image, then re-upscales back to native.  The result is the "removal" of some AA effect, but the advantage is a performance increase.   (And when using high resolution like 4k, the downscaled image may not be any worse than native, in terms of AA).

My screen is 3440x1440, and as I have all settings at Ultra now + SSAA at 8x, AF 16x, I can increase RS to 105 or 110 maximum is about it, and even then panning starts to suffer on the 2070 Super in the box now.  I have a 3080Ti waiting to be installed so at that point I should be able to get more out of this.  I have always use nV DSR at 2x, plus their Sharpness control and it's pretty good already. 

What I dislike the most since SU5 is blurring of tangential views.  If my view is directly forward and I look say at a 45 degree angle to the sides it gets quite blurry very quickly and when you look fairly far out it's super blurred.  If I rotate the view and look at that same spot it looks fine.  So I simply try not to look as there appears to be no way to get around this now which I assume is in part where the performance improvements are coming from.  I do have motion blur OFF but that has no impact on this.

That's how it looks on my 4K monitor.

I have certainly determined that I can satisfactorily wait out this GPU shortage.

Bert, I also have a 1080 monitor and run with v sync locked at 30 fps.  I upped my render scaling to 120 and came to the same conclusions as you did. Not sure what happened to my signature containing my specs but I have a 5600x CPU and RTX3070 GPU.

How do you find the smoothness with FPS locked at 30? I tried this a while back and while I could maintain 30fps easily panning and looking around the cockpit was not smooth. This was pre SU5 though.  The best result I can get using my 42” 1080P LED TV is VSYNC set to 60 in NVidia control panel.  Not sure if the 30 FPS thing is a limitation of my TV. 
 

Since SU5 I’ve seen my GPU & CPU usage sitting around the 55 - 60% mark. Seems to be some headroom. Will have to try tweaking the render scale once I’m back from the cottage 

I have a 1080 Gysync ,monitor and a GTX 1070  and was getting around 30ish average fps with things moslty on ultra and the sliders for detail at about 125 and render scaling at 150.. But my gpu would heat up to mid 80s .  I spent some time away from MSFS and just started re playing it and read this thread and dropped my render scaling setting to 125 and it has added 10-15 more fps on average and also kept my gpu cooler...

I have gsync enabled in nvidia control panel set to 144mhz and tried setting vsync on in game set to 30 but it did not make a difference.. So i guess Nvidia control panel overrides msfs in game settings...

So atleast in my instance render scaling seems to be the most influential setting for this game.. Maybe thats why its at the top of the screen ? lol/

You make a good point here. I have found panning a little less smooth, but I guess that may be the price I have to pay to keep my temps down.  I do find it odd that at 60 fps, it is my CPU temps going up rather than my GPU temps.

My 1070 TI is running a constant 82°C running MSFS at settings similar to yours.  I now have both LOD sliders set to 200 and render scaling at 70.  Most other settings on Ultra or High.  82°C or even mid 80's°C range is not an issue.  You are good!

Thanks for that. For my eyes render scale 130 seems to be the sweet spot for viewing the cockpit writing.

Best thing I ever did was strap a Noctua NH-D15 to my i5 9600K, that thing out performs my old Corsair water cooler. I even got rid of the crappy stock fans on my 1080TI and fitted 2 X Noctua NF 12’s and re applied some decent thermal paste. My CPU & GPU temps barely get to 60 degrees running the high end preset @ 60 FPS.   
 

I have a couple of Noctua case fans as well, I can whole heartedly recommend them. Best PC cooling fans out there and whisper quiet as well.

This. However, It could already be too demanding for the GPU.

Yeah, good idea, but I think my AMD stuff runs a bit hotter than Intel anyway. Having the case open saves me a few degrees and that few degrees will save me some electricity by slowing the fans down for mining (which my rig is doing to pay for itself when it's not simming - actually it's paid for itself in just over 6 months).

The render scale is a really nice feature.  It implements DSR in-game, which actually renders the scene at the render scale resolution, then downsample scales that image to your monitor's resolution (in image processing it's called decimation).  The decimation algorithm averages the portions of the rendered image's pixels which map to the monitor's pixel and sets the monitor's pixel to that averaged value.  This yields a more accurate final anti-aliased monitor image; thus DSR is effectively SSAA.

I experimented with driver DSR when it came out a while back, before I got a 2k monitor, and loved its results, but it had a nasty side effect in that any overlay text became very tiny as a result.  The MSFS implementation solves that problem.

At the moment I run 1440p at 100% scale with anti-aliasing enabled. If I were to run 110% or 120% could I remove the in-game anti-aliasing options and get a similar quality image? TAA really hit my framerates, but would rendering at effectively 1600p-ish negate the performance benefits?

My view is not really.  I managed to get hold of a 3080Ti yesterday and actually managed to run native 4k on a 4k monitor for the first time while easily holding 30fps.

Obviously it looked great, but when I experimented with turning off TAA, I still saw quite significant jaggies. 
I don't think TAA takes too many frames actually.  As others have said, render scale is the performance hog. 
Even with the 3080Ti, with 4k at 125% it brought it to its knees, as I expected it to really.

And your screenshots look way better than ppl with new GPU... lol

Thats because they are heavily edited lol
