I don't understand the point of these manipulations. What's the point of upscaling and then downscaling to get to the same native resolution?

I just tried in GPU limited conditions and TAA + native performs much better than DLSS Quality + 1.5 secondary scaling for me.

 Sounds more like people are trying to chase what DLAA is doing with DLSS, instead of simply enabling DLAA? 🤔

The way I understand it... DLSS renders at a lower resolution, that means GPU do less work.  GPU create more frames. 

Quality DLSS setting is 67% and Performance setting is 50% of your monitor's original resolution.  DLSS renders at this lower resolution which is easier on the GPU.  DLSS adds some pixels based on an algorithm, which in turn makes the displayed image look more like 100% resolution.  Cool.  That's DLSS.  67% of your pixels at Quality setting are rendered by the GPU and 33% are added with the algorithm.

There is a gap between 67% and 100%.  If you want to slide an extra setting in there you can hack it by increasing the SecondarySacling.  This is no different then that TAA slider where you can render at 200% (or 2.0 secondary scaling).  If you up your scaling by 50% your base resolution is now higher.  DLSS takes 67% of that new base resolution and does DLSS things.  However, you effectively created a DLSS setting we can call Quality++ which is say 85% of your monitors resolution.  Therefore your avionics are now 18% sharper and you are still rendering 15% less so you get some performance.

You upped the DLSS percentage, thus you are rendering at a higher resolution but adding less DLSS AI pixels.

An excellent explanation thanks!

Sir you are a prophet!. Thanks for making my day. I was struggling same thing, unless I found out my real resolution was 1707, inwhich had to be native 2560. An your scale method worked flawless. However i lost already 6 motnhs:)) 

Honestly I registered here just to thank to you. I spend lots of hours of my life with nvidia control panel, and fs options, restarted million times which take over 4 minutes only to start fs.. I was dissapoitted so much with amg ryzen 9 5700 and nvidia 3090 when i saw ppl with 60fps all the way green.. TAA was only option not to be blurry, but it had lower FPS. now I got all i wanted. I have fixed all 40 fps. and it is always green even in NYC with pmdg. 

thanks once again. +

Glad it helped!

*******. Imagine spending all this time chasing performance instead of just enjoying the sim. This is like a debugging class. Who has time for this?

Simmers who want to fly but get a headache from low fps or blurry images in VR (like me).

DLSS Swapper is a handy tool for downloading and updating the NVidia DLL file.  It lists all games you have that can use DLSS.

Do you know if this tool also swaps the frame generation version of the NVidia DLL file as well? There was another post and not was mentioned if you run with FG on a 40xx card you need this file as well as the standard one.  

If I use DLAA, or TAA my frame rates are reduced by almost half. I absolutely have to use DLSS.

But I'm running very high 5185 x 1440 resolution on a lowly 3070 card and Ryzen 5 5600+ cpu. So I need all the fps help I can get.

The above resolution (double wide 1440) is still less than single wide 16:9 4K resolution.
