I'm on a 2060 Super(~2070) and I was having an issue with the game seemingly not scaling with resolution correctly. At 1080p/1440p/4K they were all looking similar and I was getting superior performance to what I expected(40-60fps). Then I remembered that some DLSS games will scale from the Windows text and apps Scale option. Let's say you're on a 1080p display using DSR to get to 4K and your Windows display settings scale is set to 300%, your target game resolution will be set from that, not 4K. IIRC the RTX Star Wars demo does this too.
Also, despite this being a packaged project, it's still doing some form of shader caching. The first time you run it, it will lag and stutter, then as you've cached everything it will become extremely smooth and load faster.
P.S.- I'm pretty sure the lowest base resolution allowed is 720p. That's why all the different resolutions I tried performed nearly the same. During one of the first runs of the .exe version, GeForce overlay screenshot pooped out into a separate folder and it was 720p.
