So checking out F1 2020, outside of DLSS for RTX users there are several options to try to get both pixel fidelity & framerate. Linked, a 300% enlargement of two TAA options: FidelityFX CAS Upscaling & just the internal dynamic resolution scaling.
I'd say (clear at 100% but shouting out when blown up) the sharpening is quite detrimental & the upscaling is plain bad in one, to the point the tech should be rebranded if fixed to work well in the future.
To do my due diligence, as I have ideological concerns* with sharpening, I did turn on the nVidia Sharpening & you can get very similar sharpening (without any uneven double-wide halos from the poor upscaling) if you really want that with the internal dynamic res TAA. You can also use the slider to modify the strength of that sharpen filter!
* Especially at 4K, real-time rendering output isn't remotely softer than a film image so clearly we are already on sharp scale end. https://blog.shivoa.net/2019/08/the-sharpening-curse.html
DLSS 2.0 is certainly not perfect (I dislike the sharpening that's not currently user tweakable - something nVidia say could be offered; I've seen some distracting artefacts in most of the implementations so far) but it does get some games to a more temporally coherent & spatially dense + antialiased output at a higher framerate (in quality mode). In performance mode, it makes sharp 4K120 realistic at the cost of some aliasing (eg visible in UE4 comparison video: https://youtu.be/i5WuzatxKzM)
