It's difficult to know for sure. I'm getting the impression NV is dictating that non-DLSS performance is good enough at certain resolutions using higher end cards for whatever reason(s). Maybe this will change as the image quality improves.
Interesting to see that DLSS is something that will evolve so the current performance and/or image quality should improve:
"DLSS is a continuously improving feature as NVIDIA will continue to train the network and deploy new software updates."
Will try to get few hours play but initial impression albeit before installing the latest driver to go with the Dice BF5 update was that it needed some work. I noticed a lot of flickering in puddles during my 15mins of gameplay across a few maps. Will see how it plays with the latest driver later this evening.
Non-DLSS performance is nearly but not quite good enough at 1080p with RTX enabled on a 2080TI. It definitely isn't good enough @1440p. If you're not over 100fps you're not in the game IMO. The 2080Ti without RTX will get close to full time 144fps, but thanks to excess visual clutter I run lower settings in BfV (In fact since BF4 with any of my SLI setups for the same reason). Note I don't run SLI no texture lame mode though as I do consider that as cheating.
