You should never think about it this way, XVI's engine is just hot garbage.
That's why I also brought up the limitations of the PS5 because while they can be circumvented with great engines, most devs just can't be bothered and that's why we get what we get nowadays and precisely why we're slowly going back into the land of uneven performance or possibly even 30fps default.
Like XVI's devs thought it would be a great idea to bake in RT into performance mode on this hardware, yeah good luck.
There's no magical untapped potential as has been said, it's just a x86 mid-range PC in a box, though the performance will never translate 1:1 with PCs the 2070s is actually superior, even just because of the fact that it's DLSS-enabled and has better RT performance than the PS5, especially that most PCs run better CPUs as well and that makes a ton of difference.
Some Sony titles are already very impressive visually given the hardware but we can't expect games that look significantly better than that and run perfectly.
I'm 50/50 whether a Pro is coming and I don't care much unless it's reasonably priced and rather geared towards consistent fps and higher res than RT.
I absolutely don't agree that RT I just a pointless gimmick, the way PS5 does RT is a pointless gimmick but proper RT is transformative when done correctly, just not possible on such a console.
