To add to that, you will have a software overhead from the emulation taking place. On top of that, the consoles are running in BC mode, so none of the features of RDNA 2 are present, such as the IPC gains and hardware accelerated RT (as confirmed by MS themselves). It's a poorly optimized game engine from over a decade ago that has a hack job of RT extensions implemented into it.
Crysis remastered on consoles is not indicative of anything.
