To your point, Gotham Knights drops below 50 FPS in certain points when running at 4K on a 4090.This should be well known. Graphically amazing software on these limited consoles will come down to developer talent.
A 4090 can run a Plagues Tale Requiem at full 60fps with RT AND ultra settings and NO DLSS at 4K. These consoles struggle at just 30fps with various high to mid settings and without RT and with upscaling to even reach 4K.
The writing is on the wall.
