Uncharted looks amazing ofc, on PC even more
Remember ps4 to ps5 isnt some crazy power leap like it was in ps1 to ps2 to ps3, its 1,8tf to 10,2tf so best case scenario including newer gpu architecture 6x jump, and about 3-4x in cpu.
Just look how ps4's ragnarok runs/looks vs how ps5's ragnorok does, ofc there is difference, but from my pov graphical leap is smaller vs tekken 1 to tekken 3 on same first playstation.
Here again very informative digital foundry video and comparision between both versions
Edit: Sony Santa Monica are top tier dev team and u can assume they did best they could, simply ps5 isnt as strong as u think it is, if it was SSM would make game look like in fidelity mode but run it at 4k/60fps, yet they couldnt, they had to cap it at 30 or 40 with different mode, and there is no raytracing there even, so all the gpu/cpu oomph went into the meat.
