1.) I agree, but you aren't getting the intended version
2.) Normal colors aren't the standard , YOU are altering the colors too much by turning off things, but I do agree that some post processing effects destroy image quality TOO much.
3.) I agree with this, but again you aren't getting the intended version which is a big deal because it sets nuance like mood etc.
Lastly DLSS5 is A.I. slop filter garbage and looks horrible, artificial and eyes straining. DLSS5 is a cheap and lazy way to add fidelity and destroy art direction so that the greedy industry can fire dev teams and generate generic garbage for cheap. DLSS5 will destroy gaming. Visuals in the future should look like those actual rendered tech demos not A.I. slop.
EDIT: This is the future of visuals.
