I just watched the LTT video about DLSS 5, and the main thought I had was "never mind making questionable changes to these already very high fidelity games; what would happen if you tried to apply it to some old game, like Morrowind or Half-Life?" (In other words, some game that both (a) actually needs graphics improvements, and (b) runs at so high a framerate that you can afford to cut it in half.)
