Then I'm sure you'll have no problems demonstrating this. Please show me an example where SSR looks different between AMD and Nvidia in the same game. For example, Quantum Break also uses screen space ray traced reflections. Shouldn't be too hard to show a difference in reflection quality between AMD and Nvidia. Or from Battlefield 5. Or any game for that matter.
