I don't understand why people are fooling themselves. Why not run the game at lower res, the RT effects will look worse than native anyway especially reflections. I understand it is a big selling point, everyone wants to run games at "4k" or "1440p" but if your card can't do it native, why fooling yourself? It won't happen, it is not as good as native no matter how many times you'll say it is better than native.
