The question is, does NVCPL image sharpening add input lag and does it work off CPU or GPU(or whichever it taxes more). Also how taxing is it on newer games, performance wise of course. Also, does integer scaling work with older GTX video cards or not? I've heard some people were trying to do some mod for non-RTX cards for it but did they succeed? Oh btw, I am not talking about input lag caused by uncapped FPS reduction.
