Pfft, I´m not even considering to use it... been there done that, get new nvidia card only to get disappointed by the impact on frametime and fps, waste.
Hmmm, still wondering if I have to replace my GTX 1080ti with an RTX 2080ti. Tough decision. I don't have ray tracing now, so I don't really know how beautiful it is, apart from the screen shots and videos that aren't from my own view at my PC.
