I feel like everytime I see a video about RTX performance, the performance loss is too big for me personally. Sure, it looks amazing but a decrease in around 50% is way too high (for me). Yes, if you have a high end rig with a RTX2080ti you can still run most things at 60fps and high graphical options but I don't and probably never will spend so much money on a PC that expensive so a decrease in 50% would basically mean 30fps for me (and I guess on the new consoles as well). I still prefer 60fps over 30fps /w eye candy.
But yeah, in the future, when the tech matures and the GPUs become better, this should be standard because it looks absolutely amazing.
