Most playable first day release I've done. A few minor display bugs but overall good experience. I have old hardware (nVid 1080 regular, i-7, 16 GB RAM) and game runs fine. Remember all the ray tracing etc is for selling video cards. Game was developed without this stuff till the very end. The additional graphics stuff will have the bugs worked out as time goes on. Also that's why we refer to new stuff as the bleeding edge.
