Thank you for the information!
The minimum GPU system spec for using the game is GTX 560, we had to compare and sharing our findings: benchmark comparison between GT 1030 and GTX 560, you can see GTX 560 is performing a bit better, so we're pretty pleased to know you can run 60fps on medium settings on lower requirements than our minimum for GPU, especially since that the minimum requirement aren't meant to provide 60fps at Ultra/High.
We plan on optimizing the prologue better and this info was very helpful. :)
