NVIDIA has released the full systems requirements list for Cyberpunk 2077 for both RTX OFF and ON at various resolutions.
From the looks of it, a 3rd gen Intel Core i5 and GTX 780 is able to meet the all-low 1080p requirements but of course, we don’t really recommend you to push that low if you want to enjoy at least a lagless experience. For RTX ON, the weakest RTX cards of the last gen’s 2060 is capable of doing RT Medium at 1080p but the RTX 3070 is within the sweet spot of both RTX OFF Ultra and RT High. At that price point, you’ll get to enjoy all features while tinkering at some of the more advanced settings to get the coolest Johnny Silverlight possible. For the processor, a recent year Core i7 or Ryzen 5 3000 series are sufficient to provide smooth gameplay unless you want super high FPS then you’ll need the top models from either Team Blue or Red.
With the requirements being announced, it seems that the December release date is pretty much settled but knowing CD PROJEKT RED being CD PROJEKT RED, it is hard to tell though.
