At first, from Ubisoft, they seemed very reluctant to talk about this topic, but they have finally confirmed that all versions of Far Cry 6 will have a feature available in 4K.
A week ago, Ubisoft was responding to users – potential and future – players of Far Cry 6, that only the versions of Xbox One and Xbox Series X will be compatible with 4K Ultra HD. Later they updated these same statements since they referred to the versions of those that had information – in this case, those of Xbox – and that of others – PS4 and PS5 – they could not comment on anything yet.
Now it seems that this information has changed again, although for good for users of Sony consoles. Since in the trailer, in addition to the revealed covers of Far Cry 6 on Xbox One and Xbox Series X, it was only indicated that these in these versions could be played in 4H Ultra HD.

However, according to information that has come to us from the Cultured Vultures portal, it seems that they have contacted Ubisoft themselves, who have confirmed the following: “To clarify, Far Cry 6 will be available on PS5, PS4, and PC in 4K. More innumerable articles on this will be available later.
So, despite what has been seen so far, everyone will be able to play Far Cry 6 in 4K. More technical details will be revealed later, although PS4 Pro might not be able to reach a resolution of 3840 × 2160 if you consider what Far Cry 5 came up with, which was 2880 × 1620, something it would come to PS5.
From here it is only a matter of waiting for closing dates in which Ubisoft gives us a little more information about Far Cry 6.
“ Nintendo inquirer” will provide further updates when more information is available.
