It is easy for someone with a bleeding-edge GPU to just tell others “upgrade”, but they don’t realise that if Asobo keep this up, then their own card could become obsolete one day “just so”, without a real explanation and a notice in advance. And then have to waste days of research to find out what is wrong, only to be told to “upgrade”.
Asobo did not handle this in a good way, and even if it doesn’t get this problem fixed, we need to let them know that it’s not alright for an entire range of GPUs to become obsolete from one patch to another because of an undocumented change just two months after release, without a public and definitive statement, and with the minimum requirements not being updated.
And no, the GTX 770, GTX 780, GTX 780 Ti and the GTX Titan Black are not below the minimum requirements. And by extension, it means that the game should work on GPUs with the same or newer architecture even if performance is lower, because there is no change in the feature set.
