Not exactly a “new” pack. The OP was probably misinformed at the time of creating the thread, since there’s already a 4X zoom option, which makes graphics look awesome IMO.
In the future, it was said that there was going to be a separate download for the 4X zoom (UHD PACK), with a new update, that would (hypothetically) improve overall performance, by reducing file size for the base game (hopefully it works that way and performance indeed improves!).
