AMD seems to have put all its efforts into driver optimization for the latest Radeon RX 7900 video cards. The fact is that the latest Radeon Software 23.1.2 driver is intended exclusively for new products, that is, no other adapters are supported by it.
In general, an exclusive driver would not be unusual, but the problem is that it has been almost 50 days since the last driver was released for all currently supported AMD 3D cards. Among other things, during this time a number of fairly large games were released for which AMD could add optimization. For example, Radeon Software 23.1.2 has optimizations for Forspoken which was the first game to support DirectStorage, thanks to which in-game loads take only a few seconds.
