The most recent driver for Legacy graphics cards was released almost 50 days ago
AMD appears to have focused all of its efforts on driver optimization for Radeon RX7900 video cards. Radeon Software 23.1.2 is only for new products. Other adapters cannot be used by it.
An exclusive driver is not unusual in general. However, it has been nearly 50 days since the last driver for all AMD 3D cards was released. AMD could optimize a variety of large games that were released during this period. Radeon Software 23,1.2 contains optimizations for Forspoken. Forspoken was the first game that supported DirectStorage. It makes in-game loading take just a few seconds.
