AMD explains, promises partial fixes for Ryzen 9000 performance problems
Briefly

AMD's Ryzen 9000 series is a new introduction with the Zen 5 CPU architecture, but performance has not met expectations, leading to disappointment among users.
The anticipated Windows 11 24H2 update is expected to enhance gaming performance by 3-13% due to optimized AMD-specific branch prediction, which was not fully operational at launch.
Currently, some performance improvements can be accessed through games and applications run in Administrator mode, though this is not typical for most users.
AMD reassured users that the Windows 11 update will not only benefit Ryzen 9000 CPUs but will also enhance the performance of older Zen architectures.
