AMD has announced a branch prediction optimization for its Ryzen processors, now available for Windows 11 version 23H2 through an optional update. This update targets AMD Ryzen processors built on the Zen 3, 4 and 5, enhancing gaming performance on regular Windows accounts, including non-local (online) accounts. Users can find this update under "Cumulative Update Preview for Windows 11 Version 23H2 for x64-based Systems (KB5041587)" in the Windows Update section. Applying the update requires a system restart.

With the implementation of this update, gaming performance between Windows 11 versions 23H2 and 24H2 should be consistent. The branch prediction optimization introduced in Windows 11 24H2 has been backported to Windows 11 23H2.
