The tests shown in the table were performed at 1080p resolution with ‘High' graphics settings. The reason for the performance gains with Windows 11 24H2 is the inclusion of AMD-specific branch prediction code, enabling better performance all around. However, this version of Windows 11 is currently only available through the Windows Insider Program. Currently, this Windows Update is in the Release Preview Channel, which means Microsoft will be planning to roll it out to all users quite soon. In the meantime, AMD is “collaborating with Microsoft” to try and get these code optimisations pushed out earlier via an optional update in Windows 11.
According to AMD, Zen 5 CPUs will see the biggest upgrade with this Windows update, but Zen 4 and Zen 3 CPUs should also see some improvements.
