Microsoft is releasing a new Windows 11 update today that fixes some of the AMD processor performance issues. AMD and Microsoft found two issues with Windows 11 on Ryzen processors at launch, one causing L3 cache latency to triple and slower performance by up to 15% in some games. Microsoft is now fixing this particular issue with Windows 11 Build 2200.282, available today to all Windows 11 users as an optional update in Windows Update.
While the latest Windows 11 update made these issues worse, today’s patch should definitely fix them on the L3 cache latency side. The second outstanding issue affects AMD’s preferred core technology, which moves threads to the fastest core of a processor. AMD claims that this second bug could impact the performance of CPU-dependent tasks, and AMD has already released a new driver to address it.
This new Windows 11 update also includes a large number of fixes, including one to fix an issue that prevents the Start menu from opening after upgrading your operating system, and fixes for lags. input for some Bluetooth mice and keyboards. You can find the complete list of fixes that are part of this fix on the Microsoft site.
