Fixes for AMD Ryzen performance, other Windows 11 issues rolling out to testers now
hand me my patching trowel —
Update is reportedly being prepared for public release early next week.
Now that Windows 11 is out, the arduous process of fixing the new operating system’s bugs can begin. The OS got its first Patch Tuesday update earlier this week, and now another update is rolling out to Windows Insiders in the Beta and Release Preview channels. It fixes a long list of early problems with Windows 11.
The headliner here is a fix for a problem affecting L3 cache latency on AMD Ryzen processors. According to AMD, the bug can reduce performance by 3–5 percent. The Windows 11 update released earlier this week may have actually made the problem worse, but at least a fix is imminent.
The L3 latency bug is one of a pair of problems that AMD identified with Windows 11 earlier this month. The other Windows 11 problem AMD identified, which can prevent high-core-count, high-wattage Ryzen chips from correctly assigning work to the processor’s fastest individual cores, will be fixed via an AMD driver update.
The Release Preview Insider channel is usually a Windows update’s last stop before public distribution. A post shared on Reddit suggests that the Windows update is being targeted for release on Tuesday, October 19th, while the AMD driver update for the other problem should be released two days later, on the 21st.
Other bugs addressed in the Windows 11 update include one that prevented some upgraders from seeing the new Taskbar or using the Start menu, a PowerShell bug that can fill up a storage volume with “an infinite number of child directories” when you try to move a directory into its own child directory, and a number of problems that could cause freezes, crashes, and slowdowns.
