Windows 11 and AMD processors: the reduced performance bug is fixed
Microsoft has released an update for Windows 11 today that fixes the performance bug with AMD processors.
The problem was that performance could be down by 15% after installing the new operating system.
Update to fix the performance bug on Windows 11 with AMD processors
Earlier this month, Microsoft and AMD announced that they were working together on this performance bug with the latter’s processors. The problem was related to the latency of the L3 cache, which was multiplied by about three. The programs that suffered the most were those sensitive to the access time to the memory subsystem.
A first update of Windows 11 was released last week and the performance bug with AMD processors got worse. Fortunately, today’s patch allows to find a normal situation, without degradation. It can be found in Windows Update, it is an optional update.
This new Windows 11 update also includes a large number of patches, including one to solve a problem that prevents the Start menu from opening after the operating system update. There are also fixes to input delays for some Bluetooth mice and keyboards.
Note that a second bug concerned users with an AMD processor. It also affected the general performance. But AMD has already proposed this week an update of its driver (version 3.10.08.506).
