AMD revealed that customers are now experiencing a 3-15 percent performance hit when they upgrade to Windows 11. A fix is on the way.

“AMD and Microsoft have determined that compatible AMD processors may exhibit reduced performance in certain applications when running Windows 11,” an AMD support document explains. “A software update is in development to address this issue with expected availability in October of 2021.”

According to AMD, there are two problems triggered by the Windows 11 upgrade that impact performance by 3-5 percent in one case and 8 to 15 percent in the other. That latter issue impacts gaming, and AMD specifically recommends that eSports participants wait to upgrade until the fix is available.

The issues are apparently more pronounced in PCs using an AMD processor with 8 or more cores above 65-watts of thermal design power (TDP).
