Days after Windows 11’s release, AMD has revealed that users of the new operating system that have a Ryzen chip installed into their PC may face gaming performance issues.
This is a little shocking to learn as Microsoft has really promoted Windows 11 as a better operating system for gaming when it was revealed this past June. It seems that isn’t the case for AMD Ryzen users anyway, which apparently they aren’t totally alone as other AMD chips like AMD-W11-friendly chips are facing similar issues as well. AMD is aware of that problem as they’ve outlined the known issues on a support page, check below to learn about the impact of these problems.
- Known Performance Change #1: Measured and functional L3 cache latency may increase by ~3X
- Impact: Applications sensitive to memory subsystem access time may be impacted
- Expected performance impact of 3-5% in affected applications, 10-15% outliers possible in games commonly used for eSports
- Known Performance Change #2: UEFI CPPC2 (“preferred core”) may not preferentially schedule threads on a processor’s fastest core
- Applications sensitive to the performance of one or a few CPU threads may exhibit reduced performance
- Performance impact may be more detectable in >8-core processors above 65W TDP
It’s sounding like these issues will have a significant impact on users who play eSports titles like CS:GO, Overwatch, Rainbow Six: Siege and more. Right now there is no official fix as both AMD and Microsoft are collaborating on the matter to help fix these issues. AMD’s support page adds that an update to fix these Ryzen chip-related issues will arrive sometime before the end of the month but no exact date was given. If you own a PC player with a Ryzen chip that’s been looking to upgrade to Windows 11, maybe you should hold off a little until the fix comes. There is no rush as Windows 10 users have until October 2025 to upgrade to the new OS.
