Windows 11 AMD Chips Problems cover

AMD chips are having some problems on Windows 11, preventing testers of Microsoft's upcoming operating system from getting the most out of their games.

Microsoft has been hard at work developing the next version of Windows. Windows 11 will feature the debut of new features like DirectStorage, although this new tech won't be exclusive to the newest OS version. Gaming is also a big concern for this new operating system, especially with the launch of Halo Infinite arriving later this year.

Unfortunately, a particularly puzzling problem has emerged: as RockPaperShotgun reports, it appears that AMD Chips aren't getting the best performance out of Windows 11 just yet.

What's Happening with AMD Chips on Windows 11?

Windows 11 isn't exactly playing nice with AMD chips. The problem is apparently widespread enough that AMD has gone to the effort to detail the issue in a new support page.

According to that support page, there are currently two issues facing AMD chips on the newest version of Windows. The first relates to L3 Cache latency -- games are having 3-5% worse performance in most cases and as much as 10-15% worse performance in less likely "outlier" situations, some of which unfortunately apply to popular esports titles.

The other problem is with the UEFI CPPC2 "preferred core" tech -- Windows is apparently not properly assigning threads to a processor's preferred core. The support page notes that games affected by this situation "may exhibit reduced performance," although there are no specific numbers detailed on the support page.

AMD is one of the big players in gaming hardware; its Ryzen series provides a lot of bang for your buck, especially if you're gaming on a midrange budget system. Reduced performance on Windows 11, naturally, would probably affect a lot of gamers who wouldn't be able to easily swap out their hardware.

Fortunately, the support page notes that there is a Windows update and software update on the way to resolve these issues, both of which are expected to release sometime in 2021. For now, gamers on AMD chips are probably going to want to hold off on upgrading to the latest version of Windows.
