Windows 11 is now officially here and right after Microsoft's new operating system launched, an update was pushed out that reduced AMD Ryzen CPU gaming performance by up to 15% on some systems.
Microsoft is working on a fix for the Windows 11 update, that will boost performance back up on AMD Ryzen processors. The company notes there's an issue with high L3 cache latency, which reduces gaming performance by up to 15% depending on the AMD Ryzen CPU being used.
