Although Microsoft hasn’t reported this as an issue, some reports have surfaced online, including one from the Hardware Unboxed YouTube channel on Twitter that claims the problem is due to the new Core Compute Die (CCD) inside the AMD processors that’s failing to match the thread scheduler on Windows 11, causing games to run at a significantly slower performance. Also, it’s been suggested that disabling the Simultaneous Multithreading (SMT) feature on the AMD processor from the Unified Extensible Firmware Interface (UEFI) almost fixes the problem. However, it’s something you typically don’t want to do. AMD has already issued a statement saying that it’s proactively investigating the reports. However, the company failed to come across any significant degradation in performance on AMD Ryzen processors running Windows 11 and 10 for specific game titles. The company also continued detailing that “many factors affect gaming performance, including the game engine, CPU architecture, GPU selection, and memory choices.” Furthermore, the statement noted that “as new architectures enter the market, we often observe performance anomalies which must be addressed by the component vendor or the game publisher. This is not a new phenomenon, nor is it unexpected.” If any ” performance anomalies are brought to light,” AMD says it’ll “implement optimizations that eliminate the variations.” However, it’s unclear when this particular problem will be resolved for affected systems. If your device is running games slower than usual and you want to mitigate this issue, you could roll back to the previous version of Windows 11 until the problem is resolved. This is not the only gaming issue on Windows 11. Microsoft has previously confirmed gaming performance issues due to some security features that require virtualization to work in the operating system. As a result, the company also recommends disabling the Memory integrity and the Virtual Machine Platform features to optimize gaming performance on Windows 11.
