Windows 11 CPU Usage Reporting is Apparently Buggy, Including on Task Manager

An anonymous reader shares a report: While not every user is actively monitoring hardware resource usage when gaming, enthusiasts and reviewers often turn the stats on to see how certain games and other applications are being handled by the hardware. During such a test run, CapFrameX, which developed a useful frametime analysis tool, noticed a weird anomaly when gauging the performance of the Ryzen 7 5800X3D on Lara Croft Shadow of the Tomb Raider (SotTR). The processor usage reported on Windows 11 is seemingly unusually low in one of the scenes in the game which is typically known to be quite intense on the CPU. Only one out the 16 threads seem to be reporting the correct usage whereas all the other threads are under 10% utilization. CapFrameX notes the issue though it isn't sure what could be causing it: " The core usage reporting on Window 11 is completely broken. Should be >80% for SotTR + this particular scene and settings. What happened? Did the recent update change the timer behavior?"
