IT House reported on May 22 that although they will not actively observe the occupancy of hardware resources when playing games, some geeks and reviewers will pay attention to these data.
During testing, developer CapFrameX discovered that Microsoft’s support for AMD Ryzen 7 5800X3D was not perfect, such as he encountered a strange anomaly in Shadow of the Tomb Raider (SotTR).
In one scene of the game, Windows 11 showed an unusually low CPU usage, with only one of the 16 threads showing correct usage, while all other threads were under 10% utilization.
Although CapFrameX noticed this problem, he is not sure what caused it:
Windows 11’s core usage reporting is completely broken. For this particular scene and setting of SotTR+, it should be > 80%.
What happened? ? Has a recent update changed the timer’s behavior?
As you can see from the screenshots, CapFrameX uses its own tools to monitor in-game, alongside HWiNFO data. The numbers displayed on the screen show that the 5800X3D has one core that hits 77.9% occupancy, while the others are almost all in single digits.
While this bug may be specific to one or even one application, CapFrameX insists that it is present in all games tested:
It is worth mentioning that CapFrameX and HWiNFO also operate based on the mechanism of Event Tracing for Windows (ETW). Therefore, he thinks that there may be some kind of bug in ETW that is causing this erroneous reading.
In addition to this, we also found another thread on the Microsoft forum where user “@AndreasRes also reported a similar issue. In this case, we can see the CPU in the performance monitoring tool or task manager in Windows 11 Occupancy was very high, hitting 100% at one point, while non-ETW-based tools like the Xbox Game Bar and the MSI Dragon Center that came with the motherboard were much more normal.
It is worth mentioning that CapFrameX was tested on the latest Windows 11 Beta Channel build 22621, which is not unexpectedly the upcoming 22H2 version.
