Hi,

I've been trying to troublehoot sudden freezes of my PC and have used LatencyMon to identify the drivers with the highest ISR count as per below



Digging into this a bit more using XPerf, it appears that my system is producing an abnormally high number of interrupts when calling DxgkpCalibrateGpuiTimerDpc in dxgkrnl.sys and also FxInterrupt::_InterruptDpcThunk in wdf01000.sys as highlighted in the DPC/ISR timeline by module below.

The question is, what can I do about this?
Can I disable DX12 or this calibration of the timer? Any other idea? Thanks in advance.
