Hello,

i was reading alot about HPET , Timers etc. in the last Days and now im testing some configurations .

Win 10 Pro 1809
i5 9600k @ 5,0GHz
MSI Z390 Gaming Plus (HPET hard disabled with modded UEFI)
Gigabyte RTX 2070 Super 3x WF OC
16GB 3200MHz @ CL16

After i disabled HPET in the UEFI with the modded UEFI my Mouse and Games feels smoother

Now i did turn on HPET in Win with bcdedit /set useplatformclock yes and did a "benchmark"

What can u say about the 2 CapFramex Records ?
For me it feels like no difference between Windows HPET Off/On

Thank you

You'll never notice a difference in gaming.
You will notice a difference in certain benchmarks, pending the OS used and the CPU used.
Read up on RTC bug / skew.

What i noticed is that the whole Map of CoD Warzone is loading slowly(Textures loading slow) if HPET UEFI off - Windows UEFI off .

With HPET UEFI Off - Windows UEFI on the Map is loaded instantly and i have a clear and good Distance View .

If tested it a few Times in the last Hour and its always the same result



What about these LatencyMon results ? do i have to worry about the Latency Times and the high amount of hard pagefaults ?

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs): 37,60
Average measured interrupt to process latency (µs): 1,977249

Highest measured interrupt to DPC latency (µs): 36,30
Average measured interrupt to DPC latency (µs): 0,858354


_________________________________________________________________________________________________________

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: latmon.exe

Total number of hard pagefaults 3

CONCLUSION
_________________________________________________________________________________________________________
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
