Ctrl-F Full Screen Display can significantly raise core temps

Post by den »

...
Ref: PWP 8.0.exe 181215/181216 and msi 181213

FYI

Inadvertently left the PWP8 Full Screen display mode [Ctrl-F] on while getting a cup of coffee. Upon return, the core cooling fan was obviously at a high rpm.

Subsequent investigation indicated a significant rise in processor core temperature starts if the Full Screen display is left on for a minute or more. Not sure but believe the Desk Top Mgr is using high CPU.

Should not be more than the usual idle loop. It sits there processing Windows messages until it sees a keystroke or mouse click.

Maybe this helps:
It takes one thread of my 4 core/8 thread cpu.

For my Win10 Home 64-bit OS, latest updates for December 2018 and the CPU/Core described below:
1) Core temperatures rose from 35C before to 67C after 1 minute of a Ctrl-F Display

Maybe some other task was running in the background,

If there is, I can't see it immediately after turning off the Ctrl-F Display to see the Resource Monitor dialog... ...the tasks are displayed in descending order of CPU usage and there is nothing approaching the 24% ave usage of PWP8... ...and I cannot resolve the difference between the total CPU usage 46% and the 24% PWP8 usage.

So if this not occurring with your system/OS, don't spend anymore time... ...I do not intended to maintain a Ctrl-F Display for more that a few seconds under normal usage anyway.

Might be nice to have a Full Display comparison feature [Blink] for PWP8 for those using single monitor displays...

Sounds like malware mining cryptocurrency in your idle loop or possibly something more benign. Others do not seem to be seeing the extra activity.

I'm sure you've already done this, but one thing to do to diagnose such performance issue is to start Windows without all the start-up items in the background, i.e. run msconfig.exe and select the following options before restarting the computer:

This at least establishes a base-line for comparisons.

Another thing I do is to run the Microsoft/SysInternalsSuite utility Autoruns and activate the VirusTotal scanning of startup items. This may come up with false posutives, but those are rare.

Thank you "mjdl" for the suggestion of "autoruns". "No threats" appear among the startup files it listed using "VirusTotal.com" definitions.

I also used Windows Defender (MPCMDRUN.exe) with its latest definitions in Full and BootSector scans resulting with "no threats"

I also used "MRT.exe" (Malicious Software Removal Tool) and "MSERT.exe" (Safety Scanner) with their latest definitions in Quick Scan mode; again both resulting with "no threats".

I also used SFC (System File Checker) and DISM (Deployment Image Servicing and Management tool) to verify, repair, and confirm system files for the latest Win10 (version: 10.0.17763.1). All operations completed successfully and as far as I know, no corrections were made.

Checks for RootKits were made with the latest 'free' versions of Kaspersy "tdsskiller" and McAfee "rootkitremover". No threats found.

I also tried without success, a Windows Defender Offline scan using both the system User GUI and an Administrator: Windows PowerShell [PS C:\WINDOWS\system32> Start-MpWDOScan]. I did not take the time to create and do from a separate boot-able source.

PWP8 with a Ctrl-F Full Display will still use an average of 22-24% per minute of the CPU [indicated by the system Resource Monitor] with other system process excursions adding to peaks.

I do not consider this a concern as I do not intend to use full screen display for more than a few seconds.

I also observed that PWP8 will use considerable amount of CPU when doing "hand grab" moves of one of the dual displays at 1:1 viewing. Again, this is just an observation and not a concern.

If anyone would like further information regarding the system scans performed, ask... ...other suggestions for checks are welcome.

I think you've done all the <understatement>reasonable</understatement> checks for malware!

Maybe this is a video driver thing: if you've installed the video card drivers from the manufacturer, rather than just the Microsoft Update versions (this is what I had to do in order for PWP8 to recognize the Nvidia CUDA capabilities, Microsoft Update was several versions behind), try reverting to the official Microsoft Update version.

But as you said, the ROI on this kind of fussing around is pretty minimal.
