DisplayFusion has some background polling jobs that run on timers to keep some system data up to date (Windows taskbar data, etc).

If you have any further questions, please let me know ]]> https://www.displayfusion.com/Discussions/View/slightly-higher-idle-cpu-usage/?ID=a0019a0b-3b7e-45a3-9d27-612dffc96cc8 Wed, 08 Nov 2017 01:10:48 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/slightly-higher-idle-cpu-usage/?ID=a0019a0b-3b7e-45a3-9d27-612dffc96cc8 DisplayFusion I noticed a slightly higher than normal idle CPU usage and task manager sorted by CPU usage showed displayfusion as idling around ~1% (occasionally it dips down to 0.2% or spikes to 1.5%), attached are the debug info and around 1 minute of detailed logging.

Tried updating to the 9.1 beta and it seems to idle little lower than 9.0, but it could also be a side effect of 9.0 having been up and running for 3 solid days before. Memory usage was around 90 MB at the time, after installing 9.1 beta it dropped to about 65 MB but regularly fluctuates by a few hundred kilobytes. I don't know if this is particularly unusual or not, mainly I'm just curious about what it is doing in the background that is using that much CPU time and or if there is anything that needs to be looked at, I will continue to monitor it for now. It could simply be a side effect of core parking and idle CPU clocks, ~1% at 800 MHz is quite a bit different from ~1% at 4.5 GHz after all, and the CPU is at idle clocks most of the time here. Thanks. ]]>
