dear spacedesk developers, after updating from 0.9.78 to version 0.9.79 everything works fine but i notice significantly higher cpu usage. far below 10% under 0.9.78 and constantly 12%-13% after updating to 0.9.79.

best regards

peter

to be more precise 0.9.78 spacedeskservice.exe causes only around 0% to 1% cpu load. as a workaround i have deinstalled 0.9.79 and switched back to 0.9.78. now everything is fine as before the update.

Is this the CPU usage when spacedesk is in idle or when there's a viewer connected?
For further analysis, could you please run dxdiag.exe on your primary machine, click "Save All Information", then attach the output file (dxdiag.txt) on your next reply.

hi lea, thanks for you reply. as there is 0.9.80 available and showing the same behavior as 0.9.79 i will do the diagnosis using version 0.9.80. the system i use as primary machine is an hp notebook cpu core i7-3840qm quad core, 16gb ddr3 ram with windows 10 x64. the client side is a microsoft surface core i5-6300u dual core, 8gb ddr3 ram with windows 10 x64 and spacedesk client 0.17.0 from ms store.

the settings of spacedesk client are: resolution 1620x1080, lowest color quality, 60fps. performance is excellent.

up to version 0.9.78 the cpu usage in task manager has been 0% while idle and switching between 0%, 1% or sometimes but very rarely 2% while connected.

using 0.9.79 or 0.9.80 the cpu usage in task manager is 0% while idle but switching between 12% and 14% while connected.

i got noticed by this issues because my notebooks fan started blowing constantly while using versions 0.9.79 removed link but staying quiet while using 0.9.78 and lower versions.

i will provide diagnostic logs asap.

best regards
peter

hi lea,

pease ignore me post before as there is some important information missing. here my complete text:

so here comes the promised bunch of logs. here is the scenario in 3 steps: i did a fresh reboot of the primary machine. opened task manager took a screenshot of the two spacedesk processes and ran dxdiag.exe. the resulting files are named 1_... then i started spacedesk viewer on the secondary machine and connect to the primary machine. same procedure: first the screenshot of the two spacedesk process in task manager, then ran dxdiag.exe. the files are named 2_... and finally i have closed the spacedesk viewer on the secondary machine waited for some seconds and again screenshot of task manager and ran dxdiag.exe. the files are named 3_...

after disconnecting and killing the spacedesk processes in task manager and restarting spacedeskservice.exe in the services tab of task manager everything is fine until the next connection to spacedesk viewer.

diagnosis has been performed using spacedesk driver 0.9.80 on the primary machine and spacedesk viewer on the second machine. i hope the provided logs are useful for you. please advise if you need further information.

best regards
peter

I can confirm the same behaviour on version 0.9.79

CPU usage for the service, while a client is connected, is around 19%, that stays the same in idle after client disconnection.

Please, let me know if you need my info from dxdiag
