superhigh cpu load in videocalls

hi guys,

 

I am setting up the following system and get superhigh cpu loads when making video calls, like 90-100% and choppy playback and even when just using audio the CPU goes up to 50-60%.

 

My system is like this:

Windows Vista x86 with al the latest updates

AMD Athlon XP 2600+

1 GB of memory

Logitech c270 webcam

 

I have tried reducing the resolution of the webcam, but dont see any improvement in the reduction of cpu load. still high.

 

I have attached all the necessary debug logs. hope you can help.

Re: superhigh cpu load in videocalls

What version of Skype are you running?   FWIW, it seems that the beta version, 5.7.0.123, may be a little lighter on CPU resources. 

 

www.skype.com/go/getskype-beta

 

  Older versions, going back to 4.2, also used less CPU if you want to give that a try.

Also, if you want to post logfiles for Skype, you need to do so in the developer's Jira forum.  Nobody here will be able to read them.

I’m not sure how much this will help with your Skype problems, but definitely, 1 GB RAM is very little for aVistasystem, especially with a graphic card using shared memory. Maybe just extra 1GB will help.

Re: superhigh cpu load in videocalls

thanks ruwin, but the system is only using 500-600MB of the total 1 GB. So no shortage in memory there.

 

and I am using a Ati Radeon 9500 Pro AGP8x videocard and not the onboard videocard.

Re: superhigh cpu load in videocalls

I have the same or similar problem.  I have a new core i3 laptop running win7 and 4GB RAM and usb logitech C270 webcam.  If I set thread affinity on skype.exe then during a video call the cpu slowly ramps up over 20 - 30 seconds to use all of the selected core.  Other cores (or Hyper Threads) are also used but at about 10-20%.  System.exe and umvpfsrv.exe are the next highest cpu apps in task manager.  If I disconnect the webcam then re-connect, then cpu useage goes right down and then will sowly ramp up again.

 

It can obviously run at a low cpu useage as it does at the start.  Something is going wrong and causing a processor loop (either Skype or the webcam drivers).  Everyhting is up todate with latest skype and webcam drivers.

 

It is driving me round the bend.

Re: superhigh cpu load in videocalls - RESOLVED

[ Edited ]

I found a logitech support forum with a fix.  It is the latest 2.30 drivers that are the problem.  If you downgrade to the 2.27 drivers then it appears to be OK.

 

direct link to 2.27 drivers mentioned in forum article

http://forums.logitech.com/t5/Webcams/BSOD-0x1000008e-in-lvuvc-sys-for-Webcam-C270-on-Windows-7-SP1/...

 

uninstall current drivers and install this older driver (I just installed the driver and not bundles software).

 

CPU at 18% (was 40-50% over 4 cores)
