CPU usage (1 Viewer)

Can someone tell me why the CPU usage is very high when MP is in focus and drops down when someother application is in focus?

The CPU usage goes above 80% when I have MP in focus and not doing anything (just the main menu is on). Is there something wrong or is there ways to bring down the CPU usage. The RAM usage seems to be fine (less then 300 MB).

I am running MP on a IBM Thinkpad T20 with 512MB RAM.

Everything works fine except DIVX movies.

Thanks

Your laptop doesn't have a DirectX 9 compliant graphics card so your CPU is having to do a lot of the work normally left for the GPU to handle and that is why you're getting such high CPU usage, 0% is easily achieved with more powerful hardware.

Cheers,
Smirnoff.

CPU Usage Level

Pratab,
I have issues with CPU usage as well. I hear what Smirnoff is saying about needing a DX9 compliant vid card, but I have to say that something needs to be done in MP if have the menu screen on can raise the CPU usage to high levels. I personally have only an ATI Radeon 9250 in my system which is not DX9 cmpliant, though I do have the most uptodate version of DX9 installed.

My system can have the CPU usage level slowly increase from 2-3% to 80% over a couple of hours after a reboot and the only thing that is on is the initial MP screen. Without MP running WinXP sits at the 2-3% level for hours.

What is it about MP and DX9 compliance that is required for maintaining the main MP screen?

    Hi fossks,

    i do not think that you have a problem with your CPU / graphics card. MP version 0.1.2.0 has a memory leak on some machines. I think you hit it. Try the latest CVS (prebuild on http://www.myshare.de).

    This should solve your problem. I had have this leak also.

    HTH, Flip.

    I think there is a problem with the CPU usage in the current release. I use CVS from myshare.de (mediaportal-cvs-05-30-2005--01-16).

    See this screenshot:

    cpu_usage.gif


    Try this:
    1. Start the task manager with the option "Always on top".
    2. Start MP in fullscreen. -> MP has focus !!!

    On my system the cpu usage is between 5% and 30%. When I set the focus to the task manager (that's where the red arrow is displayed) the cpu usage is dropping to 5% - 10%.

    Since some days I noticed that, because my system temps went up for about 5° C.

    Does anyone else notice this?

    (See sig for my hardware. I've installed latest xp patches and hardware drivers.)

    Flipger,
    I installed the CVS version from 30 May and the memory leaks seem to be gone. I left the MP PC on all night and when I opened it up, the memory usage from Task Manager is the same as last night. It even responds as well as when it is started up.

    Thanks for the updated version, now I feel even more comfortable putting MP in the living room.

    I'm having the same problem, I have an Acer Aspire (ATI 9200 gfx card) and MP's usage is at 90-100% when I open it (at the main menu) and I don't know what's wrong. I have an nVidia 4200 Ti on my desktop and it runs fine there.

    I have installed all the latest versions, 0.1.3.0 (release and cvs) and 0.2 and I'm having the same problem. The CPU usage drops to normal if it keeps running for a bit, but in the first minutes it's very unusable. Any suggestions?

    I tried again version 251 with same settings file as I use on 250 and 200 but find the colours flicker all over the place and it doesn't seem very stable. Gone back to 250 and it seems same as 200 - stable.
