Windows 7: Flash, video playing, sound and generally high CPU Usag


01 Jul 2009   #1

Windows 7 RC 1
 
 
Flash, video playing, sound and generally high CPU Usag

I've done a fair amount of reading and searching on CPU Usage in Windows 7 (both Beta & RC 1) and haven't had any luck with this issue yet.

The machine I'm using contains:
Asus P4P800 motherboard
Intel P4 2.8 GHz dual core
2.5 GB of ram
GeForce 7800 GS 256MB
Clean install of Windows 7 RC1 (had same problem in Beta previously)

The issue I'm having is my CPU Usage spikes up to 80-100% very often and performance of any other task during this period is frustratingly laggy. These spikes happen from even the simplest action ranging from opening the start menu, to scrolling through text on a webpage and worst of all playing video (Youtube is my benchmark tool, 80% usage guaranteed during video play). Using any web browser with 3+ tabs open is guaranteed to spike CPU usage over 50%. Multitasking in general begets a sluggish OS performance.

Some of the solutions I've read and tried:
Installing NVIDIA's Windows 7 video drivers, no improvement.
Disabling the HD Audio in device manager seems to help a lot of people, I don't have this in my device manager.
Sound drivers/devices also seem to be a leading source of CPU over-usage in a lot of cases. I've tried disabling/removing my sound card, drivers, and audio services to no avail. I initially had a sound card and on-board sound (AC97) running and disabling one of the two had a minor improvement in performance but nothing spectacular. Even with both disabled the CPU usage still spikes to 90-100% during video play, not to mention the video stutters and stops often.
I also had on-board LAN in addition to a wireless card installed so I've switched between the two, disabling one or the other with no marked improvement.
Setting the page file to manual control with a 4+ GB size setting, no difference.
Disabling AERO, using a Windows 7 classic theme, no dice.

I like to think that my hardware is strong enough to handle video streaming/playing without maxing out the CPU but if you think I'm mistaken then feel free to let me know. My Windows 7 performance score was somewhere around 3.4. I've also watched the Process Explorer extensively and I can't find any service that sticks out terribly.

Any ideas? Any diagnostic tools you guys would recommend?

OK so a bit more succinct way to describe the problem.

Whenever I play youtube videos, regardless of browser, the video stutters and loads very very slow. Even after a video is fully loaded it will stutter during playback.

Two laptops in the same house, one with XP one with 7 RC1 have no problem loading youtube videos quickly with smooth playback. So the issue clearly stems from this PC's hardware.

I don't have any problem playing video files from the hard drive.

That's the most specific instance I can use to describe the problem. Otherwise the system just seems a little sluggish, e.g. when loading web pages they load in chunks, rather than filling in quickly. Also, when moving a window quickly around the desktop the border of the window is laggy.

It really seems like a video issue that's causing this (despite the high cpu usage indicator).

Any other ideas besides installing NVIDIA Windows 7 drivers?

Build 7100.

I ran Windows Update.

I've had all these problem since the get-go, even before I installed a program. Since then I've updated the video drivers with NVIDIA's drivers, Chrome, Firefox, iTunes, and Windows 7 Codecs.

Also my Windows Experience Index scores:
Processor: 3.3
Memory: 3.4
Graphics: 5.9
Gaming Graphics: 4.9
Primary hard disk: 5.9

your computers config is a nice and enough for 32 bit os....
As you mentioned it happens when you are streaming from youtube this may be the problem.
sometimes the activx plugins from you tube or other media streaming sites is responsible for slowing down you pc. It is a common problem.


You could upgrade to newer faster and more stable builds like 7201, 7229, 7260(according to me this are stable builds and faster than 7100).

A P4 and high CPU usage on flash seems about norm to me, did you not notice that in the previous OS ?.

It is due to activx script send from the website. And microsoft send activx update through windows update. Forget activx you cant do nothing about it.

[QUOTE]How can I update my Windows 7 RC1 build?/QUOTE]

Download a new build and install..
If you need download link Pm me i will send you the links.
Don`t forget to mention which build and version, i mean 32 bit or 64 bit although according to you system specs you computer supports 32 bit.

I didn't have any youtube video/buffering lag issues when I was running XP. Although I suppose the general sluggishness of the new UI could be due to it being a bit more CPU intensive than XP was.

Dude I have the same experience as yours while streaming from youtube(While i was using RC1 build).
I really think that your performance lag is due to the activx issues.
