Question

Flash - CPU Usage - FPS - Frame Rate

Ok, I first want to apologize if this problem has been answered and fixed before, but I have spent days pouring over forums, and I still can not fix my problem. It requires a little bit of background first:

I can't remember how long ago it started, but whenever I am viewing a flash file (a game, videos from youtube, advertisements, etc.) My CPU usage increases to 99-100% and remains there until I close the program that is running it, or go to a different webpage. I normally use firefox, so for the longest time I was searching for the problem relating to firefox exclusively. I came across FlashBlock, and I still use it in Firefox. However, this is not a SOLUTION to the problem, just a "work around." If I actually want to view the flash content - bye bye CPU usage.

So for the longest time I focused on firefox. I completely uninstalled and removed flash and firefox from my computer, and reinstalled. I even tried it with an older version of flash, because I can't remember always having this problem, and the problem persisted. But now I have everything up to date, and the problem is still there.

Then I decided to use IE for a little bit because I was upset at Firefox. I was surprised when I was on youtube, or playing a flash game, that my CPU went up to 100% and remained there. SO instead of googling "flash firefox cpu" I just googled "flash cpu" and I have been doing some research/experimenting. I am - by no means - a very technical person or a programmer, I am an ordinary user that is upset about this problem. I went to this page http://www.bezzmedia.com/swfspot/samples/beginner/Show_the_Current_Frames_Per_Second and watched my cpu usage go up to 100. But when the animation goes to a lower fps, from about 1-5, my cpu usage goes down, but only to about 80. So what happens is I can do control-alt-delete and watch the performance tab's graph. After letting it run for a while, I get almost an perfect, symmetrical mountainous "landscape" if that makes sense - with bumps up to a hundred, and coming down to about 80. It is so consistent that I am positive my system cannot handle even normal frame rates for some reason. However, I am running on XP Pro with a Pentium 4 2.80GHz processor and 2.5 gigs of RAM and I should not even be having this problem - I can run tons of programs and not have my cpu usage go above even 50, but a flash video puts it at 100. It is ridiculous! I don't have a virus or anything, and I actually take pride in keeping my computer clean and efficient. It happens to all users on the computer as well.

Again, I am not a programmer. Is there some option somewhere that I can tell my flash content to reduce its frame rate, or not go above a certain number? It seems that many people are having this problem. I think I remember someone somewhere saying that with the newer versions, they are trying to perform "better" than an older version you had, and the frames per second increases, but I have no idea if this is true. Should I roll back to a later version, like 5? I already tried it back on version 9 but I still had the problem.

The "ideal" solution is to figure out what is going on with the frame rate on my computer. Maybe if I could just right click the flash, and tell it to play a lower fps? Does hardware acceleration have to do with this? Also, changing the "quality" of the flash content from low to high or medium doesn't affect the cpu usage - it stays at 100%.

Please help out an ignorant person if you can. I want to preserve the life of my computer as long as possible. If someone could help me - in layman's terms - I would greatly appreciate it, and so would all the other upset people googling "flash cpu problem." Thank you!

    I have similar problems (100%CPU) and oddly I can find very little about this in the forums.

    My system should easily be able to handle the videos. Furthermore if I download the videos and play them through another video player they run fine, so it is not the hardware. I originally went crazy trying to tweak my Firefox but I also have the problem in Chrome and IE8, so it is not the browser. In fact, reading what few threads I can find it seems this problem has been mentioned on Vista, XP, and Macs, so it isn't even the operating system.

    The glow app drops to less than 2fps for me. I have had videos with framerates dropping to less than 1 FPS.

    Is FP-2009 the right bug? It says 3-6% on idle on a Mac. This is not the same problem I am facing.

    we should post this in a pub forum. I don't know how the privacy of this registered forum would influence google search queries. I have to sleep now.. will think about it when I next remember to =)

    Correct me if i am wrong. Coding important but i am talking about even flash banners, my configuration is not that bad it can plays hd videos, could run flash banners too... Check this out, http://www.isbank.com.tr/ ,  this is a Turkish bank web page, in the middle you can see a banner including iphone and stuff... Even this banner makes cpu go %100...

    İf anyone like i can add screenshot...

    So the   http://www.isbank.com.tr/  website sends my Mac into a 90% CPU frenzy...

    lunaticinsane - Please refer to my earlier posts - THIS IS A KNOWN ISSUE THAT ADODE NEED TO FIX.   You need to log into Adobe's bug website (links in earlier post) and vote for bug "FP-2009" to be fixed.

    Hi,

    I was just looking on web to find out if someone having the same problem like me... I am using windows XP on my athlon 2600+, 768mb ram, nforce2  and ati 9600xt configurated computer. I am having the same troubles, which browser i use if a flash content (whether it is video or a banner) i got 100 percent cpu usage (even i write this message)...I hope Adobe is aware that this problem is not effected only Mac users...

    i don't think there's any flash on this page.  so if you're getting 100% cpu usage from this page, you have problems beyond a flash issue.

    I was watching a video by that time

    All non flash content sites works well, i hope Adobe works this out. By the way, kglad you seem you would like to ignore that kind of a problem because that you dont have but there is suc problem, check out google for "cpu usage flash" keywords...

    I have the same problem over here. I hate to dive into complexity regarding this, but there are two things happening that might be relevent. Firefox when examined with process monitor seems to be recursively creating and killing threads which accounts for upwards of 20% of the cpu usage, these extensive bouts of activity are preceded and punctuated by queries, read, and writes of "C:\Documents and Settings\Open\Local Settings\Temp\fla64.tmp". A second potential relevent note is that we should post what extensions we are using to see if we can track it to one of them. I use many to be efficient "Tools -> Addons -> My Config". I attempted to kill the cpu usage first with google desktop, disabling history, advanced, and safe browing features to no avail.

    Seems as if a lot of us are having the same problem, with decent hardware specifications too....

    KGLAD - any sugestions for us all?

    i never noticed that problem but i'm seeing cpu usage between 30% and 40% with that home page design.  and that's way too high.

    what about the mandelbrot snippet?  that's actually very cpu intensive and i'm seeing less than 10% during the draw-phase.

    I too am frustrated by the very real problem with flash and CPU usage. I have a dell Precision 390 workstation and should not have my system come to a crawl whenever I go to a web site that has some silly ad that I am absolutely not interested in. I wish that they had a utility like FlashBlock for IE. Adobe seems to be silent about this issue. It would be nice if they would acknowledge it and say that they are working on a solution. At least allow the user to fine tune some optimization parameters so as to create an acceptable balance between performance and video experience.

    Great post guys..shame that Adobe don't seem to be listening. I have the same problem and its really starting to annoy me.

    These are my specs:

    Mac OSX 10.5.6

    Firefox 3.0.8

    Flash Player 10.0 r22

    ADOBE - PLEASE FIX THIS

    Thanks,

    Chris

    it's not adobe's fault that it's possible to stress your cpu using applications created by one of their products.

    just because someone has poor coding skills and uploads a poorly coded file onto their website that causes problems doesn't mean adobe should do anything about it.

    here's that same file with more reasonable coding:

    http://www.kglad.com/Files/31-framespersecond.html

    and while that still may put some stress on your cpu because the glowfilter is cpu intensive, my file should look better, run better and put less stress on your cpu than the original authors file.
