Is Pentium III really capable to play 1080p?

Does Nvidia integrate the purevideo in its video card drivers or still seperate it for selling?

The 8400 is quite old. I'm sure someone has discussed that on the web. But I didn't see good video play until the P4 3GHz days. Yours is well under that. In fact my oldest laptop was a TER600 and it's P3 600MHz could play Video DVDs fine. But that was 480p!

However, I hardly believe Pentium III can play 1080p, maybe the most powerful P3 - Tualatin 1.4G could make it.

Now, my Dell dimension 2400 can play 1080p with the MPC(not MPC-HC), the most lightweight video player I have ever used. The CPU usage is about 5% to 15%, but mostly below 10%. Other players, such as VLC, GOM, and MPC-HC can't even play 720p.

or others online, or were these ones stored on your hard drive and played from there? I've noticed something new and odd with youtube videos when using my Sempron 145 Linux computer. If I stay on the page, the CPU usage doubles on the 720p and more than it used to be, yet if I leave it playing in background and move to another page, the CPU usage drops back to where it used to be. Might be something wrong with the flashplayer on my computer, but it has to be some change youtube made, because nothing changed here, I'd even blocked any flash upgrades. Guess I'll try the upgrade, see if it corrects the double use of the CPU over what it had before.

It couldn't play 720p in youtube, even 480p is not smooth and the CPU usage is 80% to 100%.

It seems that the flashplayer is not optimized for GPU, at least not for Geforce 8400gs.

I've been having problems maxing CPU on youtube flash and that's on Linux version Firefox using both the previous adobe flash plugin and the current one available to me. I've charted my CPU while starting the youtube and after a bit of play, stop the video where it's as, then let it play again, and seen the CPU use drop to half of what it was before. It makes no sense. My guess is with the latest exploits directed at adobe and flash, they've done a massive code dump into it with intention refine later and glitches still exist. Here's more sources on google for just since January this year.

So, maybe some exploit is affecting you, or glitch in the latest flash player that's been released, but you are NOT the only one.

I used to be able to test against two 720p using my single core Sempron 145 and that with onboard video and not max it out, but youtube now for the same test is lucky to run the 720p without nearing max, and then if I stop and start soon after video starts, I can start and stop a 360p also before maxing the CPU, sometimes.

Video of Snoopy and Red Baron at utube, playing using the latest Flash Player plugin for Firefox, in Linux Mint 17 OS, tracking the CPU percent of usage while starting, then stopping a minute later, and then starting the video and running till it ends. Shows how it maxes the CPU until it's briefly stopped in place and then restarted. That's a 2.5 times more CPU power used in the first minute than when after a stop and start in place the usage drops to what is close to normal for the 360p video. Even then in the second part it seems a wee bit higher than it would previously have been.

Adobe needs to get this fixed!

I discovered I was still using the HTML5 player in the above example, instead of the newest Adobe Flash Player. I went to the Utube/html5 page and turned it off, opting for the "default" which is the browser's flash plug-in. What a change!

Here's a new CPU graph with explained time points on it. This is more like what I had before.

So, check and see if you are using the HTML5 player there and if so, try the flash plug-in for your browser instead.

This 8400gs may be a rev. 3 one, which is better than rev. 1 and 2.
