New issue 181386 by danny.du...@gmail.com: Pepper Flash player much higher
CPU usage
http://code.google.com/p/chromium/issues/detail?id=181386

UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2)
AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.160 Safari/537.22

Example URL:
http://www.youtube.com/

Steps to reproduce the problem:
1. Open Activity Monitor
2. Play video in HD on youtube. Record CPU usage by pepper flash player
3. Play same video in HD in Safari. Record CPU usage by Adobe Flash player

What is the expected behavior?
CPU used by Pepper will be significantly higher (on my PC around 30%) than
the native Adobe Player (around 9%).

What went wrong?
As above - Pepper is using 3x more CPU. And that eats up battery...

Did this work before? N/A

Is it a problem with Flash or HTML5? Flash

Does this work in other browsers? Yes Safari 6.0.2

Chrome version: 25.0.1364.160 Channel: stable
OS Version: OS X 10.8.2

I tried to disable Pepper player to use native flash player, however result
is that flash is no longer hi-dpi (or retina, I'm using Retina mac). Native
flash player on Safari plays video using full physical resolution machine.
In Chrome however, after disabling pepper, flash displays scaled down and
blurry (non-retina).

Sorry, of course expect behaviour should be:

CPU usage more or less the same regardless of player/browser used.

I have the same problem on Windows 8. 8% IE/Firefox, 20% Chrome with Intel
i7 950 processor. Not only related to Mac OS.

much higher CPU usage
http://code.google.com/p/chromium/issues/detail?id=181386

Confirming, PPAPI flash player eats not only CPU, but at least 2x more GPU
on our application than NPAPI flash player when using wmode=direct or
wmode=gpu and drawing Stage3D graphics. Also the drop in FPS is very
significant.
IE 9, 10 and FF play application also much smoother with far less gpu power
and lagging.

Windows 7 32bit
Chrome 31.0.1650.57
PPAPI plugin 11.9.900.152
vs
NPAPI pugin 11,9,900,117

Confirmed on retinaMBP 2013 with discrete graphics.

I have to switch to safari as my default browser because of this ongoing
problem.
