Question

FULL_SCREEN, Stage3D and OS/X is very slow?

I can't find the previous version of thread, the last email I had with an update shows it as having been deleted.

Anywho, here's a demo showing the issue.

On my Mac Mini ( purchased last year ), in Safari if I stretch this link to full-screen, it is very fast ( basically full-screen other than the top header ).  If I press the Full Screen icon in the top right, the frame rate drops a LOT.

Here's the link...

( click on the Search icon, type some text to google image search for, and press RETURN or ENTER, then wait ).  Note that some images won't be loaded due to crossdomain.xml issues - we have an optional local proxy server solution which will load all of the images, but this doesn't show loading progress ).

I'd be interested in hearing if any other OSX users are seeing the slow down problem ( or even Windows users ).

Many thanks...

Mal

I don't think it's a fullscreen issue, the pwerformance is poor even if I just make the browser window bigger. It's as if you're not using GPU at all.

Interesting.  I'm running 10.8.4 on one of the retina MBPs with an old-school cinema display attached, and I'm not seeing the performance issue, even when vigorously scrubbing the mouse around -- it's snappy.

I don't have easy access to an older mac mini at the moment, but I can find someone that does.  Can you give me the pertinent details from About This Mac > System Config so that I can direct them to the right hardware?

Colin, any chance you're running the content debugger?

Can you give me info on which machine you have (i.e. Retina 15", Early 2013) so I can ask someone check it out on comparable hardware?


I’m using the more recent 13 inch Retina MacBook Pro, and I see the lower frame rate with either the internal LCD screen, or with a connected 27 inch monitor. In either case 11.7 performs well. 2.9 GHz, i7, 8GB RAM Intel HD Graphics 4000 1024 MB.

When I look at this in Safari with Flash Player 11.8.800.95 on OSX 10.8.4 is that performance is fine in both embedded and full-screen, unless the app is actively trying to load images.  Once the loading process is complete, performance returns to normal.

I see a similar performance hit in Firefox, but it definitely appears to be more severe in Safari.  Most of the network activity is handled by the Browser, so it may be more performance intenstive there.


I'd recommend taking a look with Adobe Scout to see if you can identify any hot spots in your code.

Hi Jeromie,

Thanks for taking a look, and for the feedback!

The performance drop I'm seeing is just going from windowed to full-screen ( even if no images are loaded ) - the FPS drops from a very smooth windowed version, to a mildly smooth full-screen version.

I'm seeing the issue on a Mac Mini ( about a year old ) with 10.8.4.

The loading performance hit issue is mainly the fact that I'm kicking off 50 image loads in a short space of time - I'll code up a system shortly to load a limited amount, and try a new load as an old load completes, but this is a different issue that I'm seeing from toggling full screen / windowed.
