Re: Expected frame rates for a full-screen blur
What version of jdk and Swing did you use? Can you check it on the latest jdk8? Ah you're right, Swing does hidpi these days. When I made the decision to start using JFX it didn't. But last time I tried the IntelliJ Oracle JVM builds the UI was pretty messed up so it seemed to still have some bugs. But that was maybe 6 months ago or more.
Re: Expected frame rates for a full-screen blur
OK, now I'm really puzzled - I watched the JavaFX performance talk from
2011 and learned about PeformanceTracker. It's too bad that's not public
API, but it works. I used it like so:
PerformanceTracker tracker = PerformanceTracker.getSceneTracker(scene);
tracker.setOnRenderedFrameTask(new Runnable() {
long lastTimestamp = System.currentTimeMillis();
@Override
public void run() {
final long now = System.currentTimeMillis();
long delta = now - lastTimestamp;
if (delta 1000)
System.out.println(Frame took + delta + msec);
lastTimestamp = now;
}
});
The 1000 thing is just to avoid printing a nonsense timestamp when the UI
hasn't been touched for a while.
The deltas I see are consistently between 10-20msec which would be between
50 and 60fps, i.e. the vsync of the screen. But the wacky thing is, this
doesn't change when I increase the size of the window, even though the
animation is noticeably more choppy. It still says there's a 10-20msec gap
between frames even though my eyes tell me otherwise. Even when I shrink
the window size right down and get super smooth animation, the above code
prints the same kind of deltas.
This makes me think that whatever is going on, the regular JavaFX drawing
thread isn't the issue. It seems to be churning through the scene at the
same totally acceptable rate no matter what. So I'm thinking the issue must
be something to do with how fast the GPU drains the command queue or
something.
BTW I tried doing -Dprism.order=j2d to see what would happen, and the GUI
hangs before rendering anything. I'll file a bug on that later.

Re: Expected frame rates for a full-screen blur
You might also want to try using the PulseLogger (which was recently refactored
to be usable from Java Flight Recorder). See
http://hg.openjdk.java.net/openjfx/8u-dev/rt/file/978e5c042214/modules/base/src/main/java/com/sun/javafx/logging/PrintLogger.java.
Basically a few system properties are needed and then you should get per-pulse
data that breaks down the time spent in different places. It seems like it
shouldn’t be the case, but it looks like you’re fill rate limited. Maybe we are
sending really huge bitmaps down to the card and the card bus just can’t keep
up?

Re: Expected frame rates for a full-screen blur
Right. My issue appears to be far more general - any large window has poor framerates no matter how simple the contents seem to be. What's more it doesn't seem to be a pure CPU time issue because *all* graphics operations, even things like opening mission control, also end up lagged. So I feel it's more likely to be something to do with the GPU, as that is a shared resource that perhaps isn't being timesliced very well. I can't offer a better explanation of why an app would be able to drag down the responsiveness of the entire OS. I tried changing the blue type, adding cache hints and so on. No difference. I also found someone else complaining about this: mihosoft.eu/?p=486 The issue very specifically seems to be large windows. I tried changing the display resolution as well, but unsurprisingly the only thing that made it faster was changing the scaling so all windows were smaller. Modifying the display settings to give me more space just made things worse (larger window again). I'm not sure how to go about diagnosing this. Again - does anyone else see their entire OS tank when the Ensemble coloured circles demo is run?

Re: Expected frame rates for a full-screen blur
Actually, Box Blurs are no more efficient than Gaussian on GPU hardware due to the inability of shaders to perform incremental operations from pixel to pixel. Both are implemented by convolution kernels and N multiplies per pixel in the first horizontal pass and M multiplies per pixel in the second vertical pass (where M and N vary by radius/size of the blur and number of box passes)... ...jim On 4/1/14 2:16 PM, John Smith wrote: Sounds like your issue isn't in fact the blur, but, if it were, some things suggestions are: 1.

Re: Expected frame rates for a full-screen blur
The tick marks in the MacOS display settings do not turn off retina support, they only affect the amount of scaling within the retina spectrum that is provided. To turn off retina support you need to use a utility like QuickRes that allows you to specify HiDPI (retina) vs. non-HiDPI resolutions. HiDPI retina resolutions always render at a scale factor of 2.0 and then they scale them to the indicated screen size. The best for retina resolution is the resolution in which the rendering at a scale of 2.0 exactly matches the number of pixels the window will be scaled/blitted into. Regular resolutions will render at a scale factor of 1.0 and also scale to the indicated screen size, and so the scaling artifacts will be much more noticeable unless you choose the precise native resolution of the display itself... ...jim On 4/1/14 11:17 AM, Jeff Martin wrote: I assume retina optimization was added for JFX 8 (or is on the short list).

RE: Expected frame rates for a full-screen blur
Sounds like your issue isn't in fact the blur, but, if it were, some things suggestions are: 1. BoxBlurs are more efficient than GaussianBlurs: http://en.wikipedia.org/wiki/Box_blur 2. Apply some of the suggestions from the openjfx Performance Tips and Tricks page: https://wiki.openjdk.java.net/display/OpenJFX/Performance+Tips+and+Tricks Anecdotally, applying the Performance Tips and Tricks allowed smooth animations on a 2012 MacBook Air with a full-screen blur. -Original Message- From: openjfx-dev [mailto:openjfx-dev-boun...@openjdk.java.net] On Behalf Of Jeff Martin Sent: Tuesday, April 01, 2014 11:17 AM To: Mike Hearn Cc: openjfx-dev@openjdk.java.net Subject: Re: Expected frame rates for a full-screen blur I assume retina optimization was added for JFX 8 (or is on the short list). I think there is a Jira for it. You can choose a non-retina resolution by going to display preferences and clicking the Scaled radio button and selecting something to the right of Best Resolution (Retina). It used to be that you could option-click the Scaled radio button to get a real list of choices, but now you can only get that with a 3rd party resolution tool (I think). jeff On Apr 1, 2014, at 12:49 PM, Mike Hearn m...@plan99.net wrote: How do I do that?
