Comments on: Flex tip: a higher frame rate even makes text entry look better

Paul, I don’t have the original sample, but this works for me (perhaps you were setting frameRate instead of stage.frameRate):

I was just wondering if there’s any source for the slider that changes the frame rate? I’ve tried setting the frameRate property at runtime in my Flex app, but it seems to be ignored?

I just increased the framerate on my Flex/AIR app to 60 and it noticeably smoothed out a resize transition effect. Nice!

Something you have to know is flash is hardware accelerated, means use your graphic card. If not, use your proc. So I am not sure the framerate makes a big difference (not for me with my super card!) I dont manage to find a good official doc about it.

Hello,

I played a little bit with the text components. Currently I am writing a small editor for syntax highlightning.

A test example can be seen here, everything is only pre alpha but fun:

http://vehiclelan.com/eng/Editor-Test-Page.html

The situation which I observed:

You have two barriers when examining repeated key events:

1) Flash/Flex frame rate.

Basically 24 frames are sometimes too slow to react to a fast key repeat.

I recommend for a crispy input taste to increase the frame rate like described in this article.

2) Operating system key rate. If on the operating system side the key repeat rate is too slow, for sure even Flex or Flash frame rate increase will not help.

So if you cannot see any difference in these examples it is because of your operating system settings.

I tried Safary, IE and Mozilla firefox and all worked fine after checking the OS settings.

Greetings,
Martin

A frame rate of 60 fps is optimal in most occations since nearly all LCD-monitors runs at that speed. No interpoliation will be needed by the graphic card etc. A framerate of 50 fps may result in worse output. Still though, all screens do not run on 60 fps…

this probably goes without saying, but increasing your framerate is not always advisable; if your app has a main loop that is framerate-dependent (happens in an Event.ENTER_FRAME handler), you could be substantially increasing your CPU usage. games are one obvious example.

that said, it blows my mind to see a framerate slider on a swf! awesome.

Mike R. is right. The path from Flash Player to your eyes also includes your monitor. Make sure your monitor’s refresh rate is at or above 70Hz. This is the beginning of the flicker-free zone. Optimally, go for 85Hz.

With refresh rates above 70Hz, I’ve never had a problem with text area flicker.

I hope this isn’t a polar issue. :P

Now that the final Flex Builder/FP9 have been out for a bit, I’d like to hear thoughts on this topic again.
