Severe Sporadic System Slowdowns?

(Say that five times fast ;))

I’ve got a GLCanvas in a Swing app, and sometimes my entire system seems to become unresponsive for short periods of time (probably 2~3 seconds, but it sure feels like more :P) while the application is active. I notice it consistently when I move the application window, but I noticed it occasionally when appending text into a textarea and forcing the textarea to scroll…

Needless to say, I’m concerned about this behaviour. I really want to use JOGL in this application, but if I can’t get a reliable steady framerate, then I won’t be able to. :-\

After the system ‘unfreezes’, when I had taskmanager open already, ‘java.exe’ was running at 100% CPU.

I plugged in the FPSAnimator to see if it made a difference (either way, I’ll be using it).

I’m running a Windows XP system with loads of RAM and a decent video card.

I’m running the application from within NetBeans.

Thank you! Hope that’s enough info to get a lead!

Well I turned off ‘Dislay window contents while moving window’ in the windows display settings and it’s not quite as bad… Seems like a hack of a solution though. :confused:

What kind of video card (type of chip)? Are you running the latest drivers from your vendor?

Are you running the latest build of JOGL (1.1.1)? What is the output of jogl -Djogl.verbose demos.printext.PrintExt?

What version of the JDK are you running?
