Hi, ai am having problems with performance, from time to time (almost each 10 seconds) the CPU usage goes to 100% on the applet and then it stops responfing for 5 or 6 seconds, and then continues on the same way. Any ideas?
I am using a Centrino 1.6, 1Gb RAM, ATIX600, and I am running a GL Canvas inside an applet.
The code is quite simple, The class that does all the Rendering is:

Anyway the web part is finished and now I am implementing the 3d part with jpct. I will post some pics sooner.
