JOGL 1.1.1 App on new ATI Card and Drivers (HELP!)

[Grant]

Hi
I am trying to run an app built with JOGL 1.1.1 on a Linux box that has a brand new ATI graphics card and the latest ATI Linux drivers installed. The performance is beyond bad, the app is unusable.

When running the app the X server is running at 100% CPU continuously. GL test applications (e.g. glxgears) run without a problem.

The ATI tools are telling me that the card has OpenGL 3.x (can't remember exact number). The strange thing is that the app runs without a problem with an nVidia card and latest drivers installed.

I recall reading somewhere that there is potentially an issue with the move from OpenGL 1.x or 2.x to 3.x that may not work work JOGL 1.1.1 but nVidia had some driver tweaks that got it to work.

Has anyone successfully got an app built with JOGL 1.1.1 to work on a new ATI card and drivers on Linux. Is there something I can do to teak the ATI drivers to get it to work. In theory the new ATI card should be a lot faster than the older nVidia card that I have.

TIA

Rather use JOGL 2 as JOGL 1.1.1 is no more maintained
