To explore OpenGL, be advised:

"Be sure that your graphics card is OpenGL 1.3 or higher compliant  
AND that you have appropriate OpenGL hardware drivers installed.  
Windows users should be aware that upgrading your DirectX versions  
through Microsoft's web site often overwrites existing hardware  
OpenGL drivers with software OpenGL->DirectX wrappers (killing  
performance, if not compatibility). The fix is to re-install the  
video card manufacturer's drivers after any DirectX install procedure."

The above is from the Croquet downloads page. There has been  
discussion of driver issues on the Croquet mailing lists and wikis...
