Thank you for your answer, but I had already done that
(File->Preferences and RENDERER=0), and if I move (with Trackball
object) my 3D model, it's as slow as if I put RENDERER=1, and my CPU
works 100%, so I think it's Mesa3D which works ! My video card is a
Nvidia Geforce FX 5700, and others win32 openGL applications works fine.
So it's not a driver pb... :( I don't understand why IDL Virtual
Machine doesn't activate hardware rendering...
